Patent ID: 8593383

Claim:
A liquid crystal display, comprising: a substrate; a plurality of data lines disposed on the substrate in a first direction for providing data signals; a plurality of scan lines disposed on the substrate in a second direction substantially perpendicular to the first direction for providing scan signals; a plurality of pixel units respectively disposed at the intersections of the data lines and the scan lines; and a pre-charge circuit comprising: a pre-charge potential; a pre-charge capacitor having a first electrode coupled to the pre-charge potential, and a second electrode; and a pre-charge switch having a first terminal for receiving a pre-charge signal, a second terminal coupled to one of the data lines, and a third terminal coupled to the second electrode of the pre-charge capacitor, wherein the pre-charge switch is turned on by the pre-charge signal before the scan signals turn on the pixel units, wherein the capacitance of the pre-charge capacitor is substantially equal to the capacitance of a storage capacitor of the pixel units, wherein the voltage of the data line is independent of the pre-charge potential, and the pre-charge potential is directly coupled with the pre-charge capacitor, wherein a common potential and the pre-charge potential change their respective polarities within a time period during which the pre-charge switch is turned on.
