Abstract: A method for driving display of a display panel, a display driver chip and a display device are provided. The method includes: acquiring a to-be-displayed grayscale of a sub-pixel in a frame of a to-be-displayed image; determining whether the to-be-displayed grayscale meets a grayscale optimization condition of a gamma curve; on determining that the to-be-displayed grayscale meets the grayscale optimization condition of the gamma curve, dividing a refresh period of the to-be-displayed image into sub-frames; and in the refresh period of the to-be-displayed image, controlling the sub-pixel to display first grayscales based on first data signals; and the first grayscales are not equal to the to-be-displayed grayscale, the first grayscales and the first data signals corresponding to the first grayscales satisfy the gamma curve.

Abstract: A method and a device for driving a display panel, and a display device are provided. The method including dividing a frame into N sub-frames, the N sub-frames corresponding to N sets of first gamma curves respectively, and the N sub-frames including at least two consecutive first sub-frames; obtaining a display grayscale of a sub-pixel in each first sub-frame based on an original grayscale of a sub-pixel in a frame image to be displayed, a set of second gamma curves, and one set of first gamma curves corresponding to the first sub-frame; and driving the display panel to display sub-frame images sequentially during the N sub-frames. A display voltage of the sub-pixel when the display panel displays one sub-frame image during one first sub-frames is obtained based on the set of second gamma curves and the display grayscale of the sub-pixel in the first sub-frame.
