Abstract

The invention discloses a driving method of a display panel, a driving device of the display panel and a display device. Two rows of adjacent sub-pixel groups are connected with the same data line and are respectively connected with one scanning line, each sub-pixel group comprises two sub-pixels, the two sub-pixels are connected with the same scanning line and the same data line, and the two sub-pixels are connected with the same scanning line and the same data line. The storage capacitors of the two sub-pixels are respectively connected with a first common electrode line, the storage capacitors of the two adjacent sub-pixels in the two rows of adjacent sub-pixel groups are connected with the same first common electrode line, and the pixel capacitor of each sub-pixel is connected with a common electrode on the opposite side of a pixel electrode; the polarity of data voltage on each data line is controlled to be switched when frame pixel driving is switched, and the polarity of a common electrode signal on each first common electrode line is controlled to be switched by taking four frame pixel driving as a driving period, so that half of the scanning lines and the common electrode lines are basically reduced by sharing the scanning lines and the first common electrode lines; the effective aperture opening ratio of the display panel is increased, and the penetration rate is improved.

Description

technical field [0001] The present application relates to the technical field of display panels, and in particular to a method for driving a display panel, a device for driving a display panel, and a display device. Background technique [0002] At present, large-size display panels require larger viewing angles to display. During the pixel driving process, the brightness of large viewing angles rapidly saturates with the voltage, resulting in a serious deterioration in viewing angle image quality contrast and color shift compared with front-view image quality. The usual way to solve the viewing angle deviation is to divide the sub-pixels of the display panel into main / sub-pixels, and give different driving voltages to the main and sub-pixels. This kind of design often requires the design of metal wiring or TFT components to drive the sub-pixels pixels, resulting in the sacrifice of the light-transmitting opening area, affecting the transmittance of the panel, and directly r...
