摘要： The present application provides a display device driving method and a display device. In the display device driving method, when optimal common voltages of other grayscales are determined using an optimal common voltage of a standard grayscale, and when grayscale shift occurs in the other grayscales, the optimal common voltages of the other grayscales are corrected, so that correct common voltages can be adopted when the display device is driven, and problems such as screen flicker caused by the grayscale shift in the display device are prevented.

摘要： The present invention discloses a display panel grayscale compensation method, a grayscale compensation device, and a grayscale compensation system. The grayscale compensation method, by acquiring at least one set of image data corresponding to bonding point grayscale values of the display panel, and by dividing the display panel into a main display region and sub-display regions through the image data, can determine grayscale compensation values corresponding to pixels in the sub-display region according to the average gamma value of each sub-display region, which can increase precision of a single grayscale compensation of the pixels in the display panel.
