Embodiment
Fig. 1 is the process flow diagram of screen display electricity saving method according to a first embodiment of the present invention.As shown in Figure 1, in step sl, be at least two viewing areas by screen divider, the brightness of each viewing area is controlled respectively by display control module.Those skilled in the art know, as required, screen divider can be become multiple viewing area, such as three, four, five, even more, and can be controlled its brightness by different display control modules each viewing area.Those skilled in the art also know, also can adopt a display control module, control respectively to each viewing area.Those skilled in the art also know, conventional described display control module can comprise and is arranged on both sides, viewing area, center or any applicable position, to illuminate one group or a LED of viewing area, and drives LED drive circuit or the LED drive chip of this LED.In the present invention, each viewing area is illuminated by a group or a LED, and this group or this LED have a LED drive circuit or LED drive chip to control.Those skilled in the art also know, these at least two viewing areas can be horizontally disposed with, and also can vertically arrange.In other embodiments of the invention, these at least two viewing areas can also otherwise be arranged, such as, arrange etc. with one heart, and the present invention is not by the restriction of the set-up mode of viewing area.
In step s 2, receive user's trigger pip from described screen, generate the first brightness control signal and the second brightness control signal based on the position coordinates scope of described at least two viewing areas and the position coordinates scope of described user's trigger pip.Those skilled in the art know, the sliding action that this user's trigger pip can touch based on user, the trigger action of contact screen, user streak screen.The position coordinates scope of described user's trigger pip can comprise multiple position coordinates, also can comprise a position coordinates.The position coordinates scope of the described position coordinates scope based on described at least two viewing areas and described user's trigger pip generate the first brightness control signal and the second brightness control signal position coordinates scope that can comprise based on described user's trigger pip whether fall into described at least two viewing areas position coordinates scope or whether overlap with the position coordinates scope of described at least two viewing areas and generate the first brightness control signal and the second brightness control signal.Those skilled in the art know, can be judged by the position coordinates scope of the position coordinates scope of more described user's trigger pip and described at least two viewing areas.Those skilled in the art know, the brightness that described first brightness control signal controls is different from the brightness that described second brightness control signal controls.Those skilled in the art know, the brightness of that or those viewing area that this first brightness control signal can control that the position coordinates scope of described user's trigger pip falls into, described second brightness control signal can control the brightness of all the other viewing areas.
In step s3, described display control module control respectively based on described first brightness control signal and described second brightness control signal described in the brightness of at least two viewing areas.Those skilled in the art know, in the present invention, described display control module, after receiving the first brightness control signal, is sent to corresponding LED drive circuit.This LED drive circuit drives its corresponding a group or a LED, thus controls the brightness of the viewing area at its place.In one embodiment of the invention, the brightness of control LED can uprise, thus improve the brightness of this viewing area.Described display control module, after receiving the second brightness control signal, is sent to corresponding LED drive circuit.This LED drive circuit drives its corresponding a group or a LED, thus controls the brightness of the viewing area at its place.In one embodiment of the invention, can the brightness step-down of control LED, thus reduce the brightness of this viewing area.In other embodiments of the invention, also oppositely can arrange, such as, make the brightness step-down of the viewing area that the first brightness control signal is corresponding, and the brightness of viewing area corresponding to the second brightness control signal is uprised.Otherwise also can.
Those skilled in the art know, before user's triggering starts, can be that the brightness of whole screen is high situation, or the brightness of whole screen be low situation, also can be the brightness of part viewing area for high, and the brightness of another part viewing area is low state.Those skilled in the art know, in further embodiment of the present invention, the brightness of described LED is adjustable.Such as when needing the brightness reducing a certain viewing area, the brightness of the LED that LED drive circuit is corresponding can be made to reduce, but not extinguish, or the brightness of LED is raised but not is upgraded to the highest.Or, be only the part LED opening or close in one group of LED.Based on instruction of the present invention, those skilled in the art know, only the first brightness control signal need be made to be different from the second brightness control signal.But those skilled in the art know further, preferably the brightness that the first brightness control signal controls is set to the highest, and the brightness that the second brightness control signal controls is set to minimum, namely close LED.
In another embodiment of the invention, this screen can be LED display, the display screen be namely made up of multiple LED.Now described display control module only can comprise driving circuit, is controlled the brightness of each LED by driving circuit, thus controls the brightness of screen regional.
Implement screen display electricity saving method of the present invention, by the brightness of the optionally viewing area of display screen, reduce power consumption, enhancing battery is as the battery durable ability of power-supply device, and adding users is experienced.Further, user can select various gesture to be that brightness is selected in viewing area, thus further enhancing the experience of user.
Fig. 2 is the process flow diagram of screen display electricity saving method according to a second embodiment of the present invention.As shown in Figure 2,
In step sl, be at least two viewing areas by screen divider, the brightness of each viewing area is controlled respectively by display control module.Those skilled in the art know, as required, screen divider can be become multiple viewing area, such as three, four, five, even more, and can be controlled its brightness by different display control modules each viewing area.Those skilled in the art also know, also can adopt a display control module, control respectively to each viewing area.Those skilled in the art also know, conventional described display control module can comprise and is arranged on both sides, viewing area, center or any applicable position, to illuminate one group or a LED of viewing area, and drives LED drive circuit or the LED drive chip of this LED.In the present invention, each viewing area is illuminated by a group or a LED, and this group or this LED have a LED drive circuit or LED drive chip to control.Those skilled in the art also know, these at least two viewing areas can be horizontally disposed with, and also can vertically arrange.In other embodiments of the invention, these at least two viewing areas can also otherwise be arranged, such as, arrange etc. with one heart, and the present invention is not by the restriction of the set-up mode of viewing area.
