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 color detection to the image pixels of the image to display to determine a predetermined color pixel; implementing adjustment to the original gray scale values of the respective primary color components of the predetermined color pixel to make that a difference between a relatively higher original gray scale value and a relatively lower original gray scale value before adjustment becomes larger after adjustment for the same predetermined color pixel; implementing color washout compensation to the image to display; 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.
