Problems solved by technology

Due to the light-shielding effect of the black matrix 3, the aperture ratio of the color filter substrate 12 is greatly affected, resulting in a low transmittance.
In order for the display to meet the display brightness requirements, it is necessary to increase the brightness of the backlight, which will lead to increased power consumption

Embodiment 1

[0044] This embodiment provides a substrate provided with a black matrix 3 , the side of the black matrix 3 facing the backlight is a reflective surface 32 , and the backlight directed to the black matrix 3 can be reused after being reflected by the reflective surface 32 .

[0045] The structure of the substrate 1 provided with the black matrix 3, such as figure 2 As shown, it includes a substrate 1 , an R / G / B color block 2 and a black matrix 3 arranged on the substrate 1 . Wherein, the black matrix 3 includes a main body portion 31 and a reflective surface 32 disposed on the main body portion 31 . The main body part 31 and the reflective surface 32 can be made of the same material, or can be made of different materials. The reflective surface 32 is formed by a reflective material such as a metal material with high reflectivity, specifically silver, aluminum, etc. The reflective surface 32 has a high reflectivity and can reflect the backlight incident on its surface to other...

Embodiment 2

[0060] This embodiment provides a method for manufacturing a substrate, including: a step of forming a black matrix 3, the side of the black matrix 3 formed in the step of forming the black matrix 3 facing the backlight is a reflective surface 32, wherein the reflective surface 32 The function is to enable the backlight directed to the black matrix 3 to be reused after being reflected by the reflective surface 32 .

[0061] The aforementioned substrate is the color filter substrate 12 or the array substrate 11 , and the color filter substrate 12 is taken as an example for illustration in this embodiment. Such as figure 2 As shown, unlike the black matrix 3 in the prior art, which is entirely made of light-absorbing materials, the main body 31 of the black matrix 3 in this embodiment can still be made of light-absorbing materials, but its reflective surface 32 is made of high reflectivity Made of metal material. The reflective surface 32 is arranged on the side of the main p...

Embodiment 3

[0098] This embodiment provides a display device, which includes any one of the above-mentioned substrates provided with a black matrix 3 . The display device avoids the backlight loss caused by the light absorption effect of the black matrix 3 in the existing technology, and can achieve higher display brightness under the same power consumption, saving energy and electricity. The display device may be any product or component with a display function such as a liquid crystal panel, electronic paper, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

Abstract

The invention provides a substrate provided with a black matrix, a manufacturing method of the substrate and a display device. The transmittance can be effectively improved, so that the power consumption of the display is reduced. The invention provides the substrate provided with the black matrix. The face of the black matrix facing backlight is a reflective face, and backlight ejected to the black matrix is reflected by the reflective face and can be reused. The invention provides the manufacturing method of the substrate. The manufacturing method comprises the following step: forming the black matrix, wherein the face of the black matrix formed in the step of forming the black matrix is the reflective face, and the reflective face plays the role that backlight ejected to the black matrix is reflected by the reflective face and can be reused. The invention provides the display device which comprises any substrate provided with the black matrix. The substrate provided by the invention is used for improving the substrate of a display panel.

Description

technical field [0001] The invention relates to the display field, in particular to a substrate provided with a black matrix, a manufacturing method thereof, and a display device. Background technique [0002] The color filter substrate 12 is one of the important elements of a thin film transistor-liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD), and its basic structure is as follows: figure 1 As shown, it includes a substrate 1 , a black matrix 3 and an R / G / B color resist block 2 arranged on the substrate 1 . Due to the light-shielding function of the black matrix 3, the aperture ratio of the color filter substrate 12 is greatly affected, resulting in a lower transmittance. In order for the display to meet the display brightness requirements, it is necessary to increase the brightness of the backlight, which will result in increased power consumption. Contents of the invention [0003] The invention provides a substrate provided with a black...
