Patent ID: 8106869

Claim:
A liquid crystal display, comprising: a plurality of data lines parallel to each other; a data driver configured for driving the data lines and arranged at one side of the plurality of data lines; a plurality of pixel units; a first coupling line crossing the data lines without connecting to the pixel units thereby defining a plurality of coupling capacitors between the first coupling line and the data lines; a second coupling line crossing the data lines without connecting to the pixel units thereby defining another plurality of coupling capacitors between the second coupling line and the data lines; a position where the second coupling line is disposed being farther from the data driver than a position where the first coupling line is disposed; a common electrode layer; and a common voltage generator configured for applying at least one common voltage to the common electrode layer, and connected to the first and second coupling lines; wherein the common electrode layer is capable of receiving the at least one common voltage; the data driver is configured to apply a plurality of data signals to the data lines, the first and second coupling lines are capable of coupling the data signals on the data lines thereby generating an influence signal at the first and second coupling lines, and the common voltage generator receives the influence signal and then adjusts the at least one common voltage applied to the common electrode layer according to the influence signal.
