Publisher's Synopsis
A display device (2) includes a processor (13) that outputs drawing data and a timing controller (11) that outputs the drawing data input from the processor according to horizontal synchronization and vertical synchronization. When a still image region where drawing data has not been updated compared with a previous frame and a moving image region where drawing data has been updated compared with a previous frame are included in one frame, the processor transmits data update information, which is for specifying the position of the moving image region or a line including the moving image region, to the timing controller temporally earlier than drawing data of the line including the moving image region. The timing controller performs processing for lowering the frame rate of the still image region or processing for thinning out some of image lines of the still image region based on the data update information.
