Abstract
A method for driving a liquid crystal display (LCD) is disclosed. The LCD includes a common electrode, a pixel electrode, and a liquid crystal layer having a plurality of impurity ions. The method includes: 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 common voltage for the common electrode, and providing a first compensation voltage and a second compensation voltage for the pixel electrode. The first compensation voltage and the second compensation voltage herein are utilized to compensate the internal electric field so that a difference between the first compensation voltage and the common voltage is equal to a difference between the second compensation voltage and the common voltage. Charge accumulation is formed intentionally, and then the first compensation voltage and the second compensation voltage are provided to correctly display images.
