Abstract:
1. A liquid crystal display device for compensating a pixel data in accordance with areas of a liquid crystal display panel and sub-frames comprising: a liquid crystal panel having a plurality of gate lines, a plurality of data lines, a plurality of color pixels, each of the color pixels including two sub-pixels which represent two different colors; a timing controller controlling a gate driver and a data driver, and receiving a sub-pixel data stream of two sub-frame format that includes a first sub-pixel data for a first sub-frame and a second sub-pixel data for a second sub-frame, the first sub-pixel data and the second sub-pixel data having different gamma characteristics; the data driver driving the plurality of data lines of the liquid crystal panel; and a time base adaptive overshoot-compensation unit that overshoot-drive-compensates the sub-pixel data of the first sub-frame and the sub-pixel data of the second sub-frame received from the timing controller, with the compensation rate having a difference corresponding to that between the gamma characteristics of the sub-frames, the time base adaptive overshoot-compensation unit including: wherein the selection unit selects one of the first compensation sub-pixel data from the first look up table and the second compensation sub-pixel data from the second look up table in response to the logic condition of the data selection signal and supplies the selected compensation sub-pixel data to the data driver.
