The level of technology

The present invention relates to the improvement of the diffraction display (reflective or translucent), in which each pixel emits the entire range of the diffracted wavelengths (for example, the entire color range) using the new diffraction techniques.

A large number of graphic displays, which are used, for example, a bimorph piezoelectric elements and their equivalents. Bimorph element is a device consisting of two strips of piezoelectric film, which are connected together and which have electrodes that apply to film the electric field of the desired polarity, causing electrostriction effect. This electrostriction effect may manifest as a flat extension or reduction, or as a deviation from the plane of one end of the film when attaching the opposite end.

In U.S. patent No. 4331972 proposed light shutter including a pair of elements of transparent material, each of which contains a periodic dip Klenow lattice, these grills are located opposite each other so that their strokes are parallel. In this patent, such a light barrier is called the double diffraction grating. Passing the light beam through the double diffraction grating depends on the relative position of the pair of gratings in the direction perpendicular to the lines of the grating. One of the gratings can be made by embossing on the piezoelectric PVDF film and move when the application thereto of an electrical voltage. As a result, in response to an electrical signal one bar can move relative to the other to control the zero diffraction or light transmission in the range from full light delay until its full bandwidth, to provide any desired intermediate level of bandwidth. For the formation of three different colors needed to create a color display, i.e. blue, red and yellow colors, using three different superimposed on each shutter of the double diffraction gratings.

In U.S. patent No. 5067829 serves to control the light beams pass through the optically transparent elastic material, which is bent under the influence of an electric voltage, and this bending or deformation leads to a change in the angle at which the light beam crosses the surface of the optical is Ki transparent layers.

In U.S. patent No. 5052777 bimorph element is used as a circuit breaker intended for the transmission or delay incident light. Such bimorph breakers allow you to transmit light, for example, transmitted through the optical fiber, through the bimorph light gates to the observer to create graphic images.

In U.S. patent No. 4274101 described laser recording device that uses the piezoelectric bimorph vibrator, changing focal length.

In U.S. patent No. 5126836 offers a television display, in which a white light source emits a beam incident on the set of dichroic mirrors which split the beam into three beam primary colors. Then these primary rays are reflected on the three deformable reflecting surface, which may be piezoelectric crystals and which again reflect the rays through cracks in non-reflective surface, thereby modulating the intensity of the rays. In U.S. patent No. 4415228 offered bimorph light barrier, similar to that described in U.S. patent No. 4234245.

Other suggestions include an article Stein, et al. "A Display Based on Switchable Zero Order Diffraction Grating Light Valves", Advances in Display Technology V, SPI vol. 526, 105-112 (1985), which offers a flat display that uses a matrix of linearly addressable optical shutters, lighted from the rear article the Rhone by partially collimated source. The main pixel element of the display is an optical switch, which is based on diffraction zero order in two Shustorovich translucent phase diffraction gratings. Passing modulate light by the mechanical movement of one grating relative to the other half of the grating pitch. For this purpose bimorph element.

And, finally, there is the work of Gale et al., "Diffractive Diffusers for Display Application", Current Developments in Optical Engineering and Diffraction Phenomena, SPIE vol. 679, 165-168 (1986), which offers diffractive optical diffusers for applications associated with the creation of displays, and diffusers can be made using the methods of laser recording.

The above methods allow you to create graphic displays, however, significantly improved ways of creating such displays are disclosed in U.S. patent No. 5613022. By moving the diffraction grating is a technical solution can be used to create graphical displays in which each pixel is able to form all the colors. To improve visual perception pixel can light diffusing panel or surface for displaying the image.

Although this diffraction technique allows to increase the efficiency of graphical displays, there is still a real need for an additional method is x, to make such a diffraction displays economical and practical, especially for large-scale production.

The invention

The present invention is directed to improvement of the diffraction display designed for graphic images, and other similar displays. In General, the new embodiment of the display based on the use of holographic diffraction pattern (hologram)that is placed on the magnet or the bearing element, and a coil fed by an electric current, which is in magnetic engagement with the specified magnet and can lead magnet in motion. When turning the holographic diffraction pattern dragirovaniya light creates a graphic image.

Another new embodiment of the display based on the use of a compound of the rotary element (FRE - Faceted Rotatable Element)containing a matrix of facets, each of which carries a diffraction grating, and a source to which the supply power to rotate the compound rotary element from a position of rest in the surveillance state. Turn compound rotary element creates an image due to deviation of the light diffraction gratings.

In one of the configurations compound rotary element is an essentially flat to who's window plate with plenty of support along its outer edge, on each of the pillars has a diffraction grating. However, it is preferable that all of the diffraction grating in the matrix had a different period (pitch) of the lattice, were made in the form of holographic diffraction gratings and were located on the surface of the plate. Can be used and other configurations, which are characterized by lower weight, higher speed of rotation, less acceleration and deceleration, which ensures a quick change of color of each pixel. Turn compound the rotary element can be implemented, for example, by using a stepper motor or linear actuator.

Detailed description of the invention

A unique method of forming a graphic image has been disclosed in U.S. patent No. 5613022. In this method, diffraction grating, which is located on electroactive or magnetic tape, is connected with a source of energy, which power can cause the film to move. what if the diffraction grating is illuminated by the light of a broad spectral range, it rejects the light of a certain color at a certain angle. Moving the film carrier of the diffraction pattern, change the angle of incidence of light on a diffraction grating. This will cause the beam deviating a given angle, will have a different wavelength. With a wide spectral range of the source of visible light (although the present invention is equally applicable to ultraviolet and infrared radiation), you can force the pixel to reflect different colours, in particular red, green and blue, depending on the rotation angle of the diffraction grating.

To achieve color uniformity and a wide field-of-view this lattice must be a hologram, for example, formed on a glass plate, a film, etc. the Color of the rejected beam is determined by the equation lattice

where

λ - wavelength diffracted light (μm);

d period (pitch) of the lattice (μm);

ι - the angle of incidence relative to the normal to the plate (degrees);

δ is the diffraction angle relative to the normal to the plate (degrees). When fixed δ and d wavelength change ι.

Many embodiments of the displacement of the diffraction grating described in U.S. patent No. 5613022. One option involves applying voltage to the piezoelectric m is a material predetermined, attached to the diffraction grating, resulting in a material bends, changing the effective period of the diffraction grating. The deviation of the film it proportionally submitted voltage. In other embodiments, magnets and coils that provide the deviation of the diffraction grating of the electromagnetic means. Each of the options using the magnetic means is described in U.S. patent No. 5613022, includes a stationary permanent magnets and rotating the coil is attached to the diffraction grating. The interaction of the fields of the permanent magnets and the magnetic field created by the coil generates a force that makes you turn the coil, and hence diffraction grating.

Although the devices described in U.S. patent No. 5613022, can be considered suitable for most commercial applications, in engineering there is always a tendency of further development of the device in the direction of increasing their practicality and effectiveness. When testing the device, which used a fixed coil and a movable magnetic element bearing a diffraction grating, were obtained unexpected results. It can be assumed that the use of a fixed coil and a moving magnet instead of a fixed magnet and a movable coil will give the same result. However, when use is the so called rolling magnet were achieved unexpected and useful results, including less weight in relation to the new rotational torque and less power loss, less variation of the parameters of the material of the hinges from the point of view of rigidity of the spring and conductivity, reducing the problems associated with the management of product quality, lower production costs.

Figure 1 shows a top view of the pixel 90, including an improved movable magnet. There is a diffraction grating 100, which may be a holographic film. Diffraction grating 100 is attached to the magnetic element, which is a permanent magnet (item 120 in figure 2 and 3). Diffraction grating 100 may be directly connected to the magnet 120 or, alternatively, the diffraction grating 100 and the magnet 120 may be separately attached to the additional element for connecting them with each other. The magnet 120 lies on the axis 140, which is made of a ferromagnetic material and, therefore, attracts the magnet 120 and holds it in place, while allowing for the deviation with respect to the axis 140. Near the axis 140, or as part of, or in connection with it, is a current-carrying wire 160, which is connected with the field effect transistor 170. Essentially, the magnet 120 and the coil 160 are in magnetic interaction with each other.

When the wire 160 of current flow creates a magnetic field, is AutoRAE acts on the magnet 120. Since the magnet 120 is not fixed, the force created by the current in the wire 160, causes the magnet 120 and the associated diffraction grating 100 to rotate about the axis 140.

The direction of rotation of the magnet 120 and the corresponding diffraction grating about an axis 140 depends on the direction of the magnetic field created by the magnet 120, and the current direction, the current in the wire 160. Changing the direction of the current in the wire 160 changes the direction of the generated force that causes the magnet to rotate in the opposite direction. Wire 160 can have many turns, but for efficiency, it is preferable that the coil contained one round. To prevent exposure fields generated by neighboring pixels or external sources (the so-called crosstalk), there is a magnetic screen 260. This screen can be performed, for example, of steel SAE 1010. As it is clear to experts in the art of the possible alternative constructions of pairs consisting of a magnet 120 and the coil 160 that is designed to move the magnet. Several illustrative configurations are described in detail below.

On figa-2C shows how the magnet 120 is rotated to two different positions. The numbers are stored position, shown in figure 1. On figa magnet 120 is in its original position perpendicular to the axis 14, as indicated by the dashed line 180. When the wire 160 current flows in the direction shown in figure 1, the magnet 120 is rotated from the initial position at an angle of θ₁in the position depicted in FIGU. When changing the polarity of the current flowing through the wire 160, on the opposite magnet 120 will turn on angle θ₂in the opposite direction, as shown in figs. In the General case, to create a full-color pixel magnet to rotate only around 8 degrees in either direction.

Figure 1 shows the limiters 200 and 210, which prevent rotation of the magnet 120 at the desired limits. To show the limiter 210, a portion of the magnet 120 in the drawing cut. The limiter 210 may include a capacitive probe or sensor (not shown), for example containing aluminized Mylar (Mylar®), which is located below the magnet 120 and specifies the position of the magnet 120. As soon as the magnet moves in the desired position, it is held in place due to the magnetic field surrounding the ferromagnetic pins 220 and 240. These pins magnet 120 can be held in place with a small current through the wire 160 or even in the absence of such current.

Figure 3 shows a side view of the pixel shown in figure 1, and the connection of the above elements to the circuit Board. Stored symbols shown in Fig.. Printed circuit Board 280 is grounded plane 300 and the bus 320 positive voltage. Field-effect transistor 170 are sequentially connected to the conductor 160, the grounding connector 360 and the connector 340 positive voltage (Fig 1), which are connected to the ground reference plane 300 and the positive bus voltage respectively. Similarly, the capacitive sensor located on the limiter 210 is connected to the ground plane 300 at point 400 and bus 320 positive voltage at point 380. The connection elements to the circuit Board 280 is illustrative and does not limit the scope of the present invention, as professionals it is clear that you can use and other structures.

On figa-4F shows the other structure of the magnetic element. On figa shows the configuration used in figure 1, in which the diffraction grating 500 is directly attached to the permanent magnet 502. For ease of manufacture between the magnet 502 and the diffraction grating 500 may be placed bearing element 504, as shown in figv.

In the two previous designs used a single magnet, the size of which coincided with dimensions held a diffraction grating and a bearing element, if such there were. You can use the magnet is smaller. In addition, when using multiple coils is you can use different configurations with multiple permanent magnets, located in different places relative to the diffraction grating. The magnetic element can also be made in the form of permanent magnets formed of discrete particles dispersed throughout the supporting element or embedded in it, with any desired concentration. On figs-4E for illustration shows several possible designs of the magnet. In each of these drawings, the position 506 denotes a permanent magnet, and the position 508 and 510 respectively denote diffraction grating and a supporting member. In these drawings, the supporting member 510 has a rectangular shape and has an upper surface 520, the bottom surface 522, the leading edge 524 and the rear edge 526. However, the description of the rectangular support member 510 is only illustrative and does not limit the scope of the invention, since the geometry of the bearing member 510 can be changed. When using multiple magnets and multiple coils interaction of the resulting magnetic field may differ from those described in connection with figure 1, therefore, may require some modification of this system. However, on the basis of the solutions shown in figure 1, with appropriate modification specialists can develop a unique configuration and thus to benefit from the use of additional driving forces to achieve specific EF is known.

When developing options for performing the rolling magnet electromagnetic concepts as disclosed in U.S. patent No. 5613022, it was discovered that the unique use of diffraction gratings to create graphic images can be processed in a different way. Although this option is similar to the approach opened in U.S. patent No. 5613022, you can get significant design advantages. These advantages can be realized by using compound rotary element intended for deflection of one of the few selected colors by diffraction in the direction of the observer when illuminated with broadband light source at a certain angle. Facet located on the swivel base or element, is an area or space containing a diffraction grating with a certain period, which in the light of its broadband light source rejects the light of a certain color in the direction of the observer. Matrix facets can be formed on the compound rotary element, forming a matrix of diffraction gratings, each of which can have its own, different from others, period, all of the elements of the matrix of diffraction gratings may be located in close proximity to each other or can be spatially separated, and it is possible to use a matrix of holographic diffraction gratings, where the facet matrix superimposed on each other. However, in the simplest embodiment, the present invention compound rotary element may have on its surface a single diffraction grating, with each change of position of the compound rotary element represents some facet. Specialist in the art it is clear that there are many ways of practical realization of the compound of the rotary element. The rotary element may represent, for example, the plate having a surface and outer edge. The plate is connected with an energy source, such as a linear actuator or stepper motor, which is operated by the rotation of the plate. On the surface of the plate may be located one diffraction grating or matrix of diffraction gratings, each element of this matrix is characterized by its period lattice or matrix superimposed on each holographic diffraction gratings; or, alternatively, on the outer edge of the plate can be positioned supports, each of which bears a diffraction grating. Some of the possible structures of compound rotary element details shown on the following drawings. However, they also serve only for illustration and do not limit the scope of the present invention.

Although veneers can be placed along or across a compound rotary element is random, the position of each facet inside the matrix is known. For example, the position of each facet can be stored in the microprocessor memory. Since the position of each facet in the matrix is known, faceted rotatable element can be rotated so that the light source was illuminated by the selected facet, providing diffraction beams of a certain specified color.

Figure 5 facet rotating element having a matrix of facets in the form of supports located on the outer edge, illuminated by a broadband light source. Compound rotary element, indicated generally by the position 600, has a surface portion 602 and the carrier portion 604. Surface portion 602 consists of a matrix of facets (faces) 606a-606f, each of which is a diffraction grating. These gratings provide diffraction of light coming from the broadband source 622. The length of each facet exceeds the length located therein a diffraction grating, therefore, between adjacent diffraction gratings have the space, corresponding to the resting position, such as indicated by the position 621. Each resting position can correspond to a zero position or it can be used to create a background color when no image is. Each of the diffraction gratings 608, 610, 612, 614, 616 and 618 has a unique lattice period, so that light of a certain color, say no grating was visible to the observer at position 620. Compound rotary element 600 is able to rotate about an axis perpendicular to the surface supporting part 604, and this axis may pass through its center of gravity near the edge, through the center or at any other desired location. The position of the axis of rotation, for example as shown at position 624, partly depends on the geometry and design of the bearing portion 604. Turn compound rotary element 600 may occur clockwise or counterclockwise, but the most effective is the rotation in either direction relative to its original position.

Compound rotary element 600 is initially in a resting position. From this starting position compound rotary element 600 is rotated in a surveillance state, when the diffraction grating is located at the origin - in the 626. Figure 5 diffraction grating 614 is located at position 626, so dragirovaniya light of a certain color is visible to the eye 620 observer. This light can be, for example, blue. So in the eyes 620 observer got the light of another color, faceted rotary element 600 is turned from one position observation is Oia, through the rest position, to another position observations. Since each diffraction grating has its unique lattice period, falling from a source 622, the light will be deflected at different angles corresponding to particular colors. Light, dragirovaniya in the direction of the observer bars 616, located on the facet I may be green, while light, dragirovaniya grating 618 on the facet 606f, may be red. The position of the facets relative to the position 626 determines the angle of rotation corresponding to each color. To eyes 620 observer saw the green light, compound rotary element 600 turn on angle θ₁. To eyes 620 observer saw the red light, compound rotary element 600 turn on angle θ₂and so the Number of discrete colors available for the graphic image, is determined by the number of facets and the corresponding diffraction gratings located on the upper part of the compound rotary element.

As shown in figa-6E, to create a compound rotary element for any specific options for performing display can be used in different modifications of the supporting part and facet of the surface. On figa-6E supporting part and the surface part indicated generally items 700 and 702 are appropriate to estwenno. On figa depicted essentially flat round plate 704 having a facet in the form of supports 706a-706d, which protrude from its outer edge. Diffraction grating, for example of photoresist (holographic diffraction grating), is located on the outer end of each support 706a-706d. Using a round plate, such as indicated by the position 704, it is most natural to place the rotary axis so that it passes through the center of the plate 708. Alternatively, as a supporting part can be used only part of the circle, as shown in figv, where the faceted surface portion passes through the outer perimeter. When using a less robust construction compound rotatable element can be rotated faster and at lower cost energy needed to start and finish a turn from one grating to another. In this configuration, the most effective location for the axis of rotation is the center of gravity. To reduce the time of rotation in the desired position monitoring and to improve efficiency by reducing the mass of the compound rotary element of the specialists in the art can use a variety of structures. Similarly, the number of poles or the number of diffraction gratings arranged on each support, m which may vary in accordance with the purpose of the display.

Alternatively, compound rotary element may have a lattice or mesh carrier portion, as shown by the position 710 to fig.6D. In addition, the supporting part may have a hollow Central portion 712, and the surface part can be supported by the ends of the support rods 714 and 716, as shown in figs. Although described supporting part compound rotary element was round or represented a sector of a circle, five shown that the bearing part can be in the form of a polygon. The carrier part can be designed in any configuration that is able to rotate around its axis and to bear faceted surface part. Supporting part 700, shown in FIGU-6TH may, for example, to carry the faceted surface of the part shown in figure 5, or may include veneers, including supports, as figa.

7 shows compound rotary element together with some common elements of the display. Compound rotary element 720 consists of a round generally plate 722 with the outer edge 724 and the surface 726. Although the depicted compound rotary element in the whole round, to meet other design requirements for the display can be used in another form. The shape of the rotating element can also be selected based on maximizing the density of pixels. Continuous DEFRA the traditional grille is located on the surface 726. Diffraction grating 728 has three facet 730, 732 and 734, each associated with a particular color, visible to the observer. When turning one of the facets in the surveillance state in the same way as described in connection with figure 5, light from a broadband source is deflected in the eye of the observer, and the observer sees the color selected. It is clear that many facets, located on the surface of the plate can also be formed using a variety of diffraction gratings. In addition, to improve the effectiveness of a specific color can be duplicated by placing more than one diffraction grating with the same period on the plate surface. The presence of multiple areas of the same color can reduce the time required to rotate the plate in position observations to demonstrate the desired color.

Although the matrix of the facets can be implemented as a set of bearings located on the outer edge of the plate, or in the form of a matrix of diffraction gratings, each element of which has its own, different from others, the lattice period, another approach is the imposition of facets each other using holography. The matrix of facets are put on a single photographic film, each facet has an angular orientation, i.e. the offset from the other. Thus, is formed such GoLoG officesa film, when a predetermined position compound rotary element 720 relative to the light source toward the observer or sensor receives light of a certain color. For example, using a single holographic element, or pixel, you can play red, blue and green. When turning plate 722, for example, on 2° relative to the original position 0°incident light dirigeret and in the direction of the observer is transmitted blue color. When turning plate 722 to another position, for example on 9° from its original position, the observer sees the color green. Finally, when the rotation plate, for example, on 17° from its initial position, the observer sees the color red. Using holographic overlay on the surface of the plate a greater number of facets with different predetermined periods of the diffraction grating, you can create other colors (i.e. wavelengths, both visible and ultraviolet and infrared ranges). Similarly, other colors (wavelengths) can be obtained by oscillation plate 722 between the two diffraction gratings, i.e. between the two colors, with such frequency that the observer will perceive it as some third color.

As mentioned in connection with figure 5 and 6, the matrix of facets are located on the compound rotary element, formed by many difrac the ionic lattices. However, in the simplest embodiment, the compound rotary element with a matrix of facets may constitute a diffraction grating. This compound rotary element shown in figa-C. On figa shown facet rotary element 910 having the above described configuration, and a broadband source of light 912. Compound rotary element 910 is in a fixed position relative to the source light 912, as shown in figa-9C. Item 914 observation is in a fixed location relative to the compound rotary element 910.

When the selected facet facet rotary element 910 is in the position of observation, the observer located at point 914 observation, sees the color of the created compound rotary element 910. When turning the facet between the rest position and the position of the observation, i.e., when turning the compound rotary element 910, the observer 914 on the choice of showing a separate color.

For the formation of these different selected colors, or rays, compound rotary element 910 is made in the form of a plate or disk 913 and one holographic diffraction grating 916, which has a constant period 918 lattice. Diffraction grating 916 is located on the disk surface 913. Preferably, the diffraction grating 916 was a holographic Defrag the ionic lattice. White light 920 from source 912 falls on the surface of the compound rotary element 910, and the grating 916 generates a range 922, or a variety of colors. For the purpose of illustration is shown that the spectrum 922 includes rays of three colors: 924, 926 and 928. In fact, the spectrum 922 includes many colors. The spectrum of diffracted light and the bandwidth of each color is determined by the period 918 grid.

Although usually grating 916 creates many colors, the observer in the 914 observations at each moment in time one sees color. For example, on figa compound rotary element 910 is shown in the initial position, indicated by line 920. In this initial position the observer 914 sees, for example, green color. When turning the compound rotary element from the starting position into the second position as shown in figv in paragraph 914 observations visible second color. For example, when turning the compound rotary element 910 7° relative to the original position, as shown by the arrow 932 going on between the lines 930 and 934, the spectrum of the 922 will be shifted so that paragraph 914 will be visible color 928. For example, it may be red. As shown in figs, compound rotary element 910 may be rotated so that shows a third color, for example when turning on 8° in the opposite direction, as indicated by the arrow 936, going between the similar position 930 and the third position 938. This third color may be, for example, blue.

Each angular position of the compound rotary element 910 represents some facet in each position in the direction of the observer in paragraph 914 deviates the light of the selected color. As in the previously described versions of the invention, when the facet is at the position at which the observer sees a certain color, this facet is in the surveillance state. If the facet is not in the position in which the observer sees any color, this facet is in the resting position. Thus, figa facet corresponding to green color, is a surveillance state. The other two facet facet rotary element 910, i.e. correspond to the red and blue colors, are both in the resting position. On FIGU, facet corresponding to the red color, is a surveillance state, and figs in the surveillance state is the facet corresponding to the blue color.

If the observer is located properly, for example in paragraph 914 on Figo, he is able to see all the colors for selection forms a compound rotary element. The dimensions of the physical realm, where all colors can be seen individually vary depending on the width of each color band. As mentioned above, the spectral range of di is rigirous light and the width of the strip, corresponding to each color is determined by the period of the diffraction grating. The more colors is formed and, thus, the narrower the bandwidth corresponding to each color, the less physical area from which the observer can see all the colors. So, if compound rotary element, such as shown in figa, rotate too far from the original position in either direction, the observer 914 will not see any color.

On figa-8C schematically shows several mechanisms, suitable for compound rotation of the rotary element. On figa compound rotary element, such as described in connection with figa, is connected with the stepper motor. Stepper motor 800 contains the spindle 802 connected to the center of a circular plate 804. The controller 806, controlled by a microprocessor, ensures the rotation of the spindle 802 and connected with it a plate 804 to a specified number of steps clockwise and/or counterclockwise. At each step, the plate can be rotated from a position of rest in the surveillance state, or from one position observation to another, the plate passes through the rest position. The resolution of the stepper motor should at least be equal to the number of diffraction gratings located on the facet surface. When using compound povorotnoj the item stepper motor eliminates the need for position sensors used, for example, in an embodiment of the invention with a movable magnet. The microprocessor can store information about the position of the compound rotary elements, tracking the number of steps in each direction. In addition to the stepper motor, you can use the source of the driving force, capable of converting linear motion into rotational motion.

On FIGU plate 808 is connected to the linear actuator 810. Similarly to the stepper motor linear actuator 810 is controlled by the microprocessor 816. The translational movement of the rod 818 is converted into rotational movement in a known manner, for example by means of a pulley 812 installed between the axis 813, about which rotates the plate, and a nut 814. Another conventional method of converting linear motion into rotational illustrated in figs and consists in connecting the linear actuator plate 820 822 having a curved device. For the implementation of rotational motion of the rod 824 linear actuator 820 is connected to the plate 822 pin 826 located in the gap 828. When the rotation of the linear actuator relative to the point 830 and the moving pin 826 inside cracks 828 plate rotates in the direction of the arrow 832. If risperidal enough, the linear actuator can be mounted at point 830. Specialists and other known methods of implementing rotational movement compound rotary element of circular or other shape.

Let's go back to 7. When the image is created as described above it is possible to use known elements to create a graphic display and similar devices. If compound rotary element is made of a transparent material, the light source can be placed behind the compound rotary element at position 336 with the formation of the translucent display. Alternatively, if the compound rotary element 720 is made of reflective material, the light source can be placed at position 338 with the formation of the reflective display. How to create both translucent and reflective displays are described in detail in U.S. patent No. 5613022. To display any type of image created using faceted rotary element 720 can be focused using a lens (not shown) directly on the light-diffusing element, such as shown by position 340. Since the distance between these elements can be small, thin displays. To create larger images require more space between these elements that you can insert between projectio is a great device, for example indicated by the position 342. Such projection devices are known and can be easily integrated into the display to implement unique methods of forming the image.
