Patent ID: 7129921

Claim:
A liquid crystal display (LCD), comprising: a liquid crystal panel having a plurality of pixels; a timing control circuit generating a gate clock signal and a plurality of control signals; a gray voltage generation circuit generating a first gray voltage in a first interval of the gate clock signal and a second gray voltage in a second interval of the gate clock signal in response to a voltage level of the gate clock signal and a plurality of reference voltages obtained by dividing a power supply voltage to a predetermined ratio, the first gray voltage having a magnitude greater than that of the second gray voltage; a gate driving circuit sequentially scanning the pixels row by row in response to the gate clock signal; and a source driving circuit generating a first driving voltage corresponding to the first gray voltage and a second driving voltage corresponding to the second gray voltage, wherein the first driving voltage is applied to the panel in the first interval of the gate clock signal and the second driving voltage is applied to the panel in the second interval of the gate clock signal.
