ABSTRACT:
A display device, where the power consumption of a display panel can be reduced by controlling a display time rate, including an average gray scale calculator obtaining an average gray scale by averaging a gray scale of each pixel over an entire screen of one frame and for outputting an average gray scale signal, a display time rate table outputting a magnification signal for reducing the display time rate when the average gray scale exceeds a certain value in accordance with the average gray scale signal, and a timing signal generator generating an erase start signal for erasing the digital video signal written to the each pixel in accordance with the magnification signal.
