Patent ID: 8502765

Claim:
A liquid crystal display comprising: a plurality of pixels, wherein each pixel comprises a thin film transistor; a gate line supplying a driving signal to a gate terminal of the thin film transistor of each pixel; a liquid crystal capacitor arranged in each pixel and connected to an output terminal of the thin film transistor in a corresponding pixel and defined by a pixel electrode, a common electrode facing the pixel electrode and a liquid crystal layer interposed between the pixel electrode and the common electrode; a sub-capacitor line aligned in parallel to the gate line; a sub-capacitor arranged in each pixel and connected between the output terminal of the thin film transistor in a corresponding pixel and the sub-capacitor line; and a driving circuit providing at least four voltages, selecting one of the voltages and supplying the selected voltage to the sub-capacitor line to drive the liquid crystal display in a state in which the liquid crystal capacitor is capacitively coupled to the sub-capacitor, wherein the driving circuit repeatedly supplies the four voltages to the sub-capacitor line in a sequence of a third voltage, a fourth voltage, a second voltage and a first voltage, wherein the first voltage>the second voltage>the third voltage>the fourth voltage.
