Abstract
A memory is provided for storing one field of video signals supplied to a liquid crystal display panel serving as a display portion. Whether the video signals to be displayed have a stationary image portion or a moving image portion is determined by a comparator by comparing the video signals of the last field read out from the memory and the video signals of the present field supplied to the liquid crystal display panel. When it is determined that the video signals have a stationary image portion, the speed of scanning by a driver is reduced. When the scanning speed is low, the power required for the scanning is reduced.
