Claim Text:
1. A polarity inversion driving method for inversion of polarity of pixels on a liquid crystal panel, comprising: generating a polarity inversion reference signal for reflecting selection of polarity of each row of pixels on the liquid crystal panel; generating a control signal comprising control levels generated in m frames, where m is an integer higher than or equal to two, wherein width of the control level in each of the m frames is gradually increased in chronological order from zero to be a time length of one frame, wherein the width of the control level is increased once every r frames and a time duration for scanning s rows is increased every time until the width of the control level is equal to the time length of one frame, where r is an integer higher than or equal to one and s is an integer higher than or equal to one; or the width of the control level in each of the m frames is gradually decreased in chronological order from the time length of one frame to zero; and generating a polarity inversion signal from the polarity inversion reference signal and the control signal so as to complete a polarity inversion gradually in a time period of a plurality of frames.
