Embodiment Construction

[0019] In order to solve the problem of the large difference in brightness between the white sub-pixel area and the color sub-pixel area in the existing RGBW display substrate, an embodiment of the present invention provides a display substrate including a plurality of pixel units, and each pixel unit includes a plurality of colors. The area of ​​the sub-pixel and a white sub-pixel is the same, and the area of ​​the white sub-pixel is smaller than the area of ​​the color sub-pixel.

[0020] That is to say, by reducing the area of ​​the white sub-pixel area and reducing the brightness of the white sub-pixel area, the brightness of the white sub-pixel and the color sub-pixel area are approximately the same, thereby improving the uniformity of the brightness and avoiding the color distortion of the display screen. .

[0021] The ratio of the white sub-pixels to the color sub-pixels can be set according to specific conditions.

[0022] The specific embodiments of the present invention w...

Abstract

The invention provides a display substrate, a display panel and a display device. The display substrate comprises multiple pixel units, each pixel unit comprises multiple colorful sub-pixels and a white sub-pixel, the areas of the multiple colorful sub-pixels are the same, and the area of the white sub-pixel is smaller than that of each colorful sub-pixel. According to the display substrate, the display panel and the display device, the brightness of the white sub-pixel region is reduced through reducing the area of the white sub-pixel region, and the brightness of the white sub-pixel region is almost the same as the brightness of the colorful sub-pixel region, so that the uniformity of the brightness is improved, and the color distortion phenomenon of a display frame is avoided.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] At present, in image display devices such as liquid crystal panels (LCD) and organic electroluminescence display panels (OLED), red (R) sub-pixels, green (G) sub-pixels, and blue (B) sub-pixels form one The pixel unit displays the color image by controlling the gray value of each sub-pixel unit to mix the desired display color. Due to the low luminous efficiency of the three primary colors of RGB, it will restrict the product optimization of display devices composed of the three primary colors of RGB. Based on this, there are red (R) sub-pixels, green (G) sub-pixels, blue (B) sub-pixels and white (W) A pixel unit composed of sub-pixel units to improve the luminous efficiency of the RGB display. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of the structure of the ...
