Embodiment 1

[0039] In Example 1, such as image 3 As shown, the black matrix is ​​a striped black matrix 1 arranged in parallel, and each striped black matrix 1 is arranged in parallel between each sub-pixel R, G, and B. The light-transmitting part 10 is opened on the strip-shaped black matrix 1 arranged in parallel, and the light-transmitting part 10 is a slit, and the light-transmitting part 10 is arranged along the direction in which the black matrix 1 extends, that is, the light-transmitting part 10 (slit) and the black The directions of the matrix 1 are the same, so that the backlight light can pass through the black matrix 1 and be diffracted.

[0040] Preferably, the light-transmitting portion 10 is located in the middle of the black matrix, that is, a slit is opened in the middle of the strip-shaped black matrix 1 to form the light-transmitting portion 10, so that the diffracted light can completely cover the light-transmitting portion 10 black matrix areas on both sides, so as t...

Embodiment 2

[0043] In Example 2, such as Figure 4 As shown, the black matrix 1 is grid-shaped, and 1 includes a plurality of striped first black matrix 11 and a plurality of striped second black matrix 12, and the first black matrix 11 and the second black matrix 12 are vertically intersected, The first black matrix 11 is arranged vertically, and the second black matrix 12 is arranged horizontally. The light-transmitting part 10 is a slit, which is disposed on the first black matrix 11 and / or the second black matrix 12, and is disposed along the extending direction of the black matrix where it is located.

[0044] In this example, if Figure 4 As shown, the first black matrix 11 and the second black matrix 12 are provided with light-transmitting parts 10 (slits), and the light-transmitting parts 10 are respectively arranged along the extending direction of the first black matrix 11 and the second black matrix 12 . In this way, both the first black matrix 11 and the second black matrix ...

Embodiment 3

[0048]The difference between Embodiment 3 and Embodiment 2 lies in that the shape and position of the light-transmitting portion 10 are different. In Example 3, such as Figure 5 As shown, the light-transmitting part 10 is an opening area, and is arranged at the intersection of the first black matrix 11 and the second black matrix 12, so that both the first black matrix 11 and the second black matrix 12 can be blanked.

[0049] It should be noted that the shape of the opening area (light-transmitting portion 10) is related to the shape of the sub-pixel, for example, if the sub-pixel is rectangular or square, the light-transmitting portion 10 is a square opening area, and if the sub-pixel is hexagonal shape, the transparent portion 10 is a triangular opening area.

[0050] In Embodiment 3, an opening area is opened on the black matrix to realize orthogonal diffraction, and the dispersion formed by the orthogonal diffraction can be compensated by the adjacent orthogonal diffrac...

Abstract

The invention provides a black matrix, a colored film substrate and a display device. A light transmission part is formed in an existing black matrix so that backlight light penetrates through the black matrix to be diffracted, and furthermore, a diffraction effect is generated; other regions of the black matrix are shielded by diffraction light generated by the light transmission part on the black matrix and blanking of the black matrix is realized, so that a screen door effect is eliminated, and the resolution ratio and definition of an image are improved. Furthermore, the light transmission part is arranged on the black matrix and white light, which is previously absorbed by the black matrix, can penetrate through the light transmission part, so that the transmission rate of the whole body of a liquid crystal panel can be improved, the brightness of a display module is improved, the power consumption of a backlight light source is reduced, and the relatively good display effect is realized.

Description

technical field [0001] The invention relates to the technical field of semiconductor equipment manufacturing, in particular to a black matrix, a color filter substrate and a display device. Background technique [0002] Existing color filter substrates such as figure 1 As shown, it includes a black matrix (BM) and a red color film R, a green color film G, and a blue color film B. The BM is located between the adjacent red color film R and the green color film G, and the adjacent green color film G and the Between the blue color filter B, between the red color filter R and the blue color filter B, the black matrix area in the color filter substrate is the gap between the sub-pixels. [0003] Therefore, the image displayed on the LCD (Liquid Crystal Display) with a lower resolution will have obvious black grids or black stripes, like an image viewed through a screen door. door effect". [0004] With the gradual improvement of display screen resolution, the black matrix area...
