Patent ID: 8766961

Claim:
A method for driving a liquid crystal display (LCD), the LCD comprises a plurality of data lines, a plurality of gate lines, and a plurality of pixel units arranged as a matrix array, a plurality of data signals each having one of negative and positive polarities applied to the pixel units via a respective one of data lines, wherein the polarities of the data signals are inverted once at intervals of one frame and the polarities of the data signals corresponding to the pixel units at different columns are opposite to each other, the method comprising: a. analyzing and determining the polarities of an arbitrary one column of the pixel units as determining units, thereby defining a first polarity group with a same polarity and a second polarity group with a polarity opposite to the polarity of the first polarity group; b. dividing a current frame into at least two sub-frame periods, and sequentially applying corresponding data signals to a part of the whole pixel units that are arranged in same rows as the first polarity group in one of the at least two sub-frame periods, and then sequentially applying corresponding data signals to the other part of the whole pixel units that are arranged in same rows as the second polarity group in the other one of the at least two sub-frame periods; wherein after the corresponding data signals finish writing to the pixel units located in the same rows as one of the first polarity group and the second polarity group, a step of pre-charging the data lines sequentially follows.
