Embodiment 1

[0028] This embodiment provides a color filter substrate, such as image 3 As shown, a plurality of pixel units 3 are included, and each pixel unit 3 includes a plurality of primary color sub-pixels 37 and at least one color-mixing sub-pixel 38, and the color-mixing sub-pixel 38 is composed of multi-layered color filters of different colors.

[0029] Specifically, such as Figure 4 As shown, the red color film 21, the blue color film 22, and the green color film 23 respectively form the primary color sub-pixel 37; in addition, the blue color film 22 and the green color film 23 are stacked to form the cyan sub-pixel 35, and similarly, the red color film 21 It overlaps with the green color filter 23 to form a yellow sub-pixel 36 .

[0030] Among them, the color mixing sub-pixel 38 composed of multi-layered color filters of different colors supplements and enhances the primary color sub-pixel 37 to achieve a high color gamut and make the display more pure. The preparation metho...

Embodiment 2

[0032] This embodiment provides a color filter substrate, the color filter substrate includes a substrate 10, such as Figure 5 , Image 6 As shown, a plurality of pixel units 3 are included, and each pixel unit 3 includes a plurality of primary color sub-pixels 37 and at least one color-mixing sub-pixel 38, and the color-mixing sub-pixel 38 is composed of multi-layered color filters of different colors; wherein A black matrix area 12 is arranged around the primary color sub-pixels and mixed color sub-pixels, and the black matrix area 12 is composed of multi-layered color filters of different colors.

[0033] Specifically, such as Image 6 As shown, the black matrix region 12 is composed of a red color film 21 , a blue color film 22 , and a green color film 23 stacked together.

[0034] Preferably, the color filters of each layer in the black matrix area 12 are formed synchronously with the color filters of the same color as the pixel unit 3 . That is to say, in this embodi...

Embodiment 3

[0045] This embodiment provides a method for preparing a color filter substrate, including the step of forming color filters of different colors, wherein the color filters at some positions form primary color sub-pixels, and the color filters of different colors at some positions are stacked in multiple layers to form mixed colors sub-pixel.

[0046] by Image 6 The color filter substrate shown as an example, such as Figure 9 As shown, it specifically includes the following steps:

[0047] (1) Form a red color film 21 on the substrate 10, and use the first mask plate 4 to expose and develop;

[0048] (2) Form a green color film 23 on the red color film 21, and use the second mask plate 4 to expose and develop;

[0049] (3) Form the color blue color film 22 on the green color film 23, and adopt the third mask plate 4 to expose and develop, to obtain Image 6 The color filter substrate shown.

[0050] Among them, from Image 6 and Figure 9 It can be seen from the figure t...

Abstract

The invention provides a color film substrate and a manufacture method thereof, a display panel and a display device, pertaining to the field of display technology. Therefore, the problem that purple, green and yellow fail to achieve in a color gamut due to poor color mixture. The color film substrate comprises multiple pixel units, each comprising multiple primary-color subpixels and at least one mixed-color subpixel. The mixed-color subpixel is composed of color films of different colors which are stacked in multiple layers. The mixed-color subpixel is used for supplementing and augmenting the primary-color subpixels such that high colour gamut is achieved and display is purer. The color film substrate and the manufacture method thereof, the display panel and the display device have following beneficial effects: the manufacture method is used for changing a metal pattern plate of a color film without changing technology; cost is low; volume production is achieved; and the color film substrate is suitable for all kinds of display devices.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] In the prior art common red, green and blue (RGB) three-primary color liquid crystal display device, the color filter substrate such as figure 1 , figure 2 As shown, it includes a black matrix 1 formed on a substrate 10 and a pixel unit 3 defined by the black matrix 1. The pixel unit 3 includes three adjacent sub-pixel units (red sub-pixel 31, blue sub-pixel 31, and color sub-pixel 32, green sub-pixel 33), the sub-pixel unit is provided with a color film of a corresponding color (red color film 21, blue color film 22, green color film 23), the sub-pixel unit of the color film substrate and the array substrate The positions of the sub-pixel units are in one-to-one correspondence for realizing color display. [0003] The inventors have fou...
