Abstract: The present invention provides a method of display control for a display driver circuit operated in a video mode. The method includes steps of: driving a display panel to display a plurality of image frames having a plurality of active frames and a plurality of blanking frames, and determining whether to transmit a notification to an application processor to indicate whether the application processor needs to output image data according to whether an incoming image frame among the plurality of image frames is one of the plurality of active frames or one of the plurality of blanking frames. Wherein, the display panel is refreshed in each of the plurality of active frames, and not refreshed in each of the plurality of blanking frames.
