Abstract:
A display control method inputs a plurality of frames into a display, which records a sequential flashing threshold value. Each of the frames has a plurality of pixels. The display control method includes a frames-comparing procedure, a play-mode determining procedure, and a sequential flashing controlling procedure. The frames-comparing procedure generates a motion activity value by way of comparing pixels between two of the frames. The play-mode determining procedure determines whether the two frames are in a relationship of a motion mode or not according to the motion activity value and the flashing threshold value, and therefore generates a sequential flashing controlling signal. The sequential flashing controlling procedure performs a sequential flashing process according to the sequential flashing controlling signal.
