Abstract
In the method, first, planning memory makes pixels correspond to addresses in planned memory. Control signal detects whether original pattern in frame is updated. The said original pattern is stored in memory, which contains part of pixels corresponding to part of addresses. Then, when having detected that the original pattern is updated by a new pattern, control signal compares original pattern with new pattern, and new pattern replaces original pattern stored in memory corresponding to part of addresses. Finally, new pattern is outputted to display. Since only changed part in original pattern is updated, dissipation of electric power is reduced. More power is saved because of simplified operation circuit of electronic device.
Description
Technical field
The present invention relates to a kind of display of Digital Data Processing Equipment field of electricity, particularly relate to a kind of difference that before the update displayed picture, will compare new and old picture, and only the part that changes is upgraded, can avoid repeating upgrading that pattern causes power consumption and the How It Works that can save the local repressentation mode display of electric energy.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, its concrete How It Works of How It Works, step, feature and the effect thereof of the local repressentation mode display that foundation the present invention is proposed, describe in detail as after.
Seeing also shown in Figure 1ly, is the circuit block diagram of existing known liquid crystal display-driving module.This liquid crystal display device module 100 comprises LCD 102 and ASIC(Application Specific Integrated Circuit) 104; Wherein, ASIC(Application Specific Integrated Circuit) 104 comprises that static random access memory 106, data controller 108, time schedule controller 110, numeral are to analog controller (analogy controller) 112 and Serial Control circuit 114.In addition, LCD 102 is to be coupled to ASIC(Application Specific Integrated Circuit) 104.
The How It Works of the local repressentation mode display that proposes according to the present invention, this liquid crystal display device module 100 is under normal operation, and picture data can input to time schedule controller 110 with digital signal.Afterwards, time schedule controller 110 can input to data controller 108 with picture data.Then, data controller 108 can input to picture data numeral to analog controller 112.Afterwards, analog controller 112 can will input to LCD 102 to picture data, so demonstrate a picture.
After local mode activated, the operation that must read and write static random access memory 106 was because this is partly close with aforementioned existing known local mode, so no longer repeat.Different is that data controller 108 is stored into the address of picture data according to planning in advance in the static random access memory 106.That is the picture element in the pattern in the picture data all has a corresponding address in static random access memory 106.Under local mode, behind the data input time schedule controller 110 of a display frame, whether Serial Control circuit 114 can upgrade with an original pattern in a controlling signal (Serial Control signal) the detecting display frame.That is ASIC(Application Specific Integrated Circuit) 104 can be done comparison partly with the original picture data that is stored in static random access memory 106 with the new picture data of input timing controller 110.When this controlling signal detects original pattern when being updated to a new pattern, can compare original pattern and new pattern, if the pattern content has some change, then the data controller 108 original pattern data that can will be stored in the static random access memory 106 replace with new pattern data.Moreover if all pictures all need upgrade, then Serial Control circuit 114 transmits one group of controlling signal (Serial Control signal) to time schedule controller 110.Afterwards, time schedule controller 110 is with Serial Control signal input data recording controller 108.Then, data controller 108 writes static random access memory 106 to all picture datas.On the other hand, pattern needs to upgrade if only have partly, and then 108 corresponding pattern data of data controller write the corresponding address of static random access memory 106, and all the other partly will not upgrade.
Seeing also shown in Figure 2ly, is the panel of LCD figure of a preferred embodiment of the present invention.Suppose that date pattern 204 is arranged on the above-mentioned LCD 102, the strong and weak pattern 206 of signal and the strong and weak pattern 208 of battery.Please be shown in Figure 3 in conjunction with consulting simultaneously, be the memory mapping synoptic diagram of a preferred embodiment of the present invention.The picture element data storage of supposing date pattern 204 is 302 (X1Y1) in the address, and the picture element data storage of the strong and weak pattern 206 of signal is 304 (X1Y2) in the address, and the picture element data storage of the strong and weak pattern 208 of battery in the address 306 (XnYn).Wherein, address 302,304 and 306 is the address of planning in advance.Under local mode, when one comprise the display frame data input time schedule controller 110 of the strong and weak pattern 206 of date pattern 204, signal and the strong and weak pattern 208 of battery after, whether Serial Control circuit 114 can be detected these three patterns with a controlling signal and upgrade.That is ASIC(Application Specific Integrated Circuit) 104 can will compare corresponding to the data in the address 302,304 and 306 that is stored in the static random access memory 106 in the new picture of input timing controller 110.Afterwards, if only there is the pattern of the strong and weak pattern 206 of signal to change in these three patterns, then data controller 108 only upgrades the data in the address 304, and does not upgrade the remaining address data.At last, time schedule controller 110 is shown in data in the static random access memory 106 on the LCD 102.
The How It Works of local repressentation mode display of the present invention is applicable to the display that is in local mode.Because the difference of the new and old picture of comparison before the update displayed picture, and only the part that changes is upgraded, the power consumption that causes so can avoid repeating to upgrade pattern, and can save electric energy.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the method that can utilize above-mentioned announcement and technology contents are made a little change or be modified to the equivalent embodiment of equivalent variations, but every content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
