Claim:
1. A driving method of a liquid crystal display apparatus, comprising: generating gray scale data of sub-pixels according to received image data; taking a plurality of sub-pixels as a processing unit, setting a gray scale voltage polarity signal corresponding to the gray scale data of a first sub-pixel of the plurality of sub-pixels as an initial value; and setting a gray scale voltage polarity signal corresponding to the gray scale data of an nth sub-pixel of the plurality of sub-pixels as a polarity signal opposite to a polarity signal obtained by summing the gray scale voltages corresponding to the gray scale data of previous n−1 sub-pixels, wherein n is increased from 2 to M, and M is the total number of sub-pixels included in the plurality of sub-pixels; outputting the gray scale data and the corresponding polarity signal of each sub-pixel to a source driver of the liquid crystal display apparatus; wherein the gray level voltage polarities of respective sub-pixels in the processing unit are set sequentially one by one.
