Claim 11:
12. The display device according to claim 9, wherein the refresh frequency of the current frame image is greater than the refresh frequency of the reference frame image, and the second vertical blank interval is smaller than the first vertical blank interval;
the processor is further configured to implement the step of adjusting the common voltage of all the pixels in the second vertical blank interval by:
in a frame-inversion-driving-mode, boosting the common voltage of the pixels in the second vertical blank interval if the current frame has the positive polarity; reducing the common voltage of the pixels in the second vertical blank interval if the current frame has the negative polarity;
in a point-inversion-driving-mode, boosting the common voltage of the pixels having the positive polarity in the second vertical blank interval, and reducing the common voltage of the pixels having the negative polarity in the second vertical blank interval;
in a row-inversion-driving-mode, boosting 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 is reduced;
in a column-inversion-driving-mode, boosting the common voltage of column pixels having the positive polarity in the second vertical blank interval, and reducing 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, boosting the common voltage of the pixels having the positive polarity in the second vertical blank interval, and reducing the common voltage of the pixels having the negative polarity in the second vertical blank interval.
