Color film substrate, color filter, display panel and display device

Abstract

The invention discloses a color film substrate, a color filter, a display panel and a display device. The color film substrate comprises a plurality of pixels distributed in an array mode. Each pixel at least comprises a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel, wherein the first sub-pixel is coated with first color light resistance, the second sub-pixel is coated with second color light resistance, the third sub-pixel is coated with third color light resistance, and light resistance in the fourth sub-pixel is formed by stacking any two of the first color light resistance, the second color light resistance and the third color light resistance. In this way,the color gamut range can be enlarged, the production process can be simplified, the production efficiency can be improved and the cost can be reduced.

Description

technical field [0001] The invention relates to the field of image display, in particular to a color filter substrate, a color filter, a display panel and a display device. Background technique [0002] In a color LCD panel, each pixel is composed of three liquid crystal sub-pixels, and the sub-pixels are respectively coated with red, green, or blue photoresists. In this way, light passing through different sub-pixels can display different colors on the screen. [0003] The traditional three-color pixel uses red, green, and blue as the primary colors. Each primary color has 256 intensities. By mixing the three colors, various colors of light can be formed. For example, yellow requires two types of light, red and green. For mixing, two sub-pixels need to be turned on at the same time, which has a narrower color gamut and higher power consumption. [0004] In the existing four-color pixel, a photoresist of another color is added on the basis of the original red, green, and b...

[0003] The traditional three-color pixel uses red, green, and blue as the primary colors. Each primary color has 256 intensities. By mixing the three colors, various colors of light can be formed. For example, yellow requires two types of light, red and green. Mixing, you need to turn on two sub-pixels at the same time, this method has a narrower color gamut and higher power consumption

[0004] In the existing four-color pixel, a photoresist of another color is added on the basis of the original red, green, and blue primary color photoresists to form four photoresists, and the four colors are mixed to form various colors. light, but due to the addition of a color photoresist, the process is complicated, the production efficiency is reduced, and the cost of materials is increased
