Laminating film for liquid crystal display and backlight module of liquid crystal display

Abstract

The invention discloses a laminating film for a liquid crystal display. The laminating film comprises an atomization layer film, a base film, a first prism layer film, a second prism layer film and athird prism layer film from top to bottom, and the atomization layer film, the base film, the first prism layer film, the second prism layer film and the third prism layer film are sequentially attached to one another through attaching glue. Moreover, the invention further discloses a backlight module of the liquid crystal display, and the backlight module comprises the laminating film for the liquid crystal display. According to the laminating film for the liquid crystal display, the brightness reaches the effect of two brightness enhancement films and two diffusion films, and the shielding property can also meet the requirements of the liquid crystal display module; and the laminating film can be in direct contact with glass of the liquid crystal display panel, it is guaranteed that interference and glare are avoided, the visual effect reaches the standard, the scratch resistance meets the assembly requirement, and the stiffness of a final product can meet the requirement of a large-size module.

Description

technical field [0001] The invention relates to a bonding film for a liquid crystal display and a backlight module of a liquid crystal display. Background technique [0002] With the development of TFT-LCD liquid crystal display technology, the requirements for the size and product stiffness of liquid crystal displays are gradually increasing, the products are required to be continuously thinned, and the requirements for assembly lines for diaphragm assembly are becoming increasingly simple. Lamination film production and application. The existing DOP, POP or P+P combination diaphragms basically adopt the form of one composite or two lightening + diffusion plates, and all structures require the use of diffusion plates. Moreover, these diaphragms need to be cut before they can be assembled and used, and one more layer of diaphragm needs to be cut one more time, which increases the packaging cost, not only increases the cost of materials, but also increases the cost of man-ho...

AI Technical Summary

Problems solved by technology

Moreover, these diaphragms need to be cut before they can be assembled and used, and one more layer of diaphragm needs to be cut one more time, which increases the packaging cost, not only increases the cost of materials, but also increases the cost of man-hours for assembling the diaphragm. lead to an increase in the total cost of the product

Repeated packaging, transportation and assembly will also bring many problems. For example, the product is easy to add scratches and foreign objects during the process of packaging, transportation and assembly. The adverse effects caused by the previous operation will cause subsequent operations. The decline in production and assembly yields will eventually lead to high costs

Therefore, there is a lack of product solutions for the existing backlight module and its related optical films that can not only ensure that the final product effect meets the requirements, improve brightness, anti-interference, scratch resistance, meet the stiffness requirements of large-scale applications, etc., but also reduce cost, thus widely used
