Patent ID: 7961166

Claim:
A driving method of the liquid crystal display device including a liquid crystal display panel according to a horizontal 2-dot inversion system comprising: detecting data corresponding to gray level values in which a dominant polarity is generated; shifting a polarity of the data in which the dominant polarity is generated in a horizontal direction and supplying the data to data lines of a liquid crystal display panel; and sequentially supplying a scanning pulse to gate lines crossing the data lines, wherein the polarity of the data shifts to a left side or right side in the horizontal direction in response to the dominant polarity signal, wherein a number of a positive polarity of the data becomes equal to a number of a negative polarity of the data for each data line, wherein the dominant polarity is a particular polarity which is generated in the horizontal direction for more liquid crystal cells than the opposite polarity in the data inputted to the liquid crystal panel.
