Problems solved by technology

Since the blue sub-pixel contributes little to the aperture ratio of the display panel, the main PS is generally set on the blue sub-pixel. For high pixel density (Pixels Per Inch, PPI) products, the sub-pixel size is small, and the BM surrounding the main PS is increased. The way of setting the distance will cause a big difference between the aperture ratio of the sub-pixel corresponding to the main PS and the aperture ratio of the sub-pixel corresponding to the auxiliary PS, such as figure 2 As shown, R, G, and B represent the red, green, and blue sub-pixel areas respectively. When the main PS is only set in the blue sub-pixel area, it is easy to appear horizontal lines, vertical lines or Diagonal display is bad
[0003] To sum up, in the prior art, the main PS is set on a sub-pixel of one color, resulting in a high density of main PS on the sub-pixel of this color, and poor display of horizontal, vertical or diagonal lines is prone to occur in a pure color screen.

Embodiment 1

[0035] Embodiment one, such as image 3As shown, R, G, and B in the figure respectively represent red, green, and blue sub-pixel regions, and the main spacer 1 is disposed in the red sub-pixel region and the blue sub-pixel region. Set N main spacers in the pixel structure, and set the main spacers in the red sub-pixel area and the blue sub-pixel area in equal proportions, that is, set N / 2 main spacers in the red sub-pixel area and the blue sub-pixel area respectively. Spacers, compared to only setting main spacers in sub-pixel areas of one color, can reduce the density of main spacers in sub-pixel areas of one color, thereby reducing the occurrence of horizontal and vertical lines in solid-color screens Or the risk of poor twill display, and the density of the main spacer in the red sub-pixel area and the blue sub-pixel area is consistent, and the corresponding display effect of the solid color screen of the corresponding color is consistent, which further improves the display...

Abstract

The invention discloses a pixel structure, a display panel and a display device and aims to lower risks of bad display effect with transverse lines, vertical lines or inclined lines under pure-color pictures so as to improve display quality of products and improve user experience. The pixel structure comprises subpixels different in color and spacers arranged in subpixel areas, and the spacers include main spacers which are arranged in the subpixel areas with at least two colors.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a pixel structure, a display panel and a display device. Background technique [0002] A liquid crystal display panel usually consists of an array substrate, a color filter substrate, and a liquid crystal layer filled between the two layers. The data lines and gate lines of the array substrate divide the array substrate into independent pixel units. Each pixel unit includes a thin film transistor unit (Thin Film Transistor, TFT) and pixel electrodes. The color filter (Color Filter, CF) substrate mainly Including a color filter, a black matrix (Black Matrix, BM) and a spacer (Photo Space, PS), the positions of the black matrix and the grid lines and data lines correspond to define sub-pixel units. The thickness of the liquid crystal layer (Cell Gap) is mainly controlled by the height of the PS. The PS is divided into the main PS and the auxiliary PS. The height of the...
