ABSTRACT:
An apparatus for driving a liquid crystal display that includes a normal driving interval for providing normal driving of the liquid crystal display with a real-data signal after a reset period, wherein the liquid crystal display includes a liquid crystal between pixel and common electrodes in which the liquid crystal is transitioned from a splay state into a bend state at a voltage difference between the pixel and common electrodes greater than a transition voltage. The apparatus includes a reset circuit for setting a voltage difference between the pixel electrode and the common electrode during the reset period to be larger than an average voltage of the real-data signal in said normal driving interval and a controller for controlling voltages that are supplied to at least one of the pixel electrode and the common electrode.
