Patent ID: 7948602

Claim:
A method for driving a liquid crystal display (LCD) panel, wherein the LCD panel comprises a plurality of pixels, each of the pixels comprising: a pixel capacitor, a storage capacitor, and a thin film transistor (TFT) having a first electrode coupled to a first terminal of the pixel capacitor and a first terminal of the storage capacitor, the method comprising: applying a first common voltage and a second common voltage to a second terminal of the pixel capacitor and a second terminal of the storage capacitor, respectively, wherein the first common voltage and the second common voltage are two different fixed DC voltages and an absolute difference between the first common voltage and the second common voltage is based on a value in a voltage range corresponding to a transmittance range which indicates a pixel in a dark state substantially and is determined according to a minimum transmittance and a maximum transmittance of the LCD panel; if one of the pixels is a faulty pixel whose storage capacitor is short-circuited and is repaired by being electrically disconnected from a data line corresponding to the faulty pixel, applying the first common voltage and the second common voltage to the faulty pixel, making the faulty pixel in the dark state substantially.
