LIQUID CRYSTAL PANEL AND DRIVING METHOD THEREOF AND LIQUID CRYSTAL DISPLAY

摘要

The present invention discloses a liquid crystal panel. The panel includes a display area that includes an array of pixel units formed thereon, a source controller, a gamma voltage control section, a gate controller, a chamfer voltage control section, and an image inspection section. The image inspection section classifies images into n classes according to ranking of grey level. The chamfer voltage control section is operated in response to the class of an image to control one of the n chamfer voltage circuits to supply the chamfer voltage to the gate controller and the gamma voltage control section is operated in responses to the class of the image to control one of the n gamma voltage circuits to supply the gamma voltage to the source controller, where n is an integer greater than 1. The present invention also discloses a driving method for the liquid crystal panel and a liquid crystal display including the liquid crystal panel. The liquid crystal panel provided by the present invention allows for reduction of a feed-through voltage ΔV and at the same time reducing the difference of ΔV between high and low grey levels so as to enhance the displaying quality of the liquid crystal panel.
