Abstract
A driving method and a driving device of a display panel are provided. According to the display panel of the present application, subpixels adjacent in a row direction of the display array have different polarities, and subpixels adjacent in a column direction of the display array have different polarities. Adjacent subpixels have different voltages and are alternately arranged with a higher voltage or a lower voltage. The common electrode voltage required for operating picture of each frame is periodically changed by the driving device, with operational picture of two frames of the display panel taken as one driving cycle. With respect to different frames, different common electrode voltages are correspondingly applied to drive subpixels in the display array, reducing the occurrence rate of viewing angle color shift of display panel.
