Abstract: A driving method of a display panel, a display panel, and a display device are provided. Pixel units are grouped, so that the pixel units include the same number of sub-pixels. Each of the pixel units performs a display grayscale switching in a corresponding switching frame. A number of the sub-pixels having a first display gray level and a number of the sub-pixels having a second display gray level in each of the pixel units are the same. A the frame time of maintaining the first display grayscale by each of the pixel units and a frame time of maintaining the second display grayscale by each of the pixel units are the same.

Abstract: A display panel and a driving method thereof are provided. The display panel includes a plurality of subpixels and a plurality of data lines. The plurality of subpixels are divided into a plurality of unit regions. Two sides of any column of the subpixels correspond to two of the data lines with different polarities respectively. The polarities of the subpixels of any column are same. The unit regions include a plurality of unit subregions. Grayscales of the subpixels in each unit subregion are same, and grayscales of the subpixels in two adjacent unit subregions are different.

Abstract: A display panel includes a plurality of pixel units arranged in an array and a plurality of data lines. The pixel units in two adjacent rows in two adjacent columns form a grayscale combined pixel. The grayscale combined pixel comprises three sub-pixels corresponding to the high grayscale and nine sub-pixels corresponding to the low grayscale.

Abstract: A pixel arrangement structure, a display panel, and a grayscale control method are related. In each pixel group of the pixel arrangement structure, a number of first type pixels is equal to a number of second type pixels. A number of high grayscale sub-pixels, a number of first low grayscale sub-pixels, a number of second low grayscale sub-pixels, and a number of third low grayscale sub-pixels are all equal. For each pixel group, a ratio of the high grayscale sub-pixels to the low grayscale sub-pixels is one to three to improve a display color shift.

Abstract: The present application discloses an image processing method, an image processing device, and a computer device. The image processing method includes: acquiring a first to-be-processed chromaticity data set and a second to-be-processed chromaticity data set of a preset color of a to-be-processed picture, acquiring a Gaussian probability of the preset color, identifying a picture region in the to-be-processed picture that contains the preset color of the preset scene, and acquiring a color output correction value. The method of the present application can effectively improve a color cast phenomenon and a quality of the displayed picture.

Abstract: The application provides a display panel and a driving method thereof. The display panel comprises a plurality of sub-pixels arranged in a matrix, and the sub-pixels are grouped into a plurality of cell areas arranged repeatedly along the row direction and the column direction. Each cell area comprises at least two sub-pixels, with polarities of adjacent sub-pixels opposite to each other. For at least two consecutive frames during a display cycle, the gray-levels of sub-pixels in the cell area maintain unchanged while polarities of the sub-pixels are reversed.
