Abstract: A method for reducing a color edge phenomenon of a display panel is provided. The method is applicable to a display panel including a plurality of pixel units. The method includes: performing pixel adjustment on the pixel units at edges of the display panel. Each pixel unit includes at least three sub-pixels: a first sub-pixel, a second sub-pixel, and a third sub-pixel. By adjusting positions, areas, or brightness of the sub-pixels, the color edge phenomenon of the display panel is effectively reduced or avoided.

Abstract: A drive circuit for driving a display panel includes a dynamic refresh unit, a timer, and a black insertion drive unit. The dynamic refresh unit is configured to output a dynamic refresh signal, so as to control the display panel to display a plurality of frames in sequence. A frame time of each of the frames is adjusted according to the dynamic refresh signal. The timer is configured to compute a black insertion time signal. The black insertion drive unit is configured to output a black insertion drive signal according to the black insertion time signal, so as to perform black insertion on the frames.
