Abstract
A driving method, a driving device and a liquid crystal display device are provided. The driving device of the LCD display device outputs the target grey value of the nth frame according to the original grey value of the nth frame, the original grey value of the (n−1)th frame and the look-up table. This improves the luminance of the sub-pixel of the nth frame, shortens the required charging time of the sub-pixel when the (n+1)th frame is being displayed. Thus, the sub-pixel of the (n+1)th frame could be efficiently charged and the luminance of the sub-pixel could be increased. In addition, since the luminance increase of the (n+1)th frame is more than that of the nth frame, the contrast of the LCD display could be improved.
