Claim 2:
3. The method according to claim 1, wherein the refresh frequency of the current frame image is less than the refresh frequency of the reference frame image, and the second vertical blank interval is greater than the first vertical blank interval; and
said adjusting the common voltage of the pixels in the second vertical blank interval comprises:
in a frame-inversion-driving-mode, reducing the common voltage of the pixels in the second vertical blank interval if the current frame has a positive polarity; boosting the common voltage of all the pixels in the second vertical blank interval if the current frame has a negative polarity;
in a point-inversion-driving-mode, reducing the common voltage of the pixels having the positive polarity in the second vertical blank interval, and boosting the common voltage of the pixels with the negative polarity in the second vertical blank interval;
in a row-inversion-driving-mode, reducing the common voltage of row pixels having the positive polarity in the second vertical blank interval, and boosting the common voltage of row pixels having the negative polarity in the second vertical blank interval;
in a column-inversion-driving-mode, reducing the common voltage of column pixels having the positive polarity in the second vertical blank interval, and boosting the common voltage of column pixels having the negative polarity in the second vertical blank interval; and
in a line-one-and-line-two-inversion-driving-mode, reducing the common voltage of the pixels having the positive polarity in the second vertical blank interval, and boosting the common voltage of the pixels having the negative polarity in the second vertical blank interval.
