    Abstract: 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.
