Problems solved by technology

[0003] In the prior art, in order to avoid arching and wrinkling of the reflector, thicker and more expensive reflectors are often used. This can solve the problem to a certain extent, but it increases the cost and weight of the entire liquid crystal module. and increase in size

Embodiment 1

[0024] like figure 1 Shown is a preferred embodiment provided by the present invention.

[0025] The reflection sheet 1 provided in this embodiment is used in a liquid crystal module to reflect light emitted by a light source in the liquid crystal module. As shown in the figure, the X direction is defined as the horizontal direction of the plane of the reflective sheet 1 and the Y direction is defined as the vertical direction of the plane of the reflective sheet 1 .

[0026] In order to uniformly reflect the light source, the reflector 1 in this embodiment is a planar body, on which there is a linear structure 12 that runs through the upper and lower end surfaces of the reflector 1, and the linear structure 12 can divide the reflector 1 into several interconnected The blocks together, that is, the linear structure 12 penetrates the upper and lower end surfaces of the reflective sheet 1 in the longitudinal direction, but in the plane direction, and does not penetrate the refl...

Embodiment 2

[0038] like figure 2 Shown is another preferred embodiment provided by the present invention.

[0039] The difference between this embodiment and Embodiment 1 is that the dotted lines in this embodiment include eight vertical dotted lines 121 and four horizontal dotted lines 122, wherein each horizontal dotted line 122 is respectively connected with two vertical dotted lines 121 to form an open body, In this way, the dotted line forms four openings, and these four openings are distributed symmetrically about the center of the reflection sheet 1 .

[0040] Specifically, the four opening-shaped bodies are distributed in two rows, and the openings of the opening-shaped bodies in each row have the same opening orientation, and the openings of the opening-shaped bodies in different rows face away from each other.

Embodiment 3

[0042] like image 3 Shown is another preferred embodiment provided by the present invention.

[0043] The difference between this embodiment and Embodiment 1 is that the dotted lines in this embodiment include two horizontal dotted lines 122 and eight vertical dotted lines 121, wherein each horizontal dotted line 122 is respectively connected with two vertical dotted lines 121 to form an open body, In this way, the dotted lines of the reflective sheet 1 form four vertical dotted lines 121 and two openings, which are symmetrically distributed on the reflective sheet 1 with respect to the center of the reflective sheet 1 .

[0044] Specifically, the openings of the two opening-shaped bodies have the same orientation and are arranged side by side, a vertical dotted line 121 on the opening-shaped body extends downward, and the other four vertical dotted lines 121 are arranged side by side and arranged below the two opening-shaped bodies.

Abstract

The invention relates to the technical field of liquid crystal displays, and discloses a reflective sheet, a liquid crystal module comprising the reflective sheet, and a liquid crystal display comprising the liquid crystal module. The reflective sheet is used for reflecting light emitted by a light emitting source in the liquid crystal module, the reflective sheet is a plane which is provided with a linear structure used for dividing the reflective sheet into multiple blocks which are connected into a whole, and the linear structure passes through an upper end face and a lower end face of the reflective sheet. The linear structure in the reflective sheet divides the reflective sheet, so that the large-size reflective sheet is divided into multiple small-size blocks which are connected into a whole, thus, the uniformity of the reflective sheet is maintained and the arching and wrinkling phenomena caused by expansion of the reflective sheet are avoided, the light reflected by the reflective surface is relatively uniform, the image effect of the liquid crystal module is improved greatly, the phenomenon of shadow does not appear in the image, furthermore, the cost, the weight and the thickness of the liquid crystal module can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a reflection sheet, a liquid crystal module including the reflection sheet and a liquid crystal display including the liquid crystal module. Background technique [0002] The reflective sheet is used in the liquid crystal module to reflect the light emitted by the light source in the liquid crystal module. As the size of the liquid crystal display continues to increase, the requirements for the reflective sheet are getting higher and higher, such as UX188 (thickness 0.188 mm), UX225 (thickness 0.225mm) and UX270 (thickness 0.270mm), etc. are used in small and medium-sized LCDs, but when used in large-sized LCDs, due to the thinness of the material, strength and stiffness Insufficient temperature and other reasons, the aging of the liquid crystal module or during the climate test, the reflective sheet will expand and arch, and the reflective sheet will wrinkle due t...
