Problems solved by technology

In the TFT-LCD of the existing structure, the light emitted from the LED light source is emitted through the light guide plate, and then first hits the array substrate. On the array substrate, the grid lines and data lines will block part of the light. When the light passes through the liquid crystal When the layer passes through the color filter substrate, the black matrix will block part of the light, so that the light passing through the display screen will be further reduced, resulting in a serious loss of the display brightness of the display screen.
[0003] In order to solve the problem of low light transmittance, in the prior art, the DBEF brightness enhancement film produced by 3M company is usually used to improve the light transmittance.
However, due to the high price of the product, the processing cost of the final product of the liquid crystal display is increased.

Embodiment 1

[0030] Such as figure 1 As shown, the color filter substrate of this embodiment includes: a glass substrate 1, a black matrix 2 and a color pixel layer 3 are arranged on the surface of the glass substrate 1, and an insulating layer 4 is arranged on the black matrix 2 and the color pixel layer 3; The insulating layer 4 is made of organic materials. A light refraction unit 5 is embedded on the surface of the insulating layer 4 , and a flat layer 6 is arranged on the insulating layer 4 , and the flat layer 6 is transparent. The refractive index of the light refracting unit 5 is set to be greater than that of the insulating layer 4, so that refraction can occur when the light passes through the two media. The light refraction unit is set correspondingly to the position of the black matrix 2, so that the light below the black matrix can be refracted to the pixel opening area mainly through the refraction phenomenon, so as to improve the light transmittance.

Embodiment 2

[0053] Such as figure 2 As shown, the color filter substrate of this embodiment includes: a glass substrate 1, a black matrix 2 and a color pixel layer 3 are arranged on one surface of the glass substrate 1, and a flat layer 6 is arranged on the black matrix 2 and the color pixel layer 3;

[0054] The other surface of the glass substrate is provided with an insulating layer 4 having the same refractive index as the glass substrate 1, and the insulating layer 4 is embedded with a light refraction unit 5, and the refractive index of the light refraction unit is greater than that of the glass substrate 1 (that is, the insulating layer). Refractive index, the insulating layer 4 is provided with a flat layer 6 .

[0055] The specific light refracting unit is composed of two quarter lenses, the arcs of the two quarter lenses are oppositely arranged, and the opening direction formed by the two arcs faces the glass substrate 1 .

[0056] The calculation method of the arc radius R of t...

Abstract

The invention relates to a technical field of display, and especially to a high brightness color film substrate and a display apparatus. The color film substrate comprises: a substrate, wherein black matrixes and a color pixie layer are arranged on a surface of the substrate, an insulating layer is arranged on the black matrix and the color pixie layer, light refraction units are embed in a surface of the insulating layer, a flat layer is arranged on the insulating layer, and refractive index of the refraction unit is greater than that of the insulating layer. With the color film substrate and the display apparatus provided in the invention, an additional refraction unit can enable the light that emits to the black matrix to generate refraction, thereby more light emits from the pixel opening region, according to the invention, transmittance of the light is greatly improved, display brightness of the display is increased and user experience feeling is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a high-brightness color filter substrate and a display device. Background technique [0002] Usually, the main structure of TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) is composed of array substrate, color filter substrate, polarizer, backlight and liquid crystal. The backlight source includes components such as LED light source, light guide plate, reflective layer and optical module; the array substrate includes structural layers such as grid lines and data lines; the color filter substrate includes structural layers such as black matrix and color pixel layer. In the TFT-LCD of the existing structure, the light emitted from the LED light source is emitted through the light guide plate, and then first hits the array substrate. On the array substrate, the grid lines and data lines will block part of the light. When the light ...
