Abstract
This invention relates to a residual image improving system for a LCD, thereby effectively improving the residual image effect. The improving system includes: a power supply for providing an operating power; a voltage detector for detecting the voltage level of an external power by comparison to a predetermined voltage level under the operating power and producing a control signal by comparing the result; and a video and timing control unit for outputting a predetermined pattern to the LCD according to the control signal so as to improve the residual image effect.
