Abstract
The present invention provides a drive method and a drive device of a liquid crystal display, and the drive method comprises: receiving an image to display; implementing high frequency detection to the image pixels of the image to display to determine color differences of the respective image pixels and the adjacent image pixels; implementing the color washout compensation to the image to display according to the high frequency weight; driving the liquid crystal panel to show the image to display after the color washout compensation. With the aforesaid arrangement, the present invention can reduce the color washout under large view angle to promote the display effect of the large view angle.
