The technical field

The invention relates to selective coverage areas of a display for an electronic device. In particular, although not exclusively, the invention is particularly advantageous for reducing the power consumption of a battery in portable electronic devices, due to the lighting displays.

Prior art

Currently, many portable electronic devices such as handheld computers, personal digital assistants (PDAs), and mobile telecommunications devices, such as cordless phones, have color displays, often in the form of a liquid crystal display (LCD, LCD). Such color displays become commonplace and will probably replace the black-and-white displays and displays with a grayscale image.

However, one of the problems of color displays is that they usually consume a higher current from the battery than the display of black-and-white and grayscale image, thereby reducing the battery life.

Another problem with color displays, relates to lighting displays. Unlike black-and-white displays and the halftone image color displays can be viewed clearly and conveniently only with the backlighting of the display. In the absence of illumination provided by the backlight, the display may be difficult to read, and displayed the Board does not look attractive. In addition, the lighting color displays not only required in a dark environment, but in normal daylight.

Some portable electronic devices for a user, it is possible to set the timeout period for the background light (backlight) or the duration of lighting of the background light (illumination). Therefore, as color displays require light background light for convenient and attracts the attention of the viewer, the user can set the duration of the lighting of the background light or waiting period for background light (illumination) of equal length, which is sufficient to view the displayed information.

However, for many portable electronic devices, such as radiotelephones, the user cannot set the timeout period for a background light or the duration of lighting of the background light. Instead, the timeout period for a background light or the duration of lighting of the background light should be installed during manufacture of the device and will be applied to the entire illumination regarding the state of the display regardless of the display information. This is usually done for the sake of simplicity and integrity (mutual consistency) design. Because of changes to the amount and type of information that can be displayed in the predefined duration of the lighting of the background light corresponds to an average time required to view the information displayed on the display. Therefore, the duration of lighting is often too long when viewing color images containing the minimum information, such as inactive image or short text messages, leading to unnecessary and undesirable reduction of battery life.

One attempt to solve this problem uses the inclusion in the portable electronic device module count, which counts the number of characters that should be displayed. Module lighting control regulates the duration of illumination provided by the backlight according to the number of characters by reference to the reference table of period lighting. For example, if you should be displayed from 1 to 100 characters, the lighting can provide a background light for 30 seconds. If you should be displayed from 101 to 150 characters, the lighting can provide a background light for 45 seconds. The informational table also includes pre-set periods of illumination, which depend on the application being used on a portable electronic device. For example, if the device is used for a telephone call, period lighting, the background light can be set to 30 seconds. If the device is used to apply in order to perform the recording, the period of illumination of the background light can be set to 45 seconds. Period lighting background light (backlight) can also be pre-installed and displayed according to the number of characters used by the application.

Although the above diagram the character count and/or dependent application period lighting several reduce unnecessary use of the battery, these schemes are not sensitive to the importance or other property of the displayed information. For example, if the period of coverage depends on the number of displayed characters and displays a short but important message, such as a missed message call, the display may be illuminated only during a short period, leading to skipping of the message call. Similarly, if the device is in a state of use of the application for which pre-installed lighting period is relatively short, and displays important information, such as an icon (icon) of an incoming message, the period of coverage may be insufficient to attract the user's attention to important information. Therefore, the period of illumination of the background light of these schemes do not take into account the context of the displayed information.

Another disadvantage in the lighting of the displays of portable electronic devices such as radiotelephones conclusion is moved in what once required the lighting of the background light, all elements of the lighting used for illumination, which are often light-emitting diodes (LED), are activated, and the entire display is illuminated, even if there is only a small amount of information such as icons or short text messages to be viewed. It also leads to unnecessary and unwanted decrease battery life, especially with the current trend of large screen displays in portable electronic devices.

Accordingly, there is a need in one or more ways of lighting the background light to illuminate the displays of portable electronic devices, which take into account the type and amount of information to be displayed and which can preserve battery life.

Detailed description the preferred option of carrying out the invention

In the drawings similar digital signs are used to indicate similar elements in all the drawings.

With reference to figure 1 illustrates the portable electronic device in the form of the apparatus 1 containing module 2 RF transmission connected to be connected to the processor 3. Input interface in the form of a display 5 and the keypad 6 is also connected so as to be connected to the processor 3.

The processor 3 includes an encoder/decoder 11 with the corresponding read-only memory (ROM, ROM) 12 storing data for encoding and decoding voice or other signals that may be transmitted or received by the apparatus 1. The CPU 3 also includes a microprocessor 13, which is connected in the usual bus 17 data and addresses to the encoder/decoder 11 and is connected with a ROM 14 characters (ROM), random access memory (RAM, RAM) 4, a static programmable memory 16 and a removable SIM module 18 (subscriber identity module). Static programmable memory 16 and the SIM module 18 each can store, among other things, the selected incoming text messages and database TDb data of the telephone book.

The microprocessor 13 has ports for connection to auxiliary is part of the keyboard 6, the display 5 and the module 15 alerts, which typically contains a speaker, a motor of the vibrator and the associated control circuit. ROM 14 characters stores code for decoding or encoding text messages that may be received by the transmission device 2, entered with the keypad 6. In this embodiment, the ROM 14 characters also stores operating code (OC) for the microprocessor 13 and the code to perform the methods as described below with reference to figure 2-7.

Module 2 RF transmission is a combined receiver and transmitter having a transmitting antenna 7. This module 2 transmit transceiver has 8 connected to the antenna 7 via the amplifier 9 radio frequency. The transceiver 8 is also connected to the combined modulator/demodulator 10, which connects the module 2 transmit to the processor 3.

With reference to figure 2, the microprocessor 13 performs various applications 19, such as application call application alerts (alarms / reminders and application of short message service (SMS). Software application 19 United so as to be in communication with a user interface (UI, UI) and the module 20 controls the display module 21 lighting control. Module 20 display control and PI is also connected in such a way as to be in communication with the module 21 lighting control.

the Module 20 display control and PI is connected through the port 22 of the microprocessor 13 to the circuit of the display in the form of circuit 23 controls the liquid crystal display (LCD). Scheme 23 LCD control connected to the display 5, and controls the activation and deactivation of the display 5 to display on the display 5. Module 21 lighting control is connected through port 25 of the microprocessor 13 to the control circuit of the lighting elements in the form of an integrated circuit (IC) 26 control LEDs. Integrated circuit 26 controls the LEDs connected to the elements 27 lighting in the form of LEDs via the bus 28 of the control signals and line 28a of the control signals.

With links to figa-3C, in one embodiment, provided two element 27 lighting in the form of LEDs U1, U2, located near the upper part 29 of the display 5, the two elements 27 lighting in the form of LEDs B1, B2 located near the base (bottom) 30 display 5, the two elements 27 lighting in the form of LEDs L1, L2, located near the left part 31 of the display 5, and the two elements 27 lighting in the form of LEDs R1, R2, located near the right part 32 of the display 5. Each element 27 lighting provides background light (backlight) display 5, and each element 27 lighting can be individually activated and deactivated.

With reference to table 37 display, shown in figure 4, as in the conventional portable electronic devices, the entire display area, marked as region A of the display 5 may be lighting the Jena, activating all of the elements 27 lighting, adjacent (nearby) display 5. The whole area can be covered within a predetermined time period Z, for example, 15 seconds.

However, in accordance with the present invention, Figa-3C show the many different ways the selective illumination of the display area 5, which is described below with reference to table 37 display, shown in figure 4.

With links to figa, activation of the integrated circuit 26 controls the LEDs of the LEDs L1, R1, U1 and U2 selectively covers essentially the upper half of the display 5, identified as region B. similarly, activation of the integrated circuit 26 controls the LEDs of the led L2, R2, B1 and B2 selectively covers essentially the bottom half of the display 5, shown as region C. Region B, and C each can be covered within a predetermined time period Y, for example 8 seconds. Period Y lighting is shorter than the period of Z for the area And, because of the size of areas B and C relative to the area A. There is a possibility that there will be less information in smaller areas B and C than in A larger area, thereby requiring less time browsing and therefore a shorter period of time lighting.

With links to figv, activation of the integrated circuit 26 controls the LEDs of the LEDs L1, L2, R1 and R2 selectively osveschalo being the Central display area 5, marked as region D. the Central region D can be covered within a predetermined period of time X, for example 10 seconds. Period X lighting is shorter than the period Z lighting for the area A, but is greater than the period Y for areas B and C, because D is smaller than the area A, but is greater than area B, and C.

Activation of the integrated circuit 26 controls the LEDs LEDs U1 and U2 selectively covers essentially the top edge of the display 5, identified as area G. similarly, activation of the integrated circuit 26 controls the LEDs LEDs B1 and B2 selectively covers essentially the bottom edge of the display 5, identified as area H. Area G and H each can be dealt with within a predetermined period V period of time, such as 2-3 seconds. Period V lighting is usually short, because the field G and H are smaller in comparison with, for example, areas B and C, and a small amount of information that can be contained in areas G and H, are likely to require only a short period of time to view.

With links to figs, activation of the integrated circuit 26 controls the LEDs of the LEDs L1 and L2 are selectively covers essentially the left half of the display 5, marked as area E. similarly, activation of the integrated circuit 26 controls the LEDs LEDs R2 and R2 selection is the rule covers essentially the right half of the display 5, identified as area f Area E and F each can be covered within a predetermined time period W, for example 3-4 seconds. The period W of the light is shorter than that for areas A-D, but more than that for areas G and H, because more information can be displayed in the areas E and F than in areas G and H, therefore requiring a longer period of view.

Figs also illustrates the selective illumination of the corner areas of the display 5. Activation of the LEDs U1 and L1 integrated circuit 26 controls the LEDs selectively covers essentially the upper left corner of the display area 5, which is identified as region I and approximately delimited by the dotted line 38. Activation of the integrated circuit 26 controls the LEDs LEDs U2 and R1 selectively covers essentially the upper right corner of the display 5, which is identified as region J and approximately delimited by the dotted line 39. Similarly, activation of the integrated circuit 26 controls the LEDs LEDs L2 and B1 selectively illuminates essentially lower left corner of the display 5, which is identified as region K and approximately delimited by the dotted line 40. Activation of the integrated circuit 26 controls the LEDs LEDs R2 and B2 selectively illuminates essentially lower right corner of the display 5, which is identified to the to region L and approximately delimited by the dotted line 41. Area I, J, K and L each can be covered within a predetermined time period U, for example 2-3 seconds. Period U-time lighting is usually short due to the small amount of information that can be displayed in the regions I, J, K and L.

Method for selective illumination of regions of the display 5 is described below with reference to the sequence of operations shown in figure 5 On the stage 100 figure 5 original portable electronic device type mobile phone 1 shown in figure 1, may be in a state such as a standby state, in which none of the elements 27 lighting is not activated, and therefore, the display 5 is not lit.

On the stage 101 in the absence of events that could cause the update of the display 5 and require lighting display, the display remains unlit condition. However, if the apparatus 1 has detected an event that will trigger the update of the display and activates the lighting of the display, such as an incoming call, a reminder, an incoming text message or pressing a key or the like, is checking to verify whether the way lighting control to reduce the power consumption of a battery according to the present invention, as represented by step 102. If not allowed, all of the elements 27 of the light-activated module 21 lighting control through the integrated circuit 26 is Board LEDs in response to this event, and the entire display 5 is illuminated, as shown by step 103, and the method terminates.

If the lighting control to reduce the power consumption of a battery according to the present invention is allowed, step 104 of the method includes checking whether a display area containing information that you want to view, is one of the areas (B - L) of the display 5, as described above with respect to table 37 display. If not, for example, if the information that you want to view, occupies essentially the entire area of the display 5 (e.g., region A), all elements 27 lighting activate, as shown by step 103, to allow a clear view all the information.

However, if the information that you want to view, occupies the display area 5, the module 20 display control and PI determines at step 105 of the method according to at least one corresponding region (B-L) of the display 5, which require lighting during the upgrade elements 27 lighting, by reference to table 37 display, shown in figure 4. For example, if the information should be displayed and viewed, is essentially the top half of the display 5, the module 20 display control and PI determines with reference to the map table in figure 4, it corresponds to the region B of the display 5 shown in figa. Module 20 control the FL display and PI then enters the location of the display area 5, be the lighting module 21 lighting control.

At step 106 figure 5 based on the location area, adopted from module 20 controls the display and the IP module 21 lighting control defines the elements 27 lighting, which must be activated, and identifies a predefined period of time lighting by reference to table 37 display, shown in figure 4.

With reference to step 107 module 21 lighting control issues a command to an integrated circuit 26 controls the LEDs - what elements 27 lighting need to step up and announce in advance a certain period of time lighting. Integrated circuit 26 controls the LEDs then activates the elements 27 lighting in accordance with commands from module 21 lighting control to selectively illuminate the area or perhaps region) of the display 5, containing the information you want to view.

Below are described with reference to Fig.6 and 7 two specific example of selective illumination of the display area 5 in the apparatus 1 in accordance with the present invention.

With reference to the example shown in Fig.6, the incoming call alert detect transmit-receive antenna 7, which leads to the extraction software application 19 in the form of Annex 34 incoming call from ROM 14 characters and implementation of the microprocessor is m 13. Annex 34 incoming call instructs the module 20 display control and PI to modify the display 5 via a scheme 23 LCD control to display the window 33 of the dialogue in the Central region D of the display 5. The window 33 of the dialogue indicates that there is an incoming call, and specifies the identification information of the caller. Module 20 display control and PI determines the display area 5, which should display information. Module 20 controls the display and the PI informs the module 21 lighting control on the display area 5, which will contain information that you want to view, for example, the window 33 of the dialogue. In this example, the area that you want to view, is essentially a Central area corresponding to the area D.

Based on the location area, adopted from module 20 controls the display and the IP module 21 lighting control defines the elements 27 lighting, which must be activated, and identifies a predefined period of time lighting from table 37 display, shown in figure 4. Pre-determined period of lighting time X during the period D is set to 10 seconds, as indicated in figure 4.

Module 21 lighting control sends one or more signals on the integrated circuit 26 controls the LEDs to activate the corresponding elements 27 light the Oia within a predetermined period of time. In this example, and with reference to the table display in figure 4 the lighting elements that must be activated to selectively illuminate the Central area, are the LEDs L1, L2, R1 and R2. Circuit 26 controls the LEDs then activates the LEDs L1, L2, R1 and R2 via the bus 28 of the control signals and line 28a of the control signals. Fig.6 shows the LEDs L1, L2, R2, and R2 in the active state, so as to cover essentially the Central region D containing the information you want to view. The other LEDs U1, U2, B1 and B2 may not be activated and therefore turned off, such that the top and bottom edges of the display 5, designated as area G and H, respectively, as shown in figv not covered. Alternatively, the remaining LEDs U1, U2, B1 and B2 may be partially controlled by the circuit 26 controls the LEDs so that they are activated, but have a brightness that is less than the brightness of the LEDs L1, L2, R2 and R2. For example, the second brightness of the illumination provided by the LEDs U1, U2, B1 and B2 may be equal to half of the first brightness provided by the LEDs L1, L2, R2 and R2. Preferably, the LEDs U1, U2, B1 and B2 do not activate to reduce the power requirements of the battery.

In relation to the example shown in Fig.7, if an alert/reminder were installed on the portable electronic device in the pre-op is edeleny time of issuing alerts/reminders software application 19 in the form of Annex 35 alerts/reminders should be extracted from the ROM 14 characters for execution by the microprocessor 13.

Annex 35 alerts/reminders instructs the module 20 display control and PI to modify the display 5 via a scheme 23 LCD control to display the icon 36 alerts/reminders at the top of the display 5. Module 20 controls the display and the PI informs the module 21 lighting control on the display area 5, which contains information that you want to view, for example the icon 36 alerts/reminders. In this example, the area that you want to view, is the top edge of the corresponding region G.

Module 21 lighting control then determines the elements 27 lighting, which must be activated to selectively illuminate the region G, and determines a predefined period of time lighting from table 37 display of figure 4. For region G of the pre-determined period of time lighting V is from 2 to 3 seconds.

Module 21 lighting control sends one or more signals on the integrated circuit 26 controls the LEDs to selectively activate the appropriate elements 27 lighting within a predetermined period of time. In this example, and with reference to table 37 display in figure 4 the lighting elements that must be activated to illuminate the top edge, are the LEDs U1 and U2. Circuit 26 controls the LEDs then activeserve the LEDs U1 and U2 via the bus 28 of the control signals and line 28a of the control signals. Fig.7 shows the LEDs U1 and U2 in the active state, so as to illuminate the upper boundary of the region G containing the information you want to view. The rest of the LEDs L1, L2, R1, R2, B1 and B2 may not be activated and therefore turned off, so that the Central region D and the lower edge area H display 5 is not lit. Alternatively, the LEDs L1, L2, R1, R2, B1 and B2 may be partially controlled by the circuit 26 controls the LEDs so that they are activated, but have a second brightness which is lower than the first brightness LEDs U1 and U2. Preferably, the LEDs L1, L2, R2, R2, B1 and B2 do not activate to reduce power consumption in battery.

In accordance with another method of selective lighting control to reduce the power consumption of a battery according to the present invention predefined periods of time lighting can be other than those shown in table 37 show on figure 4, depending on the priority of the event which will trigger the update of the display 5 and activating elements 27 lighting for display lighting.

According to one variant of implementation of each event, which is capable portable electronic device may have a corresponding priority, and the priority of each event can be stored in the table 37 display, according to figure 4. For example, event alerts/reminders may have a higher associated (linked) priority than for example, the event of receiving a text message that may display the received icon (icons) text message. Similarly, the event is an incoming call may have a higher associated priority than such event alerts/reminders. The priority of each event can have an associated pre-determined period of lighting time, so that events with higher priority are highlighted for longer periods than with a lower priority. Alternatively, events can be grouped together and have a priority associated with the event group.

For example, in the scenario described above with reference to Fig.7, in which the icon 36 alerts/reminders displayed in the area G of the display 5, which is covered in 2-3 seconds, it may be desirable to illuminate the icon 36 alerts/reminders for a longer predetermined period of time, to ensure that attention is drawn to the warning/reminder. Therefore, table 37 display can be performed treatment to determine the priority of the event. If the priority is relatively high, but the event takes place in the area for which a lighting period is usually either relatively short, period of time light can be increased with the accordance with the priority of the event. In the scenario shown in Fig.7, the period of lighting time can be increased from 2-3 seconds to, for example, 5-6 seconds, which can be pre-defined period of time lighting associated with the priority events, alerts/reminders. Therefore, although the region G is small compared with, for example, areas B-D, region G is not able to display a lot of information because of the limited area, the predefined period of time lighting for this area may be increased to reflect the priority of the event, which involves displaying information in the display area 5.

In another example, if only a small amount of information, with associated low priority, was displayed in one of the large areas of the display 5, such as areas B, C or D shown in figa and 3B, the period of lighting time can be reduced to reflect the priority of an event and thus reduced consumption of battery energy. For example, if only a small amount of text, such as the time was displayed in the Central region D that does not require pre-determined period of lighting time X equal to 10 seconds to view the information, the time period for lighting could be reduced, for example, up to 3 seconds. In this example, the priority may be associated with a case of pressing, which is proishodit, to view the time.

According to another variant implementation of the present invention, the brightness of the illumination provided by the elements 27 lighting, may depend on the priority associated with each event. The brightness level associated with each priority for each event can be stored in the table 37 display. For example, an event with a higher priority, for example the icon alerts/reminders can be selectively lit to full brightness elements 27 lighting. For comparison, an event with a lower priority, for example, received a text message, may be selectively illuminated with a certain degree full brightness, for example half brightness.

The present invention thus provides a solution to the problem of inefficient lighting displays of portable electronic devices so that, when the information that you want to view, does not occupy the entire display area, the display area containing information that can be selectively illuminated. The present invention therefore overcomes the disadvantages of the prior art, illuminating only the area of the display containing the information you want to view, and do not unnecessarily illuminates the display area, which do not contain information, which leads to reduced consumption of battery energy. Another advantage of using the selected lighting areas of the display, containing information, is that the user's attention is drawn to the information of interest.

In addition, the present invention provides for a period of time of illumination of different areas of the display, which should be adapted to the time required to view the information displayed in the respective fields. The area of larger size may contain information and therefore can be lit for longer periods than smaller areas, which can only show a smaller amount of information. Therefore, the display area is not covered for unnecessary periods of time, leading to reduced consumption of battery energy.

Another advantage of the context-dependent ways of lighting according to the present invention is that the periods of illumination can vary depending on the priority of each event. Events with a higher associated priority can be lit for longer periods of time than with a lower priority, to ensure that information about the event with the higher priority is illuminated for a sufficient period. Therefore, events with a higher priority, which can be displayed and selectively illuminated in smaller areas of the display in accordance with the tvii with one embodiment of the present invention, can be ensured over a long period of coverage than otherwise previously determined for this area. Although a longer pre-determined period of lighting time can be ensured in this embodiment, use less battery power compared to prior art still achieved, because selectively illuminated display area instead of the full display area.

In addition, the present invention provides such a possibility that the brightness of the light depends on the priority associated with each event. Events with a higher priority can be selectively illuminated more brightly than events with a lower priority, thus providing another way reduced the energy consumption of battery in portable electronic devices.

The present invention is particularly suitable for reducing the power consumption of a battery in portable electronic devices, which contain large color displays, which require a variety of lighting elements such as LEDs, for background light (backlight). However, it should be clear that the present invention is not limited to the led background lighting or displays that are LCD screen with backlight. The present invention can use the I with other types of display and with alternative lighting elements. In addition, the present invention is not limited to pre-defined periods of time lighting provided in, for example, table 37 display, according to figure 4, which can be used an alternative pre-defined periods of time lighting. Similarly, the present invention is not limited by the number of elements 27 of the light used for display lighting, or specific areas (B-L), which selectively covers. Provides that can be used an alternative number of lighting elements and alternative fields.

Throughout the description the goal was to disclose the invention without limiting the invention to any one embodiment or specific collection of features. Specialists in the art can implement a variety of specific embodiments, which must, however, fall in the scope of the invention.
