    摘要: The present application provides a method for driving a display panel, including: providing data signals to M rows of sub-pixels, wherein providing data signals to an X-th row of sub-pixels includes: determining, for each sub-pixel in the X-th row, a grayscale compensation value for a data signal provided to the sub-pixel; determining, for each sub-pixel, an actual grayscale corresponding to the sub-pixel according to the grayscale compensation value and a theoretical grayscale value Lx of the sub-pixel; and providing the data signals to the X-th row of sub-pixels according to the actual grayscales corresponding to the respective sub-pixels in the X-th row. The grayscale compensation value is determined by: calculating a grayscale difference δ by a formula δ=Lx−Lx-1, where grayscale Lx-1 is a theoretical grayscale of an adjacent sub-pixel in an (X−1)-th row; and determining the grayscale compensation value according to the grayscale difference and a grayscale compensation look-up table.

    摘要: The present disclosure provides a pixel structure, a method of driving the same and a display device. The pixel structure includes gate lines, data lines, and a plurality of subpixels arranged in an array form. Subpixels in each row correspond to two gate lines. Each data line corresponds to the subpixels in two adjacent columns, and each data line is arranged between the two adjacent columns of subpixels. Among the subpixels in each row, three adjacent subpixels are in different colors and forms a complete pixel unit. Among the subpixels in each column, three adjacent subpixels are in different colors and forms the complete pixel unit. Among the subpixels in two adjacent columns, the subpixels in two adjacent rows form two complete pixel units each including three subpixels, and two of the three subpixels are shared by the two pixel unit.
