Patent ID: 7683988

Claim:
A liquid crystal display, comprising: a plurality of data lines for conveying a data signal; a plurality of gate lines for providing a driving signal; and a plurality of pixels, each pixel comprising: a switching unit, responsive to the driving signal from a gate line, for admitting the data signal from a data line; a first common electrode for providing a first common voltage signal; a second common electrode for providing a second common voltage signal; a pixel electrode, electrically connected to the switching unit, for driving a liquid crystal layer within the pixel based on the admitted data signal and the first common voltage signal; a first liquid crystal capacitor having a first end electrically connected to the first common electrode, and a second end electrically connected to the pixel electrode; an coupling capacitor having a first terminal and a second terminal, wherein the first terminal is electrically connected to the pixel electrode; an adjustment capacitor having a first end electrically connected to the second common electrode and a second end connected to the second terminal of the coupling capacitor; and a second liquid crystal capacitor having a first end electrically connected to the first common electrode, and a second end electrically connected to the second terminal of the coupling capacitor, for driving the liquid crystal layer based on the admitted data signal, the first common voltage signal and the second common voltage signal.
