Embodiment 1

[0027] In this embodiment, a color filter substrate in a 55-inch full high definition (Full High Definition, FHD for short) curved liquid crystal television is taken as an example for illustration. The resolution of a full HD LCD TV is 1920×1080, that is, a total of 1080 rows and 1920 columns of pixel areas, and each pixel area is composed of 3 sub-pixel areas arranged side by side, so there are 5760 columns of sub-pixel areas on the color filter substrate.

[0028] The lateral width of all or part of the black matrix located on both sides of the color filter substrate is smaller than the lateral width of the black matrix located in the middle area of ​​the color filter substrate. The areas on both sides can usually account for 50% to 70% of the total area of ​​the color filter substrate, because in the prior art, due to the offset between the black matrix and the data lines, a total of 50% to 70% of the area on both sides of the curved display will be caused. The aperture rat...

Embodiment 2

[0038] This embodiment is basically the same as Embodiment 1, except that the color filter substrate provided in this embodiment is a color filter substrate in a 55-inch ultra high definition (Ultra High Definition, UD for short) curved liquid crystal TV. The resolution of ultra-high-definition LCD TV is 3840×2160, that is, there are 3840 rows and 2160 columns of pixel areas in total. Each pixel area is composed of 3 sub-pixel areas arranged side by side, so there are 11520 columns of sub-pixel areas on the color filter substrate.

[0039] Such as figure 2 As shown, in this embodiment, there are 5 black matrixes 2 on the left and right sides each with a lateral width of 32 microns, and they are evenly distributed in the 2880 black matrices 2 on the left and right sides respectively, and the remaining black matrices 2 (including The lateral widths of the black matrix in the middle area and the black matrix in the two side areas are both 33 microns. figure 2 Only the schemati...

Embodiment 3

[0043] An embodiment of the present invention provides a curved display device, which may be a 55-inch full high-definition curved liquid crystal TV, which includes an array substrate and the color filter substrate provided in the first embodiment above.

[0044] The curved display device may also be a 55-inch ultra-high-definition curved liquid crystal TV, which includes an array substrate and the color filter substrate provided in the second embodiment above.

[0045] Of course, the curved display device may also be a curved liquid crystal television of other sizes and models, or other curved display devices.

Abstract

The invention discloses a color filter substrate and a curved surface display device, which belongs to the field of display technology and solves the technical problem of low aperture ratio of existing curved surface displays. The color filter substrate includes: several sub-pixel areas arranged in an array; and a black matrix that separates each of the sub-pixel areas; wherein, in the lateral direction, all or part of the areas on both sides of the color filter substrate The lateral width of the black matrix is ​​smaller than the lateral width of the black matrix located in the middle area of ​​the color filter substrate. The invention can be used in curved display devices such as curved liquid crystal televisions and curved liquid crystal displays.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate and a curved display device. Background technique [0002] The curved display has a curved display. Since it can achieve the same distance from each pixel of the screen to the human eye, it can more realistically restore the real visual experience of the human eye, so it has stronger competitiveness compared with the traditional flat panel display. [0003] The manufacturing process of the curved surface display is to firstly manufacture the flat array substrate and the color filter substrate respectively, then box the array substrate and the color filter substrate to form a flat liquid crystal panel, and then bend the flat liquid crystal panel to form an inner panel. Concave curved LCD panel. Among them, the array substrate is provided with a number of criss-cross gate lines and data lines, and the sub-pixel areas separated by the gate lines an...
