Abstract:
An apparatus of driving a liquid crystal display includes a signal controller. The signal controller has a frame memory and an image type detector. The signal controller compares image data for a present frame from an external device with image data for a previous frame stored in the frame memory and determines whether the image data represent still image. If the image data represent a sill image, the signal controller suspends a predetermined control operation and also suspends supply voltages to elements required for the predetermined control operation.
