Problems solved by technology

Since the included angle between the upper and lower prisms is fixed, the versatility of the product is not good. It can be used on one model, but cannot be used on another model because of Moore interference.
At this time, it is necessary to redevelop to adjust the angle of the product or the product itself to cut the angle, which is a waste of manpower and material resources.
In addition, linear prisms are prone to rainbow patterns, easy to absorb with the upper polarizer, and poor wear resistance of the product, resulting in low assembly yield and other problems.

Embodiment 1

[0019] See attached figure 1 As shown, a kind of multi-layer laminated film in the present embodiment comprises the first prism layer 1 and the second prism layer 2, and the second prism layer passes between the first prism layer 1 and the second prism layer 2 The non-prism structure array surface of the layer is coated with adhesive 3 and bonded together. The above-mentioned adhesive 3 can be transparent, or it can be a fog surface formed by adding particles in the middle. Generally, the thickness of the adhesive is 1-2. 5um, the haze is 0-50%.

[0020] In this embodiment, the line connecting the prism valley bottoms of the first prism layer 1 is a straight line; part of the line connecting the prism valley bottoms of the second prism layer 2 is a wavy curve, and the other part is a straight line. The included angle between the direction of the prism valley bottom of the first prism layer 1 and the direction of the prism valley bottom of the second prism layer 2 is β, and it...

Embodiment 2

[0029] like figure 2 As shown, this embodiment proposes a multilayer laminated film, which includes a first prism layer 1 and a second prism layer 2, and the second prism layer passes between the first prism layer 1 and the second prism layer 2 The non-prism structure array surface of the layer is coated with adhesive 3 and bonded together. The above-mentioned adhesive 3 can be transparent, or it can be a fog surface formed by adding particles in the middle. Generally, the thickness of the adhesive is 1-2. 5um, the haze is 0-50%.

[0030] The line connecting the prism valley bottoms of the first prism layer 1 is partly a wavy curve and the other part is a straight line; the line connecting the prism valley bottoms of the second prism layer 2 is a straight line. The included angle between the direction of the prism valley bottom of the first prism layer and the direction of the prism valley bottom of the second prism layer is β, and its range is 1°≤β≥179°. Because the connec...

Abstract

The invention discloses a multilayer laminated film, which comprises a first prism layer and a second prism layer. The first prism layer and the second prism layer are bonded together by coating an adhesive on a non-prism structure array surface of the second prism layer. At least one prism valley bottom connecting line of the first prism layer or the second prism layer is a wavy curve. The included angle beta between the prism valley bottom trend direction of the first prism layer and the prism valley bottom trend direction of the second prism layer is larger than or equal to 1 degree and smaller than or equal to 179 degrees. The included angle beta between the bottom directions of the prisms of the first prism layer and the second prism layer is variable, so that the molar interference between the prisms and the pixel points of the liquid crystal display can be effectively overcome, and the material waste caused by corner cutting of a laminated film product is reduced.

Description

technical field [0001] The invention relates to the field of optical thin films, in particular to a multilayer laminated film. Background technique [0002] The bonding film in the LCD backlight module has the advantages of high brightness, convenient assembly and high yield. At present, the angle between the upper and lower layers of prisms used in the laminating film in liquid crystal displays is fixed, such as the angle between the two layers of prisms in patent CN201310058308 is vertical, and the angle between the two layers of prisms in patent CN201611096522 It is 45-135°. Because the two layers of prisms are straight lines, and the angle between the two layers of prisms is fixed, it is easy to cause the problem of Moore interference. In order to solve the problem of Moore interference, the bonding film is generally adjusted, such as rotating the whole product by an angle , but it will change the product picture and derive new models. Since the angle between the uppe...
