# Matrix display with controlled equivalent area for differentiating characters

FIELD: information technology.

SUBSTANCE: in the matrix display, digital format position elements are distributed on 9x9, 7x7, 5x5, 3x3, 1x1 format loops, illumination or black out of which causes change in the number of point elements therein, while maintaining, when formatting digital characters from 0 to 9, constancy of the number of point elements therein, which corresponds to the changed number of displayed point elements in the format loops, and the decimal point is displayed on the character either by blacking out or illuminating the 1x1 format loop depending on whether it is illuminated or blacked out when forming characters.

EFFECT: reduced power consumption irregularities from character to character owing to providing equal surface area of illuminated point elements of a character.

The present invention relates to display devices of information (SDI), a significant scope of which represent the matrix segment and symbolic indicators (SI).

The indicator matrix variable is equivalent to the square of the distinguishing marks can be used in all means of information display, in which an improvement of the perception of numeric characters.

The greatest volume information in a variety of computing devices and measuring equipment is on display semipositone decimal digits.

The disadvantages of the mark semipositone digital signs should include a large number of positional elements included in a digital format, from which are formed the decimals, the uneven distribution of positional elements in signs, low resolution characters in width and height; the uneven energy consumption in the formation of character. The result: low perception of signs and a low rate of identification.

The desire to achieve better distinguish between numeric characters change their style and reduce the overall size of the digital format (by reducing the number of point elements in it) will result in neprilichnosti characters.

The strangeness of the characters should be in the op is audana best ergonomic parameters of the perception of them - the greatest resolution as the height and width of the sign.

The aim of the invention is:

1. reducing the overall size of the digital format character height;

2. improved parametric characteristics of digital signs: increased resolution in height and width;

3. the reduction of non-uniformity by the number of point elements in the signs;

4. the reduction of non-uniformity of the energy consumption in the signs;

5. increase the dynamic range of the variation of a quantity equivalent to the area of discernment.

This goal is achieved by the fact that in the information field of the indicator are formed numeric characters, font style, which provides the greatest resolution of their perception.

An important requirement of the indicator is to ensure the possibility of the perception of the displayed digital information with the specified distances of the observations. Based on these requirements, establishes the requirements for the parameters SI: the viewing distance, the angular size of the sign, the linear size of the sign height /1 - p.98/.

For a correct choice of the linear dimensions of digital signs (height, width, thickness, contour mark) it is necessary to know the angular size of the sign is determined by the visual acuity. The angular size of the sign is the angle between the two beams directed from the eye to the extreme point is m (lines)

α=2arctg(h/2L), h=2Ltgα/2, L=h/2tgα/2, where h is the linear size of the sign height; L is the distance from the eyes to the sign; α is the angular size of the sign or the angle at which visible sign /2 - p.115/.

Based on the distance of observation L established empirically, and the optimal values of the angular size of the sign, find the height of the sign of h. Knowing the height of the sign, you can calculate its width, thickness, contour mark, and the distance between marks. Width shall be (3/5)h, the thickness of the outline of the sign - (1/8)h, and the distance between marks is 1/2 the width of the sign /2 - str/.

However, to quantify the perception of the displayed digital information is not enough these values found experimentally. For example, the perception of the different characters of the same seven-segment format display will be different at the same distance observation and at the same angular size. Figures 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 (pigv) differ in the number and arrangement of the segments different amount of space select the function of the positional elements of the sign, and the value of the square ("window"), located between the positional elements, different resolution. The resolution of the mark is measured at the possibility of distinguishing the operator of two playable lines, some distance from each other / - p.115/.

For example, when considering the alternate digits of seven-segment format indicator it should be noted that at the same height of the displayed characters and their angular size height range observations on the formula one and the same (L=h/2tgα/2). But it cannot be said that the perception of any segment of the mark with the same distance was the same. If you compare the drawing of numeric characters 8 (figa) and 0 (figb), it appears that a distance when considering the digit 0 can be increased. The effective angular size of height 0 twice or another, more resolution, height /3/ due to the absence of the middle segment in the drawing of this figure. Figure 7 has the highest resolution due to the fact that its mark there are only two segments (horizontal and vertical) and in addition to these segments, there are no other vertical or horizontal segments that are at some distance from them, worsening the discernment operator of this sign. Other signs seven-segment format (except figures 1 and 7) have a mark or two vertical, or three horizontal segment, worsening the perception of them.

Under the perception to understand the process of holistic reflection items arising from the direct impact of the physical is their stimuli (stimuli) on the receptor surface of the senses. This multi-level process, ending with the formation of a sensual image, includes the following stages: detection, discrimination, identification, recognition /4 - p.46/.

The detection stage of perception, on which the operator selects an object from the background. This is only the presence of a signal in the field of view without assessing its forms and signs /4 - p.46/.

To quantify the perception of the characters on stage detection without assessing its forms and signs of use overall dimensions of the information field matrix indicator (8×8=64 mm^{2}type CIPROE-8×8L /5 - str/ without taking into account the distances between point features. Matrix display method, for convenience of calculations will clearly not putting size on the figures, to determine:

1. the dimensions of the characters in width (L) and height (h);

2. the area occupied by the sign (S);

3. the area occupied by the positional display elements of the mark (S);

4. the area, located between the positional display element (size of the "window" - S);

5. the thickness of the outline of the character (s).

Dimensions of the element radiation information field of the matrix on any piece of application materials received 1×1 mm^{2}.

Giving the space a positional display elements of the mark (S), values from 0 to 64 mm^{2}(the ri displaying characters use all the information field indicator CIPROE-8×8L) discretely through 2 mm^{
2}it is possible to trace the dependence of the ratio of the area of the positional elements to a square "window" (S/S) from square positional elements (S). You can also see an inverse relationship - the ratio of the area of the "window" to the area of the positional elements (S/S) from square positional elements (S). The area occupied by the "window" (S), calculated by the formula S=S-S where S - the area of the sign is equal to 64 mm^{2}(S=S+S), occupying all of the information field of the indicator. On high-Figl displayed filling in the information field of arbitrary shapes with a certain size that is a multiple of 2 mm^{2}, positional elements.

For each pair of values S and S, at a constant square mark (S=S+S), we find the ratio S/S (assuming S<S) and all digital data tabulate No. 1 (figa).

According to table No. 1 was built increasing the area of ASM (S=0-32 mm^{2}curve (from zero to point M) dependence relations S/S (figa) from the square of positional display elements of the mark (S). Points a, b, C, M curve correspond to the values area of the positional elements displayed on high-Figg respectively. In table 1 these points are marked with asterisks. The maximum value of the magnitude of the relationship S/S is equal to 1 (point M, Figg), can be achieved with equality square positional elements and square "window" (S=S32 mm^{
2}). The ratio S/S characterizes the possibility of detection of the mark without assessing its shape. And more than this value (when S<S), the detection capability of the sign above. On the ascending portion of the curve ABCMDEF (figa) the possibility of detection of the mark is increased (high-Figg), when a smaller surface positional elements (S=0-32 mm^{2}) stands out against a larger area of the "window" (S=64 mm^{2}- 32 mm^{2}).

At the point M of the curve ratio S/S (S<S) is equal to the inverse value of this ratio (figs) S/S (S>S), which also characterizes the possibility of detection of the mark. At this point, the possibility of detection of the mark maximum (S=S).

To build the descending portion of the curve (figa), for each pair of values S and S (S>S), we find the ratio S/S (S<S) and all digital data tabulate No. 2 (figb). According to table No. 2 built decreasing plot MDEF curve (from point M to the right to 0) according to the relationship S/S from square positional display elements of the mark (S). Points M, D, E, F of the curve correspond to the values area of the positional elements displayed on figs-Figl respectively. In table 2 these points are marked with two asterisks.

On the descending portion of the curve ABCMDEF (from the point M to the right to 0) the possibility of detection of the mark is reduced (figs-Figl) reducing a square "window" (S=32 mm^{
2}- 0). Increasingly detected size of the "window" on the background of a larger area of the positional elements (S=32 mm^{2}- 64 mm^{2}).

Curve ABCMDEF consisting of ascending and descending sections, characterized by the possibility of detection of the mark depending on the ratios:

1. square positional elements to the square "window" (S/S) on the ascending portion of the curve when S<S from 0 to 1 (increasing the possibility of detection of the mark);

2. square "window" to the area of the positional elements (S/S) on the descending portion of the curve when S<S from 1 to 0 (reduces the possibility of detection of the mark).

The symmetric shape of the two plots with the total curve is relatively straightforward (OMN)passing through the point M is perpendicular to the x-axis confirms the equivalence of values S/S and S/S possible detection of a mark located on opposite sides of the symmetry axis.

Maximum detection capability of the mark (point M on the curve) is a condition in which the area of the positional elements equal to the square "window" (S=S). And, therefore, the ratio of the area of the positional elements (S) to a square "window" (S) is equal to 1 (S/So=1) or that the same is equal to 1 the ratio of the area of the "window" to the area of the positional elements (S/S=1).

Only when the equality of values of a square "window" and the area of the positional elements (S=S the possibility of detection of the mark maximum (S/S=1).

Point M (figa), which meets the condition of equality of the square positional elements and square "window" (S=S=32 mm^{2}following the results of the calculations (S/S and S/S)related to Figg and figs. In two tables No. 1 and No. 2 (figa, figb) these results are marked with one and two asterisks, respectively.

Similarly a curve GHIMJKL (figa). To construct this curve selected another method, which is characterized by the fact that the function is equal to the product of the arguments (S×S)divided by the sum of these arguments (S+S), expressed by the size of the dimensions of area (mm^{2}). I.e. a numeric value functions show not just the possibility of detection of the mark, in relative terms, and show the magnitude of equivalent area detection (S) sign at each point of the curve. Curve GHIMJKL reflecting the function S=(S×S):(S+S) depending on the magnitude S corresponds in each point of the particular overall size of the sign (the format of the matrix is 8×8), within which changes the area of the positional elements, and the size of the" window" (S=S+S).

The maximum of the curve GHIMJKL at the point M coincides with the maximum of the curve ABCMDEF at the same point M at the desired scale on the ordinate axis. At this point, when the equality of the square of positional display elements of the mark and space of the "window" (S=S=32 mm^{2}) is m ximala the possibility of detection of the mark (S/S=S/S=1).
Moreover, the maximum detection capability of the sign is confirmed by specific, with dimension (mm^{2}), a value equivalent to the detection area of the mark (S).

The results of calculations for the equivalent area of the detection mark

S=(S×S):(S+S),

which built curve GHIMJKL recorded in table No. 1 and table No. 2 (figa, figb). The curve is increased by the points G, H, I, J, K, L shows the results of calculations related to high-Figg and figs-Figl respectively, and in table No. 1 and table No. 2 these computations allocated one and two asterisks.

In table 1 the results of the calculations show the amount equivalent to the area of detection (S) the sign occupied by the positional display elements of the mark (high-Figg) on the background square "window" when S<S.

In table 2 the results of calculations show the amount equivalent to the area of detection (S) sign (figs-fill), the occupied space of the "window" on the background position of the elements when S<S.

Point M, which meets the condition of equality of the magnitude square of the positional elements and value of the square "window" (S=S=32 mm^{2}following the results of a calculation equivalent to the area of detection of the mark related to Figg and figs. In two tables No. 1 and No. 2 (figa, figb) these results are marked with one and two "star who points respectively.

Curve GHIMJKL characterizes the change in the value equivalent to the area of detection of the mark depending on the ratios:

1. square positional elements to the square "window" (S<S);

2. square "window" to the area of the positional elements (S<S).

In the first case the value of the equivalent area of detection of the mark is increased (high-Figg) by increasing the area of the positional elements in ascending plot GHIM curve (S<S) from zero to the point M (actually found in the field of view value is equivalent to the square of the position elements on the background square "window").

In the second case, the value of the equivalent area of detection of the mark is reduced (figs-Figl) by increasing the area of the positional elements on the descending portion of the curve MJKL (S<S), starting from the point M (actually found in the field of view of the value of the equivalent square "window" on the background of a larger area of the positional elements).

The maximum value of equivalent area detection at a constant square format indicator is achieved by equality of square positional elements and square "window" (S=S=32 mm^{2}). Other ratios of the square values of the positional elements and square "window" size is equivalent to the square of the detection of the mark will be less.

Figure 1 l, for example, shows that the magnitude square of the window is equal to 4 mm^{
2}(4 point matrix element), the value of the square of the positional elements equal to 60 mm^{2}and the magnitude of the equivalent area detection (S) sign, as determined by a formula shows 3.75 mm^{2}.

When S<S actually found in the field of view of the value of the equivalent square "window" on the background square positional elements. The discrepancy in the magnitude square "window", is presented in figure 1 l (S=4 mm^{2}), with the result of calculations by formula (S=3.75 mm^{2}) due to the relativity of the perception of a low magnitude square "window" on a limited area of positional display elements of the sign.

For example, if you save the size of the "window" S equal to 4 mm^{2}and to increase the area of the positional elements of the sign S, say, 10 times (S=600 mm^{2})while increasing the overall size of the sign, the result is equivalent to the square of the detection of the mark will approach indicated in figure 1 l is the size of the "window"is equal to 4 mm^{2}:

S=(S×S)/(S+S)=(600×4):(600+4)=3.97 mm^{2}.

Similarly, if high the size of the positional elements of the sign equal to 4 mm^{2}(4 point matrix element), and the size of the "window" equal S=60 mm^{2}value equivalent to the area of detection of the mark will be less (S=3.75 mm^{2}values of the square positional element (S is e=4 mm^{
2}).

When increasing the square "window"at a constant square positional elements, for example, up to 600 mm^{2}while increasing the overall size of the sign, the magnitude of the equivalent area of detection of the mark will also increase, approaching the size of the positional elements displayed on Figg:

S=(S×S)/(S+S)=(4×600):(4+600)=3.97 mm^{2}.

To trace the dependence of the equivalent area detection (S from the size of the square mark(S=S+S) at a constant value square positional elements, with the magnitude square "window", you can use the chart (figure 4).

Three curves 1-1, 2-2, 3-3 constructed according to the tables (file, file, file respectively). The size of the "window" (S) and the value of the equivalent area of the detection mark S=(S×S):(S+S) listed in 2 and 3 columns of these tables at a constant square positional elements (S=8 mm^{2}, S=16 mm^{2}, S=32 mm^{2}respectively for five, five, five). In the first column of these tables shows the number of figures (a, b, C, d, e - without "stars"), on which the calculation of the value of the equivalent area of the detection mark (S).

The value of the equivalent area of the detection mark (S) increase the area of the "window" is committed to the magnitude square of the positional elements. At a sufficiently large size of the "window" five -
4000 mm^{2}, five - 8000 mm^{2}, five - 8000 mm^{2}) the magnitude of the equivalent area detection (S=7.99 mm^{2}, S=15,96 mm^{2}and S=31.87 mm^{2}respectively) is close to the size of the positional elements (S=8.00 mm^{2}, S=16.00 mm^{2}and S=32.00 mm^{2}).

The point of intersection (1-2) curve 1-1 and 2-2 curve (figure 4) shows that the magnitude of the equivalent area detection (S=5.33 mm^{2}) at the same value of the square mark (S=24 mm^{2}) the same (fige and five). But the size of the positional elements of the sign on figb (S=16 mm^{2}, S=8 mm^{2}) two times greater than sign on FIGU (S=8 mm^{2}, S=16 mm^{2}).

Larger positional elements in comparison to the size of the "window" (when S>S) sign on figa gave no advantage in terms of the equivalent square in front of the sign detection on FIGU, with much smaller size of the positional elements.

Point (2-3) of the intersection curve 3-3 curve 2-2 shows (figure 4), which is equivalent to the detection area (S=10.67 mm^{2}) in the same area of the sign (S=48 mm^{2}) the same (fige and five). But the area of the positional elements of the sign on FIGU (S=32 mm^{2}, S=16 mm^{2}) two times greater than sign on Figg (S=16 mm^{2}, S=16 mm^{2}).

Increased the th square positional elements in comparison to the size of the "window" (when S> S) sign on FIGU gave no advantage in terms of the equivalent square detection with a lower value of the square of the positional elements of the sign on Figg.

Point (1-3) of the intersection curve 3-3 curve 1-1 shows (figure 4), which is equivalent to the detection area (S=6.40 mm^{2}) in the same area of the sign (S=40 mm^{2}) the same (fige and five), but the area of the positional elements of the sign on figa (S=32 mm^{2}, S=8 mm^{2}) four times more than the sign on Figg (S=8 mm^{2}, S=16 mm^{2}).

Larger positional elements in comparison with the size of the "window" (when S>S) sign on figa gave no advantage in terms of the equivalent square in front of the sign detection on Figg, with a significantly smaller positional elements.

The dependence of the equivalent area detection (S) from the value of area (S) sign (figure 4), the value of the square of the positional elements of the sign are equal to the square "window" (S=S)shows a direct 4-4, tangent to each of the curves (1-1, 2-2, 3-3) on points (4-1,4-2,4-3, respectively). These points correspond signs (figb - S=8 mm^{2}, S=8 mm^{2}, S=4 mm^{2}; figb - S=16 mm^{2}, S=16 mm^{2}, S=8 mm^{2}and high - S=32 mm^{2}, S=32 mm^{2}, S=16 mm^{2}), the value of the square positional E. the elements of which are equal to the square "window".

A plot of the magnitude of the equivalent area detection (S from the size of the square mark (S)based on the results of tables (file, file, file curve 1-1, 2-2 curve and curve 3-3, respectively), shown in figure 4. From this graph you can see that the increase in the area of "open" and constant area positional elements (S=8 mm^{2}curve 1-1, S=16 mm^{2}curve 2-2, S=32 mm^{2}curve 3-3) the amount equivalent to the area of the detection mark (S) is close to the size of the positional elements (S).

To use virtually the larger sign up to such size that the value of the equivalent area detection (S) mark reached a magnitude square of positional elements (S), does not make sense due to the significant increase in the overall size of the sign of the indicator.

The optimal characteristic when choosing the value of area positional elements (S) display and is the size of the "window" (S) for a given overall size of the sign (S) is straight, simultaneously tangent to the curve 1-1, 2-2 curve and curve 3-3. This line applies to each curve at those points, in which the observed equality S=S=S/2 for a given overall size of the sign (S=S+S). So, for example, by straight points 5, 6 and 7, the area of the sign are equal to, respectively, 24 mm^{2}, 40 mm^{2}and 48 mm^{
2}the optimal size of the positional elements will be 12 mm^{2}, 20 mm^{2}and 24 mm^{2}respectively. The value of the equivalent area of detection of each sign will be equal to 6 mm^{2}10 mm^{2}and 12 mm^{2}(figure 4).

The value of the equivalent area of the detection mark at these points equal S=(S×S): (S+S)=S/4. And when you increase the area of the position elements relative to the size of the "window", i.e. when S>S, when considering the overall size of the sign will not lead to an increase in the size equivalent to the area of detection, i.e. does not improve the possibility of its detection. Only when the equality of the magnitude square of the positional elements and value of the square of the "window" is achieved, the maximum equivalent area of detection (S) sign and the maximum possibility (S/S=S/S=1) detection (point M on the curve ABMCD and curve EFMGH - figa).

Discernment - the stage of perception, on which the operator is able to select items, the positional display elements of the sign /4 - p.46/. The ability of display devices to reproduce small details that characterized their resolution. Resolution is one of the parametric characteristics of the indicator is determined by the peculiarity of perception of visual information man - Opera is the op. Resolution is defined as the maximum number of separate sites per unit length or the surface of the indicator, with enough of their perception of the contrast. Quantitatively, it is estimated by the number of pairs of optical lines ("line amount")per 1 mm or 1 cm, or the minimum width of lines on the screen /4 - p.21/.

The resolving power of the indicators can be assessed for the possibility of distinguishing the operator of two of reproduced light dots or lines that are located at some distance from each other. At low resolution the operator takes two points (lines) for one, and at high resolution two very close points (lines) are perceived as separate. Increasing the resolution can up to a certain limit, above which the image is to be perceived by the eye /2 - p.115/.

The smaller the distance between the parallel spaced positional display elements in the mark, the less resolution of the sign, the worse the ability to distinguish between his.

Resolution width of the sign (n) on figa-figd determined by the number of pairs of line-interval" (the width of the "interval" select the width of the lines or equal to the thickness of the outline of the sign), increases from 1.5 to 5. Increases the ability to differentiate the sign from the age of the of the resolution. Increases equivalent area distinguishing mark. But to quantify the impact of increased resolution on the increase of the equivalent area of the distinguishing sign of the largest number of "vapor-span" these figures cannot. We can say only that the resolution of the mark width from figd more resolution of the mark width from figa.

In order to quantify the impact of the resolution of the mark in terms of the equivalent square in distinguishing it, you must associate a value representing the resolution of the mark width is equivalent to the detection area.

To do this, enter the ratio of the resolution width (Cross) sign. And using this ratio to calculate the equivalent area distinguishing mark (S) by the formula:

S=S:Cross

The value of the coefficient resolution reduces the possibility of the perception of the sign and the speed of its identification.

To determine the resolution of the sign (figb) width (Cross) easier resolution to Express not the number of pairs of line length, and the thickness of the vertical positional display element of the sign (s).

Using the width of the outline of the sign measure the gap (a) between one vertical line of the sign to the border of Shirinskaya (pigv) and gap (b) between the opposite vertical lines mark (high). I.e. measured thickness contour sign (figb) the distance from one vertical positional display element to the border (figv width characters (a) and measured the distance of the gap (b) between the two vertical positional elements (the width of the "window") character (Figg).

The possibility of distinguishing one (pigv) vertical position of the element in the one case and the ability to distinguish each positional display element (Figg), in the second case, when the same width of the sign. Quotient, a/b (dimensionless number) can be characterized as the relative magnitude of the resolution of the sign or the magnitude of the ratio of the resolution of the sign width (Cross=a/b). The greater the value (Cross=a/b), the lower resolution across the width of the sign.

That is, the magnitude of this ratio (a/b>1) reduces the possibility of distinguishing each of the two positional display element (Figg) in relation to the possibility of distinguishing only one positional display element in the absence of the second positional display element (pigv), with the same width of the sign.

We define the coefficients of the resolution (Cross=a/b) width of sign, consisting of two vertical positional elements located at the same distance from each other (figa), and two vertical positional elements located at a different distance from each other (figd). The values a and b (figa and figd), measured by the number of thickness positional element, determine the values of the coefficients of the resolution width. The relationship a/b (CRS=a/b) will be respectively equal Cross=2/1=2 (file, 1 line) and Cross=9/8=1.125 (file, 8 string).

To confirm the correctness of the calculation of the coefficient (CRS) resolution of either sign (figa, figd) check it another formula used for determining the value of an equivalent area of detection of the mark:

S=(S×S):(S+S)

Determines the magnitude of the equivalent area of one detection of the vertical position of the element in two (S-2) vertical (figa, figd)arranged in parallel at a certain distance from each other positional display elements, on the area they occupy (S+S), by the formula:

S-2=(S×S):(S+S):2 or S-2=S/2 (file - columns 2, 3 and 9 of the table).

Determines the magnitude of the equivalent area of one detection of the vertical position of the element in one (S-1) vertical (figa*, Figg*) positional display element located (five - columns 7 and 8 of the table) in the same square (S*=S) by the formula:

S-1=(S*×S*):(S*+S*)

The value is equivalent to the square detection (S-1) one positional element, located on a limited (S) space (figa*, Figg*) greater than an equivalent area of detection (S-2) the same positional element on the same limited space (S) at the location of the second position element at a certain distance from it (figa, figd).

The ratio S-1/S-2 defines the ratio resolution (five - 10 column of the table), when vertically stacking elements, the width of the sign (Cross=S-1/S-2). For Figo and figd factors resolution, determined by different methods of calculation (Cross=a/b or CRS=S-1/S-2) are exactly the same (coefficient Cross for figa equal Cross=a/b=2:1=2, or CRS=S-1/S-2=5.33 mm^{2}:2.67 mm^{2}=2, row 1 of the table, and for figd coefficient Cross=a/b=9:8=1.125 or Cross=S-1/S-2=7.20 mm^{2}:6.40 mm^{2}=1.125, line 8 of table five).

The coefficient resolution CRS=(S-1)/(S-2) shows the reduction of the equivalent area of detection of one of the two (S-2) positional display element (figa) in relation to an equivalent area of detection of one (S-1) when one of the displayed positional element (figa*), located in the same square. The higher the value of this ratio, the less the equivalent area of discernment (S) sign (S=S/CRS) For figa equivalent to the detection area of the mark (S=5.33 mm^{
2}) twice the equivalent area distinguishing mark (S=S/Cross=5.33 mm^{2}:2=2.67 mm^{2}).

The possibility of distinguishing mark, expressed as the equivalent area of discernment (S) with the factor of resolution in width (S=S/CRS) when comparing figures (figa and figd), shown in table (five lines 1 and 8 above). Figure 5, Fig.6, Fig.7 presents examples of shapes with different resolution across the width of the sign and the results of the values of the coefficients of the resolution listed in the table.

From these tables it is seen that the greater the resolution of the sign, the farther are separated from each other positional display elements, the smaller the coefficient resolution. The value of the equivalent area of discernment (Sp) each sign is less than the equivalent area of detection of the same sign on the coefficient of the resolution of the sign (S=S/Krassen). The ratio of the resolution tends to 1 at a sufficiently large distance between the positional elements of the mark (file, file, file - the bottom row of the tables).

In this case, the value of the equivalent area distinguishing mark is committed to the magnitude of the equivalent area of the detection mark (positional elements of the sign does not have any impact on each other).

Likewise determined coefficient is ecient resolution (CRS=c/d) height of sign (figd, file).

When determining the magnitude of the coefficient resolution height of the sign, with one horizontal positional element (figd), measured the distance of the thickness of the positional element to the border height of the sign (s) and measure the distance (d) period (fige) between the two horizontal positional elements, located on the border of the height of the sign.

Quotient, c/d (dimensionless number) can be characterized as the relative magnitude of the resolution of the sign or the magnitude of the coefficient resolution character height (CRS=c/d). The greater the value (CRV=c/d), the lower the resolution of the height of the sign.

As a prototype we choose the matrix electroluminescent indicator MEL-1 matrix 27×160 /5 - str/. When forming the 7-position of the digits on the face of the matrix indicator will use the smallest digital semipositone format with the number of point elements, equal 3x5 (figa). Face semipositone characters (figb) correspond fig.8.1. /1 - p.91, 5 string on top of/ or RIS. /1 - p.98, 3 row above/. These figures on a dot matrix display field when it is displayed not have a deviation from the vertical.

For each display sign digital format 3×5 define and tabulate No. 6 (pigv)

1. n - the number that is echnik elements width and height of the sign, respectively;

2. The square format of the sign on 3×5 dot elements, taking into account the gap between them (t=0.25 mm), width and height of the point s=1.15 mm, equal to:

S=(3s+2t)×(5s+4t)=(1.15×3+0.25×2)×(1.15×5+0.25×4)=26.66 mm^{2};

3. Area select the function of the positional elements of the mark (S): S=n×s^{2};

4. the size of the "window" (S), equal to the square format of the sign (S) net area (S) positional elements of marks (S=S-S);

5. the value of the equivalent area of the detection by the formula:

S=(S×S):(S+S);

6. the coefficients of the resolution width for characters 0 and 8 (the linear size of the point s=1.15 mm, the distance between the dot elements t=0.25 mm) is equal to: KRS=a/b, where a=2s+2t, and b=s+2t (Figg).

Cross=a/b-(2s+2t):(s+2t)=(2×1.15+2×0.25):(1.15+2×0.25)=2.80:1.65-1.70 (figv -10 and 2 rows below, column 7);

7. the coefficients of the resolution width of the sign for numbers 1, 2, 3, 5 and 7 (figa and figb), in which the second vertical positional element is absent, relative to which the measured distance b, and the formula will look like this: Cross=a/b=a/a=1, b=A.

In this case, the measured distance (a) from one positional element to the border of the sign (high) and measured the same distance from one positional element to the border of the sign (b=a) in the absence of the second position element.

The absence of the second position the th element of the sign is equivalent to the location of the second position element at a great distance, not affect the distinction between the first position element. And the ratio of the resolution in this case will be equal to CRS=1;

8. the coefficients of the resolution width of the sign for numbers 4, 9 and 6, in which there is no point item left in the bottom half (figures 4 and 9) of the sign and to the right in the upper half (figure 6) sign (Figg - slightly darkened spot elements);

for digits 4 and 9:

A. measured total length (a+a) right lower (second lowest) point of the element and from upper right (second from the top) of the point element to the borders of the sign in the lower and upper halves;

B. measured total length (a+b) from the bottom right (second from the bottom) point of the element to the border of the sign (a), in the absence of a point of the element on the left in the lower half (the second from the bottom) of the sign, and from the right top point of the element to the top (second top), point element (b) to the left in the top half of the sign, if any.

The ratio of the resolution width of the sign is calculated by the formula:

CRS=(a+a):(b+a), where a=2s+2t, and b=s+2t

Cross=2(2s+2t):(s+2t+2s+2t)=2(2×1.15+2×0.25):(1.15+2×0.25+2×1.15+2×0.25)=5.6:4.45=1.26 (FIGU - 6 and 1 line from the bottom, respectively, column 7).

The same value of the coefficient of the resolution width of the sign (Cross=1.26) will be equal and for figures 6 (Figg - 4 line from the bottom, to Lanka 7);

9. the coefficients of resolution height for characters 2, 3, 5, 6, 8 and 9 (high): CRS=c/d where C=2s+2t, and d=s+2t

CRS=(2s+2t):(s+2t)=(2×1.15+2×0.25):(1.15+2×0.025)=2.80:1.65=1.70

(figb- 8, 7, 5, 4, 2, 1 bottom line, respectively, column 8);

10. the value of the coefficient resolution height for the sign 0:

CRS=c*/d*, where s*=4s+4t, and d*-=3s+4t (high)

CRS=(4s+4t):(3s+4t)=(4×1.15+4×0.25):(3×1.15+4×0.25)=5.6:4.45=1.26 (FIGU - 10 the bottom line, column 8);

11. the coefficients of resolution height for characters 4 and 7:

CRS=c/d=1 (d=c);

12. the magnitude of the coefficients resolution height for mark 1:

Crew=1 (this sign is not horizontal positional element);

13. the coefficients of the resolution of each sign (FIGU, column 9).

The value of the coefficient of the resolution of the sign is equal to the product of the coefficient value of the resolution width of the sign on the coefficient resolution height of the sign:

Crossn=CRS×Crew;

14. the value of equivalent area (S=S/Krassen) distinguishing mark (FIGU, column 10). The value of the equivalent area distinguishing mark (S) is less than the equivalent area of the detection mark (S) on the value of the coefficient of the resolution of the sign (Krzn).

The larger the value of the coefficient of solving the ability of the mark,
the greater decreases the value of the equivalent area distinguishing mark in comparison with the size equivalent to the area of detection. When the value of the equivalent area of the detection mark (figure 8), is equal to 6.11 mm^{2}value equivalent to the area of discernment decreased almost 3 times to 2.11 mm^{2}(if Crossn=2.89).

Table No. 6 (pigv) shows that the value of an equivalent area of discernment (S) most semipositone characters less than the amount equivalent to the area of detection (S) on the value of the coefficient of the resolution of the sign. And only the digits 1 and 7, in which the ratio of the resolution of the sign is equal to 1, the value of an equivalent area of discernment equal to the equivalent area detection (S=S).

It is impossible when the style 7-way signs to eliminate the influence of the ratio of the resolution of the sign by the amount equivalent to the area of discernment. Reducing a coefficient value resolution value of the equivalent area of the detection mark is committed to the magnitude of the equivalent area of discernment. But to reduce the coefficient value of resolution at the formation of such characters need to increase the size of the "window" between positional elements. The increase in the area of "open" leads to an increase in the of armata sign.

To each decimal value equivalent to the area of detection (S) would be equal to the equivalent area of discernment (S) without increasing square "window", you must change the shape of characters.

Mark the outline of any decimal places, consisting of point elements shall be represented by not more than one horizontal and one vertical line. Reduction of displayed lines in the signs to the minimum possible number (similar to figures 1 and 7 when semipositive font - figb) will lead to better differentiate between the two. The value of the equivalent area of discernment such figures will be equal to the value equivalent to the square of their detection (FIGU, 3 and 9 rows in the table No. 6). The speed of the identification mark shall be increased.

The size of the "window" (not blacked out point elements) semipositive (figa) digital format 3×5 is one of the constituent parts of the total area of the "window" (S) any decimal places (let's denote it S-f). Not blacked out spot elements of digital format perform the basic function of the square "window": the ability to distinguish between positional elements of the sign as the height and width of the sign. Square "window" digital format (S-f) point delimits elements semipositive sign located on different sides of it. Without it, the display is laid semipositone characters cannot (Figa). But it is this part of the total area of the "window" (S-f), located inside the marks, degrade their discernment when reducing the dimensions of point elements and digital format in General. And the smaller the value of this area, the less digital format characters, the more the value of the coefficient of the resolution of the sign (Krzn). But to exclude this part of the total area of the "window" (S-f) from semipositive format cannot. The magnitude of this part of the total area of the "window" digital format (S-f) do not select the function point elements like the size of the unmanaged (passive) in the formation of characters, remains constant in all displayed characters. These are not blacked out spot elements of digital format in the formation of decimal places to shift control signal with blanking on the luminescence and luminescence on the repayment is not received.

When you reduce the size of this area to reduce size, format oppositely located positional elements of the sign are converging. A higher rate of resolution, decreases the amount equivalent to the area of discernment, perception of the sign deteriorates.

The second part of the total area of the "window" (S) is formed during the formation of the mark from not select the function point elements (S.. circuit semipositive format. This active control is by part (S..), the total area of the "window" (S), each point item which can be displayed or suppressed when forming the sign from the loop semipositive format, depending on the style of the sign. When receiving a control signal at highlighting some part of point elements semipositive format is formed by the area of the contour of the character from the select the function point elements (S.. or S - square positional elements of the sign). At the same time, from another, the remaining part of point elements in digital format, when receiving a control signal for damping formed a square "window" from not select the function point elements (S..). This part (S..) of the total area of the "window" (S) changes its value with the transition from the formation of one sign to another, depending on the shape of the mark.

The third part of the total area of the "window" (S) is the sum of the areas of the spaces between the dot elements (S). It remains constant and unmanaged total square "window".

Thus, the total square "window" in the formation of the sign will be equal to:

S=S-f+S..+S

To build a new digital alphabet, all characters which the amount equivalent to the area of the discovery would be equal to the value equivalent to the area of discernment, it is necessary first of all to deliver what I passive square "window" (S-f) the smallest digital semipositive format 3×5 (not blacked out point elements figa)located inside semipositive format. For this purpose, these passive point elements will supply the control signals for displaying or clearing depending on the style of either sign. When the shift control signal (blanking on the display or display for damping) during the formation of each of these characters point elements (now actively managed) will be included either in the area of the contour of the character from the select the function point elements (S.. or S), or in a square "window" from not select the function point elements (S..).

In this case, the value of the total area of the "window" will consist of quantities do not select the function point elements (S..) and the amount of space between the dot elements (S). The value of passive square "window" semipositive digital format (S-f) in the formation of new characters replaced with the equivalent active (driven) the size of the "window" from not select the function point elements (S..). The digital format 3×5 (figa) takes the form of a matrix of 3×5 (figa). In the new digital format increased the number of actively managed point of items 13 to 15. The increase in the number of active point elements in a digital format 3×5 to format a matrix of 3×5 increased the number of possible digits, helped to create a new digital basic use the t decimal numbers (figb).

In accordance with the mark of decimal places (figb), digital format which is a matrix of 3×5, which all point elements active in the formation from one sign to another sign at each point of the matrix element of the form 3×5 receives control signals on the display and on the damping.

Outline any decimal sign is not more than one vertical and one horizontal line from the select the function point elements. The ratio of the resolution of the sign at all decimal digits at their lowest mark. All digits the same value square circuit sign of select the function point elements (S.. or S) with the same number, equal to 7. The size of the "window" (S=S+S..)equal to the sum of squares between-point elements (S) and magnitude square "window" from the same number do not select the function point elements (S..), all characters are the same. Or the size of the "window" is equal to the difference between the value of the square of the digital format (S) and the value of the square contour sign (S.. or S) select the function point elements (S=S-S).

On Figg, 6th line from the bottom of the table No. 7 shows the calculated values of required parameters of numeric characters. The value of the equivalent area of discernment of decimal places (0 to 9) is conducted is not equivalent to the area of detection (S=S=6.45 mm^{
2}) and 1.7 times higher than the average equivalent area of discernment (S cf.=3.90 mm^{2}) semipositone characters of the same format (FIGU, table No. 6).

To move from a matrix of 3×5 (figa) to the smallest number of point elements of the matrix of 3×3 (pigv) displaying a new digital signs (Figg) does not cause any complications. All point matrix elements of the 3×3 actively participate in shaping the contour of the character from the select the function point elements (S... or S) and square "window" from not select the function point elements (S..). The control signals on the display and on the damping in the process of formation of decimal places go on all point elements of the matrix of 3×3 (digital format 3×3) depending on their style. The format of a matrix of 3×5 reduced to 3×3, i.e. reduced in height 1.7 times. If the average equivalent area of discernment on the figure (S cf.) when forming semipositone signs and digital format 3×5 equal to 3.90 mm^{2}(pigv), average equivalent area of discernment to digital digital alphabet with a constant number of point elements in the mark in digital format 3×3 is almost the same and equal to 3.80 mm^{2}(figd, table No. 7, 6th line from the bottom, column 10). This quantity (S=3.81 mm^{2}) constant at mark each digit having a Central area is deficient in number (n=5) of point elements in any decimal sign.
A constant number of point in the characters in this format reduces the unevenness of brightness of marks and uneven energy consumption in characters, while the style semipositone digits of this value (S cf.) is located within the boundaries of 2.11 mm^{2}- 6.04 mm^{2}(Fig. 8b, table no:6, column 10). Some signs are well distinguishable (figure 1 and 7), and others very poorly (figure 8, 9, 6 and 0). The value of the equivalent area of discernment they range from 2.11 mm^{2}to 3.00 mm^{2}. To identify such figures are already difficult.

The value of equivalent square distinguish between new decimal digits from 0 to 9 with a constant number of point elements in the signs can be increased to the maximum value (S=S:4=15.60:4=3.90 mm^{2}). For this purpose it is necessary to reduce the spacing (t) between the dot elements to 0.10 mm and increase the format of point element to 1.25×1.25 mm^{2}retaining overall size (S=15.60 mm^{2}digital format (figd, table No. 7, 5th line from the bottom, column 10).

The value of the square of the positional elements (S) is equal to the square "window" (S).

If some face semipositone characters (figb - digits 0, 6, 9) and can achieve almost the maximum value is equivalent to the square of their detection (S=6.43 mm^{2}and almost equal to the value S : 4=26.6:4=6.65 mm^{2}), then the coefficient solving is the ability to have these signs, the magnitude of the equivalent area of discernment (S=3.00 mm^{
2}) have significantly lower maximum for the given format (FIGU, table No. 6 - 10, 4 and 1 line from the bottom, respectively).

When reducing the gap between the dot elements in semipositive format value is equivalent to the square of the distinguishing marks will further be reduced by increasing the ratio of resolution.

Thus, changing a habitual semipositive face of decimal places (figb), in which the area of the "open" sign (S-f + S..) limited positional elements (particularly clearly seen in figures 8 and located within the mark when the mark new signs square "window" (S..) do not select the function point elements is located (this can be seen particularly clearly in the new figures 0) with respect to the vertical and horizontal lines of the contour sign (Figg) outside of the sign. When forming any other decimal sign a new alphabet size of the "window" from not select the function point elements (S..) is not limited to two sides of the vertical or horizontal lines of the contour of the sign, i.e. not located between them. It is located outside the path of the sign, and the shape of the sign is located inside the square "window" from not select the function point elements (S..).

It is clearly seen, if we form the characters in the information field of a larger format than the format (fige). is this case a square "window" does not affect the value of the coefficient of the resolution of the token.

Usually when scaling semipositone characters, with the transition, for example, from a digital format 3×5 (figa) to digital format 5×7 (Figi), increases the width and height of the digital format. The thickness of the outline of the character (s) in the formation of characters does not change. The value of the average equivalent area of discernment in the formation of characters increases less than three times (larger digital format and a reduced coefficient resolution of signs) 3.90 mm^{2}to 10.48 mm^{2}(FIGU, table No. 6 and Figl, table 8, respectively).

The dimensions of the information field indicator MEL-1 (27×160) allow to increase the dynamic range of the variation of a quantity equivalent to the area of discernment in the formation of new characters:

1. through the use of the smallest digital format 3×3;

2. due to the smallest factor of resolution at mark new signs;

3. due to the thickness of the outline of the sign.

The value of the equivalent area of the distinguishing characters when scaling them with the transition from digital format 3×3 (pigv) to digital format 9×9 (figs) increases in proportion to the increase in the number of point elements height and width of the digital format and in proportion to the increase in the thickness of the outline of the sign equal to the width of the previous digital form is 3×3.
At this scale the width and height of each positioning element of the digital format 9×9 equal to the width and height of the digital format 3×3. The value of the equivalent area of discernment (S) increased by more than 9 times (with 3.81 mm^{2}to 36.26 mm^{2}) is proportional to the increase in the overall size of the digital format and is proportional to the thickness of the contour sign (Figg, Figg, Figg, table No. 7, lines 6 and 4 below, respectively, column 10).

The value of the equivalent area of the distinguishing characters when scaling them with the transition from digital format 3×3 (Figg - 0) to digital format 9×9 (figs) without changing the contour of the sign increases only in proportion to the increase in the number of point elements height and width of the digital format. The value of the equivalent area of discernment (S) increased in this case only 5 times (with 3.81 mm^{2}to 19.14 mm^{2}- Figg, figs, figd, table No. 7, lines 6 and 2 below, respectively, column 10).

The formation of any decimal places with the increased thickness of the circuit makes it possible to identify the decimal point on the sign of the maturing point of the item that is located in the center of each positional element (Figi). The value of the equivalent area distinguishing mark in this case decreases with 36.26 mm^{2}up at 34.52 mm^{2}(figd, 4 and 3 lines, respectively, column 0,
table No. 7). When forming multiple digits decimal point is detected on the last sign of an integer, after which formed the fractional part.

To increase the range of changes of the equivalent area distinguishing mark, you can use the formation of the mark with a single point item that is located in the center of each positional element sign (FIGC, figd, table No. 7, 1 line). The value of the equivalent area distinguishing mark significantly reduced (S=6.31 mm^{2}). The range of changes in the value of the equivalent area distinguishing mark is increased.

The value of the equivalent area of discernment (S) characters when scaling them with the transition from digital format 9×9 (figs) to digital format 27×27 (figa), with a simultaneous increase in the width of the outline of the sign is equal to the digital format (9×9), increased more than 9 times (36.26 mm^{2}to 331.91 mm^{2}- figd, table No. 7, line 4 from bottom, column 10 and FIGU, table 9, line 20 from bottom, column 11, respectively). The number of all select the function point elements in the formation 5 of the positional elements of any decimal places (figa) is: n=9×9×5=405 (9×9=81 - figa for one positional element). The increase in the equivalent area of discernment in proportion to the increase in the overall size of the digital format and is proportional to the thickness of the outline of the sign.
The value of the equivalent area distinguishing mark maximum for all select the function point elements. Moreover, for each decimal digit from 0 to 9, using a specific digital format, the value of an equivalent area of discernment is one and the same.

Changing the number select the function point elements of the sign, you can adjust the amount equivalent area distinguish it widely. For this present format (9×9) each positional element token that contains a set of five (1-5) independently controlled circuits formats (figb), forming a square. The thickness of the contour of any format (1-5) corresponds to one dot element. The number of point elements (n) in the circuit of each of these formats, respectively (figb) is equal to:

1. n=32 in the circuit of the first format 9×9;

2. n=24 in the circuit of the second format 7×7;

3. n=16 in the circuit of the third format 5×5;

4. n=8 in the circuit of the fourth format 3×3;

5. n=1 - in the circuit of the fifth format 1×1.

Thus, when forming the mark independently managed contours formats are displayed or suppressed in various combinations, changing the thickness and overall size of the positional element, and the value of equivalent square distinguishing mark (Fig).

When not displaying, for example, only the contour of the 5th format 1×1 (figa), located in the center of each positional element (weakly blacked out point item) the number of point elements of the sign on the five-point items will be reduced by 5 (1×5). The value of the equivalent area of discernment when the number of point elements (n=400) in the sign will decrease (FIGU, table 9, line 19 below).

A decrease in the equivalent area distinguishing mark will be detected as not select the function point of the element at each position element. This does not select the function point item on the background select the function of the other elements (figa) can be used as the decimal point in the formation of character.

When not displaying simultaneously contours of the 5th and 4th formats in the center of each positional element (figb) the number of point elements of the sign on the five-point items will be reduced to 45 (n=9×5) from 400 to 365. The value of the equivalent area distinguishing mark will be reduced (Fig. 11b, table 9, line 18 below). Point item (weakly darkened) in the formation of the mark without the decimal point is not displayed.

In the formation of character with the decimal point, this point item will appear on all five positional elements of the mark (figb). The value of the equivalent area distinguishing mark will increase (FIGU, table 9, line 17 from bottom). The increase is equivalent to the square of the distinguishing sign when displaying point element of the 5th format on the background do not select the function point of the contour elements of the 4th format, situated in the immediate vicinity, you can use the TB as decimal point in the formation of character.

Thus, the decimal point on each positional element of the mark can be identified as the maturity point of the contour element consisting of a single point element of the 5th format (figa, Fighe-2H), located in the center of each positional element of the sign and its luminescence (figb-Figg, Fig 12. and - fill). It depends on highlighted point the circuit elements of the 4th format, located in the immediate vicinity, or they are suppressed.

On Fig options presented (figa-fill) on the example of one of the five positional elements of the mark generated when the number select the function point elements that change the value of the equivalent area distinguishing mark. When forming the mark independently managed contours formats that make up each positional element, displayed or suppressed in various combinations, changing the thickness and overall size of the positional element, and the value of equivalent square distinguishing mark. Encoding spatial orientation /5 - p.62/ or coding thickening and overall size of each positional element of the sign leads to a noticeable difference between one version of a visual display of numeric characters from another variant. All necessary formulas to calculate the parameters of the sign shown at 11. The source data is e and the results of calculations in accordance with figa-Figl listed in table No. 9, figv for digits from 0 to 9.

The value of the equivalent area distinguishing mark varies from S=331.91 mm^{2}(figa-FIGU, table 9, line 20 below) to S=56.90 mm^{2}(file-FIGU, table 9, line 11 below).

On Figg shows an example of the possibilities of the formation of character with the least amount equivalent to the area of discernment (S=6.57 mm^{2}- figd, figw, table 9, 12th line from the bottom of the sign, when each positional element of the sign is displayed only one point item in the center of it.

With the reduction of the gap between the point of the indicator elements to t=0.07 mm and a simultaneous increase in linear size of the point element to s=1.32 mm, while maintaining the overall size of the digital format S=1410 mm^{2}you can reach maximum values of equivalent area distinguishing mark when each positional element of the sign shows all point elements.

The maximum value of the equivalent area of differentiation is determined by the formula: S max=S:4=1410 mm^{2}:4=352.50 mm^{2}(FIGU, table 9, line 2 from below) and determined based on the formulas presented figure 11. When detecting the decimal point, the maturity point of the element in the center of each positional element of the sign, the magnitude of the equivalent area decreases (FIGU, that the person No. 9,
1 line).

A clear demonstration of the formation of character when scaling them upwards within a specified digital format allowed by the format of the information field of the indicator shown in Fig. The width and height of the positional element of each subsequent largest overall size of the digital format has steadily increased in proportion to the width and height of the digital format of the previous largest overall size of the digital format.

The value of the equivalent area of the distinguishing characters also increases in proportion to the increase in the overall size of the digital format and the thickness of the outline of the sign equal to the width of the previous largest overall size of the digital format.

With the growth of digital format to increase its functionality. If the smallest digital format 1×1 (figa) it is possible to form only two characters: these are the two numbers 0 and 1 (not displayed or displayed point item), the digital format 3×3 (figb) are formed for ten numeric characters corresponding to the numbers from 0 to 9. Decimal point is formed next to the sign. The value of the equivalent area distinguish each decimal places equal S=3.81 mm^{2}.

On digital format 9×9 (pigv) formed ten numeric characters, with the corresponding numbers from 0 to 9, with the possibility of the formation of the decimal point, detected by maturity point item that is located in the center of each positional element of the mark.

On digital format 27×27 (figa) are formed numeric characters:

1. mode (figa), which uses all point elements of each of the five positional elements (n=9×9×5=405) when forming each of the ten numeric characters corresponding to the numbers 0 to 9 and decimal point, detected by maturity point item that is located in the center of each positional element sign (figa). In this mode, without displaying the decimal point, the value of equivalent area distinguishing character maximum;

2. mode (figb-fill), in which when forming the ten numeric characters corresponding to the numbers 0 to 9 can be sold or displayed in various combinations contours formats (1-5) of each positional element of the sign. The formation of characters with varying number of point elements in the characters (with the changing value of the equivalent area distinguish them) has the following objectives: 1. savings in energy consumption; 2. tracking the change of the measured parameter of the object outside the operating mode (automatic control systems). The controlled object can be created emergency situation or when increasing, or when smart is against the measured value of the parameter object.

FIELD: information technology.

SUBSTANCE: in the matrix display, digital format position elements are distributed on 9x9, 7x7, 5x5, 3x3, 1x1 format loops, illumination or black out of which causes change in the number of point elements therein, while maintaining, when formatting digital characters from 0 to 9, constancy of the number of point elements therein, which corresponds to the changed number of displayed point elements in the format loops, and the decimal point is displayed on the character either by blacking out or illuminating the 1x1 format loop depending on whether it is illuminated or blacked out when forming characters.

EFFECT: reduced power consumption irregularities from character to character owing to providing equal surface area of illuminated point elements of a character.
