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 block detection to the image pixels of the image to display to determine dimensions of color blocks where the image pixels are; respectively setting block weights for the respective image pixels according to the dimensions of the color blocks; implementing the color washout compensation to the image to display according to the block 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.
