As to the problem in related technology that the energy consumption of the high-resolution display panel is too high, some embodiments of the disclosure provide a method for driving a display panel and a display device. In order to make the objective, the technology solutions and the advantages of the present disclosure more clear, the present disclosure will be further described in detail with reference to the accompanying drawings. Obviously, all embodiments described are just a part but not all of the embodiments disclosed in present disclosure. All other embodiments acquired by those skilled in the art based on the embodiments of the present disclosure without creative efforts fall into the scope of the present disclosure.
The shapes and sizes of the various components in the drawings do not reflect true proportions, and are merely intended to illustrate the present disclosure.
An embodiment of the present disclosure provides a method for driving a display panel, wherein as shown in
S101, a viewing distance between a viewer and the display panel is acquired;
S102, the number of pixels to be lightened in the display panel is determined based on the viewing distance; wherein the larger the viewing distance is, the smaller the number of pixels to be lightened in the display panel is; and
S103, display is performed based on the determined number of pixels to be lightened.
An embodiment of the present disclosure provides a driving method of a display panel, wherein the display panel includes a plurality of pixels arranged in an array, each pixel includes sub-pixels of at least three colors, and the method includes: a viewing distance between a viewer and a display panel is acquired; the number of pixels to be lightened in the display panel is determined based on the viewing distance; wherein the larger the viewing distance is, the smaller the number of pixels to be lightened in the display panel is; and display is performed based on the determined number of pixels to be lightened. That is to say, the positions and numbers of sub-pixels to be lightened in the display panel are determined based on the distance between the viewer and the display panel. The display panel performs high-resolution display when the distance is relatively close and performs low-resolution display when the distance is relatively far, so that the energy consumption of the display panel is lowered.
The viewing distance between the viewer and the display panel can be acquired by using a distance sensor built in the display panel. The distance sensor can be an optical displacement sensor, an ultrasonic displacement sensor, and so on, which is not specifically limited.
Alternatively, in some embodiments, wherein the step that the number of pixels to be lightened in the display panel is determined based on the acquired viewing distance includes:
the number of pixels to be lightened in the display panel is determined based on the viewing distance and the corresponding relationship between preset different distance ranges and the numbers of pixels to be lightened;
wherein, the numbers of pixels to be lightened corresponding to different distance ranges are different, and the larger the distance range is, the smaller the number of the corresponding pixels to be lightened is.
In some embodiments, the different numbers of pixels to be lightened in the display panel represent different resolutions of the display panel during display. The greater the number of pixels to be lightened is, the higher the resolution is during display.
In the present disclosure, in the corresponding relationship between the preset different distance ranges and the numbers of pixels to be lightened, the more the distance ranges are set within a certain range, the more the display resolutions the display panel has, and the viewing result can be guaranteed on the basis of energy saving. In some embodiments, it can be set according to practical experience. For example, 0˜K1 is a distance range, when the number of pixels to be lightened is the number of all pixels in the display panel, corresponding display resolution is the highest. K1˜K2 is a distance range, when the number of pixels to be lightened is the number of most pixels in the display panel, corresponding display resolution is lower. K2˜∞ is a distance range, when the number of pixels to be lightened is the number of a small part of pixels in the display panel, corresponding display resolution is the lowest.
Alternatively, in some embodiments, the step that the number of pixels to be lightened in the display panel is determined based on the viewing distance and the corresponding relationship between the preset different distance ranges and the numbers of pixels to be lightened includes:
the distance range to which the viewing distance belongs is determined; and
the number of pixels to be lightened in the display panel is determined by searching the corresponding relationship between the preset different distance ranges and the numbers of pixels to be lightened based on the determined distance range.
The following will be explained in detail as an example to describe the driving method of the display panel described in the embodiment of the present disclosure: 0˜K1 is taken as a distance range and the number of pixels to be lightened is X1, K1˜K2 is taken as a distance range and the number of pixels to be lightened is X2, and K2˜∞ is taken as a distance range and the number of pixels to be lightened is X3, wherein X1 is the number of all pixels in the display panel, and X1>X2>X3.
As shown in
S201, a viewing distance between a viewer and the display panel is acquired;
S202, whether the viewing distance is smaller than or equal to K1 is determined;
If yes, S203 is executed, and if not, S204 is executed;
S203, the number of pixels to be lightened in the display panel is determined as X1, and display is performed based on the determined number of pixels to be lightened;
S204, whether the viewing distance is smaller than or equal to K2 is determined; If yes, S205 is executed, and if not, S206 is executed; S205, the number of pixels to be lightened in the display panel is determined as X2, and display is performed based on the determined number of pixels to be lightened;
S206, the number of pixels to be lightened in the display panel is determined as X3, and display is performed based on the determined number of pixels to be lightened.
When the view distance is large, the viewer's resolution requirements for the display panel are not so high as when the viewer watches the display panel at a close range, Therefore, the driving method provided by the embodiment of the present disclosure changes the resolution of the display panel according to the viewing distance, and the larger the viewing distance is, the lower the display resolution of the display panel is, i.e. by reducing the resolution when viewing from a long distance, the energy consumption of the display panel can be reduced without affecting the visual effect of the viewer.
Alternatively, in some embodiments, the step that display is performed based on the determined number of pixels to be lightened includes:
positions of pixels to be lightened are determined based on the determined number of pixels to be lightened; and
display is performed based on the positions of pixels to be lightened and a data signal corresponding to the pixels to be lightened.
In some embodiments, when the display resolution is reduced, the display effect is directly affected by the positions of pixels to be lightened. In order to ensure the display effect, the positions of pixels to be lightened will be described in the present disclosure below in embodiments.
Alternatively, in some embodiments, the step that positions of pixels to be lightened are determined based on the determined number of pixels to be lightened includes:
when the number of pixels to be lightened is M/N of the total number of the pixels in the display panel, as shown in
Further, in some embodiments, in each pixel unit, the more uniformly the M pixels to be lightened are arranged, the better the display effect will be.
