Abstract
An apparatus and method for driving a liquid crystal display to improve the quality of moving pictures are provided. The apparatus includes a transition check unit that determines whether an input image signal between a first frame and a second frame has changed and whether an input image signal between the second frame and a third frame has changed; an overdrive control unit that overdrives the input image signal in the second frame in an overdrive direction if the transition check unit determines that the input image signal between the first and second frames has changed, wherein the overdrive direction is one of an upper direction and lower direction; and an overdrive compensation unit that changes the input image signal in the third frame in an opposite direction to the overdrive direction if the transition check unit determines that the input image signal between the second and third frames has not changed.
