Abstract:
1. A liquid crystal display device comprising: a timing controller generating control signals for an image display; a gray scale modulator modulating R, G, and B data from the timing controller; a backlight dimming controller generating a back dimming signal that is inversely proportional to the modulated R, G, and B data generated in the gray scale modulator; and an over driving controller selectively overshoot-compensating the modulated R, G, and B data of a current frame based on a comparison of the modulated R, G, and B data of the current frame and the modulated R, G, and B data of a previous frame, wherein a range of gray scale levels of the modulated R, G, and B data is greater than that of the R, G, and B data received from the timing controller, but smaller than that of the overshoot-compensated R, G, and B data.
