The following description will take the original picture as a pure color picture (the gray scale values are all 128) as an example:
Under the condition that the gray-scale values of the original gray-scale data of each pixel to be input to the display panel in the original picture are equal (the gray-scale values are 128), the gray-scale value of the gray-scale data of the pixel to be input to the display panel in the second picture in the 2i-1 th pixel column and the 2j-1 th pixel row is larger than the gray-scale value of the gray-scale data of the pixel to be input to the display panel in the third picture in the 2i-1 th pixel column and the 2 j-th pixel row, the gray-scale value of the gray-scale data of the pixel to be input to the display panel in the second picture in the 2i-1 th pixel column and the 2j-1 th pixel row is larger than the gray-scale value of the gray-scale data of the pixel to be input to the display panel in the 2i-1 th pixel column and the 2 j-th pixel row, the gray-scale data of the pixel to be input to the display panel in the second picture in the 2i-1 th pixel column and the 2 j-th pixel row is larger than the gray-scale data of the pixel to be input to the display panel in the 2i-1 th pixel column is larger than the gray-scale data of the pixel to be input to the display panel in the 2i-1 th pixel column is equal to the gray-pixel column.
In the display device and the driving method thereof provided by the present application, since one frame of the original picture is generated into one frame of the first picture according to a View Angle Compensation (VAC) technique, and generating a frame of second picture and a frame of third picture according to the first picture after the visual angle compensation, wherein the second gray scale data of the second picture comprises gray scale data of pixels of an odd pixel row to be input to the display panel in the first picture, the third gray-scale data of the third picture includes gray-scale data of pixels of an even pixel row to be input to the display panel in the first picture, and turning on the pixels of the odd pixel rows row by row in a first driving period in which the display panel displays a second picture, turning on the pixels of the even pixel rows row by row in a second driving period in which the display panel displays a third picture, therefore, the display device provided by the application can make the change degree of the gray scale value of the gray scale data displayed by the second picture of each frame smaller on the premise of realizing the compensation of the visual angle (the starting of the VAC function), and the gray-scale value of the gray-scale data displayed on the third picture of each frame is also changed to a smaller extent, that is, in the driving period (first driving period, second driving period) of one frame of picture, the inversion of the gray-scale data transmitted by one data line is small, so that the gray scale value of the gray scale data input to the odd pixel row and the even pixel row is prevented from frequently and greatly changing (the gray scale data is turned over greatly) when the display panel displays a frame of picture, and thus the load of the display device and the power consumption in a state where the VAC function is turned on can be reduced.
The above description of the display device and the driving method thereof provided in the embodiments of the present application is merely for aiding in understanding the core concept of the present application, and the above description should not be construed as limiting the scope of the present application.
