Problems solved by technology

[0004] However, under poor design or process variation of such pixels, the problem of large viewing angles will occur. The reason is that when viewed from the side with a large viewing angle, there is a certain color that is displayed darkly.
For the blue pixel, the bias voltage of the blue pixel is low at the middle and low gray level (Gray Level), which causes the brightness of the blue sub-pixel area to turn on later
In the R / G / B three-color pixel design, the voltage divider switches are all connected to the same common electrode line. This design cannot be adjusted for a certain color to improve the phenomenon of large viewing angle deviation. Therefore, a new pixel circuit design needs to be proposed to solve the problem. Such problems

Abstract

A pixel-related circuit and a display panel are provided. The pixel-related circuit includes a plurality of pixel groups arranged in an array. The pixel group includes several pixel cells. Each pixel cell includes a first switch, a second switch, a voltage-dividing switch, and a common electrode line.

Description

technical field [0001] The present application relates to the display field, and relates to a common electrode line and a pixel circuit, in particular to a pixel circuit and a display panel. Background technique [0002] The display panel is provided with multiple pixels, and each pixel is composed of at least three sub-pixels with different colors. When each pixel is composed of three sub-pixels with different colors, the three sub-pixels are red sub-pixel R, green sub-pixel G and blue sub-pixel B, when the display panel needs to display a certain color, by adjusting R, G , The grayscale values ​​of the B sub-pixels can be combined into the desired color to present a colorful picture. [0003] In order to achieve the low color shift (LCS) specification of the Vertical Alignment (VA) mode display, one of the methods is to adopt a resistor divider pixel design method. This design method divides the pixel into two areas, the main pixel area and the sub-pixel area. When the d...
