Problems solved by technology

[0004] However, the increase of the graphic width of the black matrix will reduce the aperture ratio, resulting in a decrease in light transmittance and a decrease in contrast; a decrease in the cell gap (Cell Gap) will also reduce the light transmittance

Embodiment 1

[0026] This embodiment provides a color filter substrate, such as figure 1 As shown, it includes a substrate 1, a black matrix 2 and a color filter layer 3 disposed on the substrate 1, and also includes a light processing unit 4, which is disposed on the side of the black matrix 2 away from the substrate 1, and the light processing unit 4 The backlight light L that irradiates the light processing unit and has an angle θ with the substrate 1 within a set range can be refracted to enter the black matrix 2 .

[0027] By setting the light processing unit 4, the backlight light L that irradiates the light processing unit and has an angle θ with the substrate 1 within a set range can be refracted and then enter the black matrix 2, so as to prevent the backlight light L from passing through at the same time. The cross-color phenomenon of the display screen caused by the color films of more than two colors improves the cross-color problem when the display panel is displayed. In addit...

Embodiment 2

[0041] The present invention provides a color filter substrate, which is different from Embodiment 1, such as image 3As shown, on the basis of Embodiment 1, in this embodiment, a flat layer 5 is provided on the side of the light processing unit 4 away from the substrate 1 , and the refractive index of the light processing unit 4 is greater than that of the flat layer 5 . The arrangement of the flat layer 5 can make the surface of the color filter substrate facing the array substrate more flat, so that it is convenient to arrange spacers on the flat surface to support the array substrate and the color filter substrate of the box. The refractive index of the light processing unit 4 is greater than that of the flat layer 5, so that the backlight light incident on the light processing unit 4 through the flat layer 5 can be refracted and then deflected toward the black matrix 2, so that this part of the backlight light is irradiated to The black matrix 2 is on and absorbed by the ...

Embodiment 3

[0047] This embodiment provides a display panel, including the color filter substrate in any one of Embodiments 1-2.

[0048] By adopting the color filter substrate in any one of Embodiments 1-2, not only the problem of color crossover during the display of the display panel is improved, but also the aperture ratio of the display panel and the transmittance of backlight light are not reduced, and the performance of the display panel is improved. display effect.

[0049] The display panel provided by the present invention can be any product or component with a display function, such as a liquid crystal panel, a liquid crystal TV, a monitor, a mobile phone, a navigator, and the like.

Abstract

The invention provides a color-film substrate and a display panel. The color-film substrate comprises a substrate body, a black matrix arranged on the substrate body and a color-film layer and further comprises a light processing unit, wherein the light processing unit is arranged on the side, away from the substrate body, of the black matrix, and the light processing unit can make backlight irradiated to the light processing unit and forming an included angle with the substrate body in a set range refract and then irradiated into the black matrix. The color-film substrate can make the backlight forming the included angle with the substrate body in the set range refract and then irradiated into the black matrix so as to avoid backlight and a display picture color-crossing phenomenon caused by penetration of a color film with more than two colors by arranging the light processing unit, and accordingly the color-crossing problem during display of the display panel is improved. In addition, the light processing unit does not reduce the aperture opening ratio of the display panel while improving the color-crossing phenomenon and also does not reduce the transmittance rate of the backlight.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a display panel. Background technique [0002] At present, LCDs use color filters to achieve color display. Each pixel of the color filter is composed of three sub-pixels: red (R), green (G), and blue (B). When observing (for example, when the angle between the human eye and the display panel is 45° or 30°), since the backlight light may pass through the color filters of two colors at the same time, it may cause the problem of cross-color between the three sub-pixels. [0003] At present, the market is increasingly favoring high-resolution PPI display products. The higher the resolution, the higher the pixel density, and the more prone to cross-color problems. Under the condition that the technological level remains unchanged, the cross-color phenomenon is usually reduced by increasing the pattern width of the black matrix or reducing the ce...
