Patent ID: 7400311

Claim:
A response time accelerator for driving a liquid crystal display (LCD) comprising: a frame memory unit that updates and stores one or more frames of previous data; a table memory unit that stores predetermined mapped panel output values, predetermined mapped panel characteristic values, and flag information corresponding to the predetermined mapped panel characteristic values; and an acceleration unit that reads the previous data corresponding to input current data, reads and decodes the predetermined mapped panel output value, predetermined mapped panel characteristic value, and flag information corresponding to the previous data and current data, performs interpolations on the decoded mapped panel output value and mapped panel characteristic value according to the flag information, and generates liquid crystal panel data to be output to a liquid crystal panel and previous data of a next frame to be output to the frame memory unit, wherein the acceleration unit determines a gray level at which to generate the liquid crystal panel data based on the flag information set in a previous frame, and wherein the flag information for a next frame is set based on a comparison of the current data and the previous data of a next frame.
