Patent ID: 8436849

Claim:
A circuit for driving a liquid crystal display device comprising: a liquid crystal panel having a plurality of pixel regions that display an image; a timing controller that generates one flicker preventive signal and a plurality of clock signals and gate control signals to control driving timing of a gate driver; a gate pulse modulation unit that logically operates the one flicker preventive signal and the plurality of clock signals from the timing controller to generate a plurality of flicker preventive signals, and modulating a gate high voltage from the timing controller according to each of the plurality of flicker preventive signals generated thus to generate a plurality of modulated gate on voltages; a level shifter unit that changes the plurality of clock signals from the timing controller according to the plurality of modulated gate on voltages from the gate pulse modulation unit and a gate low voltage from the timing controller to generate a plurality of level shifted and modulated clock signals; and a gate driver that drives gate lines on the liquid crystal panel according to the a plurality of level shifted and modulated clock signals.
