Problems solved by technology

[0002] At present, large-size display panels require larger viewing angles. During the pixel driving process, the brightness of large viewing angles rapidly saturates with voltage, resulting in a serious deterioration in viewing angle image quality contrast and color shift compared to 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 panel transmittance, directly resulting in an increase in the cost of the backlight

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 driving method of the display panel comprises the following steps: controlling data voltage on each data line to perform positive and negative polarity switching once every two frames; 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 device technology, and in particular, to a driving method, device and display device of a display panel. Background technique [0002] At present, large-size display panels require a large viewing angle to display. During the pixel driving process, the brightness of the large viewing angle saturates rapidly with the voltage, resulting in a serious deterioration of the viewing angle image quality contrast and the color shift compared to the 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 redesigning metal traces 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 causing the c...
