Claim 15:
16. The display device according to claim 14, wherein before the step of obtaining the refresh frequency of the current frame image, the processor is further configured to perform following steps of:
adjusting, when multi-frame images are displayed on the display device, the common voltage of the pixels in the second vertical blank interval at the preset refresh frequency of the display device;
detecting a flicker frequency of the multi-frame images;
obtaining a common voltage that causes the flicker frequency of the multi-frame images to be within a preset flicker frequency range, and taking the common voltage that causes the flicker frequency of the multi-frame images to be within the preset flicker frequency range as the target common voltage at the preset refresh frequency of the display device;
adjusting the preset refresh frequency of the display device, and returning to perform the step of adjusting, when the multi-frame images are displayed on the display device, the common voltage of the pixels in the second vertical blank interval at the preset refresh frequency of the display device so as to obtain a plurality of target common voltages at a plurality of different preset refresh frequencies; and
establishing the correspondence relationship between the different preset refresh frequencies and the plurality of target common voltages at the different preset refresh frequencies.
