Problems solved by technology

[0003] The present invention aims to provide a three-structure layer non-diffusion plate type laminated film for liquid crystal displays that can meet the requirements of the film for liquid crystal displays, and solves the problem that the existing film for liquid crystal displays has a plurality of films with independent structures that are laminated and connected together. The problem of high cost caused by forming together

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , figure 2 and image 3 , a three-layer diffusion-free laminated film for liquid crystal displays, comprising a first structural layer film 1, a second structural layer film 2 and a third structural layer film 3 arranged in sequence from top to bottom.

[0023] The first structural layer film includes a first structural layer film part base film 4 and a first structural layer film part micro-convex structure layer 5 arranged on the upper surface of the first structural layer film part base film. The base film of the film portion of the first structural layer has a thickness of 123 microns to 127 microns, preferably 125 microns. The base film of the film portion of the first structural layer is an optical grade PET film. The micro-convex structure layer of the first structural layer is formed by a continuous arrangement of severa...

Abstract

The invention relates to a three-structural-layer diffusion-free plate type laminating film for a liquid crystal display. The laminating film comprises a first structural layer film, a second structural layer film and a third structural layer film; the first structure layer film comprises a first structure layer film part micro-convex structure layer, a first structure layer film part base film and a first structure layer film part adhesive layer; the second structural layer film comprises a second structural layer film part prism layer, a second structural layer film part base film and a second structural layer film part adhesive layer; and the third structural layer film comprises a third structural layer film part structural layer, a third structural layer film part base film and a backcoating. The laminating film has the advantage that the requirement of the liquid crystal display film can be met through one film, and the problem that the cost is high due to the fact that an existing liquid crystal display film is formed by stacking and connecting a plurality of films of independent structures is solved.

Description

technical field [0001] The invention relates to an optical film, in particular to a three-layer diffusion-free laminating film for a liquid crystal display. Background technique [0002] With the popularization of liquid crystal display technology, the demand for its backlight module and its related optical films is also increasing. The three film structures of diffuser plate, 90-degree brightness enhancement, 0-degree brightness enhancement, and diffusion film that were initially adopted have gradually been adopted. Two or even one multi-layer composite diaphragm is replaced. With the increasing size, the requirement for stiffness becomes higher, the product is thinner and the assembly line requires the diaphragm assembly to be more and more simplified. DOP+DP (Diffusion Sheet fit to add light + diffuser plate), POP+DP (brightness added to add light + diffuser plate), P+P+DP (brightness added + lightening + diffuser plate). Existing DOP, POP, P+P combination diaphragms bas...
