Abstract:
1. A method for driving a liquid crystal display (LCD), the LCD comprising a common electrode, a pixel electrode, a liquid crystal layer located between the common electrode and the pixel electrode, the liquid crystal layer having a plurality of impurity ions and a pixel utilized for displaying a gray scale, characterized in that the method comprises steps of: separating the impurity ions toward the common electrode and the pixel electrode to form an internal electric field in the liquid crystal layer; and providing a compensated common voltage for the common electrode, and providing a first pixel voltage and a second pixel voltage for the pixel electrode according to the gray scale, wherein the compensated common voltage is utilized to compensate the internal electric field so that a difference between the first pixel voltage and the compensated common voltage is equal to a difference between the second pixel voltage and the compensated common voltage; wherein the step of separating the impurity ions is done by providing an offset common voltage at the common electrode, and providing a first voltage and a second voltage at the pixel electrode so that a difference between the first voltage and the offset common voltage is unequal to a difference between the second voltage and the offset common voltage.
