Patent ID: 7804471

Claim:
A driving circuit of a liquid crystal display (LCD), the driving circuit comprising: a plurality of gate lines that are parallel to each other and that each extend along a first direction; a plurality of data lines that are parallel to each other and that each extend along a second direction substantially orthogonal to the first direction; a gate driving circuit connected to the gate lines; a data driving circuit connected to the data lines; a pre-charging voltage circuit comprising a pre-charging voltage generator and a plurality of thin film transistors, the pre-charging voltage circuit configured to provide a pre-charging voltage to each of the data lines before the gate driving circuit scans the gate lines; and a clock controller connected to the gate driving circuit, the driving circuit, and the pre-charging voltage circuit respectively; wherein the data lines are arranged in columns, the pre-charging voltage generator comprises a first input terminal, a second input terminal, a first output terminal connected to odd-column data lines, and a second output terminal connected to even-column data lines, and each thin film transistor comprises a gate electrode connected to the clock controller.
