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 skin color detection to the image pixels of the image to display to determine nude pixel and non skin color pixel; setting different skin color weights for the nude pixel and the non skin color pixel; implementing the color washout compensation to the image to display according to the skin color weight; driving the liquid crystal panel to show the image to display after the color washout compensation. With the aforesaid arrangement, the present invention preferably improves the resolution and viewing angle of the display at the same time.
