ABSTRACT:
A method of driving a liquid crystal display device includes compressing a current frame data, storing the compressed current frame data in a frame memory, outputting a compressed data of a previous frame from the frame memory, restoring the compressed data of the previous frame, and comparing the restored data of the previous frame with the current frame data, and modulating the current frame data into a predetermined modulated data based on the comparison result.
