Fig. 5 is a signaling flow diagram of a second embodiment of a lighting control method according to the present invention. The present embodiment describes a possible implementation manner of the driving chip controlling the light emission of the display panel in the above embodiments. The light emission control method provided in this embodiment can also be applied to the display device shown in fig. 1, and as shown in fig. 5, the light emission control method provided in this embodiment specifically includes:
s501, the application processor AP receives a display mode switching instruction triggered by a user, and the display mode switching instruction is used for indicating the display mode of the display device to be switched from the current display mode to the high-contrast mode.
S502, the application processor AP sends image data corresponding to the high-contrast mode to the driving chip, wherein the image data comprises gray scale information of each pixel on the image to be displayed and a gamma section identification corresponding to each pixel on the image to be displayed.
The implementation manners of S501-S502 can be referred to as S201-S202 above. The present invention will not be described herein.
S503, the driving chip determines the gamma section corresponding to each pixel on the image to be displayed according to the gamma section identification corresponding to each pixel on the image to be displayed.
S504, the driving chip corrects the gray scale information corresponding to each pixel by using the gamma section corresponding to each pixel on the image to be displayed, and the gray scale correction value corresponding to each pixel on the image to be displayed is obtained.
And S505, the driving chip controls the display panel to emit light according to the gray scale correction value corresponding to each pixel on the image to be displayed.
The driving chip receives gray scale information of each pixel on the image to be displayed and a gamma section identifier corresponding to each pixel on the image to be displayed, which are sent by the application processor AP, and then determines a gamma section corresponding to each pixel on the image to be displayed according to the gamma section identifier corresponding to each pixel on the image to be displayed.
The following examples illustrate:
referring to fig. 6, the image to be displayed includes 12 pixels, which are pixel 11, pixel 12, pixel 13, pixel 21, pixel 22, pixel 23, pixel 31, pixel 32, pixel 33, pixel 41, pixel 42, and pixel 43. The image data sent by the application processor AP to the driver chip includes gray scale information of each of the 12 pixels and a gamma segment identifier corresponding to each pixel. Referring to fig. 6, the gray scale information of the pixel 11 is 255, the corresponding gamma segment identifier is 1, and the gray scale information and the gamma segment identifier of other pixels are not listed in fig. 6. Suppose that three gamma segments are stored in the driving chip, which are respectively a high-brightness gamma segment, a medium-brightness gamma segment and a low-brightness gamma segment, wherein the identifier corresponding to the high-brightness gamma segment is identifier 1, the identifier corresponding to the medium-brightness gamma segment is identifier 2, and the identifier corresponding to the low-brightness gamma segment is identifier 3. Referring to fig. 7, after the driving chip receives the gray scale information of each of the 12 pixels and the gamma segment identifier corresponding to each pixel, it may be determined that the gamma segments corresponding to the pixel 11, the pixel 12, and the pixel 13 are all high brightness gamma segments, and the gamma segments corresponding to the pixel 21, the pixel 22, the pixel 23, the pixel 31, the pixel 32, the pixel 33, the pixel 41, the pixel 42, and the pixel 43 are all low brightness gamma segments. The driving chip may gamma-correct the pixels 11, 12, and 13 using the high brightness gamma segments, and gamma-correct the pixels 21, 22, 23, 31, 32, 33, 41, 42, and 43 using the low brightness gamma segments, respectively. Because the drive chip corrects the pixels with higher gray scales by using the high-brightness gamma segments and corrects the pixels with lower gray scales by using the low-brightness gamma segments, the display brightness of the pixels with higher gray scales on the image can be increased, and the display brightness of the pixels with lower gray scales is reduced, so that the image hierarchy is clearer, and the watching experience of a user is improved.
The principle that the driving chip performs gamma correction on the gray scale information by using the gamma segment and the principle that the display panel is controlled to emit light according to the corrected gray scale information after the corrected gray scale information is obtained can be referred to in the prior art, and the present invention is not described herein again.
In the light emission control method provided by this embodiment, after receiving the gray scale information of each pixel on the image to be displayed and the gamma segment identifier corresponding to each pixel on the image to be displayed, the driving chip determines the gamma segment corresponding to each pixel on the image to be displayed according to the gamma segment identifier corresponding to each pixel on the image to be displayed, corrects the gray scale information corresponding to each pixel on the image to be displayed to obtain the gray scale correction value corresponding to each pixel on the image to be displayed, and controls the display panel to emit light according to the gray scale correction value corresponding to each pixel on the image to be displayed, because the driving chip performs different degrees of gamma correction on the gray scale information of each pixel according to the gray scale information of each pixel, the luminance of the pixel with a high gray scale can be increased, and the luminance of the pixel with a low gray scale can be decreased, therefore, the display image is more distinct in level, the local contrast is more prominent, and the watching experience of a user is improved.
