Patent ID: 8537087

Claim:
A method of driving a liquid crystal display, comprising: modulating source data into modulated source data, to be displayed on a display panel, on a look-up table without consideration of a previous frame data by not using a frame memory or a line memory, wherein the look-up table stores the modulated source data corresponding to each gray scale value of all bits or most significant bits of the source data, and wherein the modulated source data, corresponding the respective source data except the lowest and highest gray scale value of the source data, is determined to have a gray scale value higher than a gray scale value of the corresponding source data for high-speed driving; supplying the modulated source data to the display panel during a first period within a frame interval; delaying the source data during the first period and supplying the delayed source data to the display panel during a second period, after the first period, within the frame interval; and applying a black voltage data to the display panel during a third period, after the second period, within the frame interval, the black voltage data corresponding to a black picture to be displayed on the display panel.
