Driving method and device of display panel and display device

Abstract

The invention discloses a driving method and device of a display panel and a display device. The display panel comprises a plurality of pixel groups. Each pixel group comprises two rows of adjacent sub-pixel groups, and storage capacitors of one sub-pixel in each sub-pixel group and storage capacitors of two non-adjacent sub-pixels in the other sub-pixel group are respectively connected with a first common electrode wire; the storage capacitors of one sub-pixel in each sub-pixel group and the storage capacitors of two adjacent sub-pixels in the other sub-pixel group are connected with the other first common electrode wire; each sub-pixel group and the sub-pixel groups in adjacent columns and adjacent rows are connected with one data line; the voltage polarities of two adjacent first common electrode wires are opposite. The driving method of the display panel comprises the following steps: controlling data voltage on each data line to perform positive and negative polarity switching by taking two frames as a driving period; and controlling the common electrode voltage level on each first common electrode line to perform high-low switching by taking two frames as a driving period.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a method and 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 resulting in an increase in the c...
