Patent ID: 7483007

Claim:
A method for driving a liquid crystal display that includes a display panel having a common electrode, a plurality of pixel electrodes and an optically compensated birefringence (OCB) liquid crystal layer, the OCB liquid crystal layer positioned between the common electrode and the plurality of pixel electrodes, the driving method comprising: after a liquid crystal display is powered on, turning off a backlight module for a specific period of time; forming a constant DC transition electric field between the common electrode and the plurality of pixel electrodes, and maintaining the constant DC transition electric field continuously for the entire period of time that the backlight module is turned off to cause the liquid crystal to change from a splay state to a bend state, in which forming a constant DC transition electric field comprises applying a common constant DC voltage to the common electrode, and applying a transition constant DC voltage to the plurality of pixel electrodes respectively, the common constant DC voltage being the inverse voltage of the transition constant DC voltage; turning on the backlight module after the specific period of time; and sending an image signal to the display panel after the specific time, and displaying an image on the liquid crystal display in response to the image signal.
