Method for laminating diaphragms and optical diaphragm group

Abstract

The invention discloses a laminating method of diaphragms and an optical diaphragm group. The bonding method of the diaphragm includes the following steps: S1: placing the bottom diaphragm on the bonding platform and positioning it; S2: coating the top surface of the lug with colloid; S3: stacking the upper diaphragm and positioning it; S4: Repeat steps S2 and S3 until the positioning of the uppermost diaphragm is completed; S5: Curing the colloid. This bonding method takes advantage of the feature that the lugs of the diaphragm do not enter the display area of ​​the liquid crystal module, and coats the lugs of the diaphragm with colloid, so that multiple diaphragms are bonded to form a diaphragm, which can relieve the pressure on the diaphragm. The height limit of the folded edge of the back plate makes the liquid crystal module lighter and thinner, which meets the process requirements, and does not need to discard the base material of the diaphragm. Film requirements for backlight modules. At the same time, during the assembly process of the liquid crystal module, it is only necessary to lay the diaphragm once, which simplifies the production process and improves the reliability of the liquid crystal module.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a lamination method of diaphragms and an optical diaphragm group. Background technique [0002] With the continuous development of TV technology, ultra-thin and ultra-narrow bezels have become a wider demand, so there are higher requirements for the process of LCD modules. The liquid crystal module includes a backlight module and a liquid crystal display, and the backlight module includes a direct-type backlight module and an edge-type backlight module. Take the edge-lit backlight module as an example, such as figure 1 As shown, the backlight module mainly includes: light guide plate 3', optical film set 4', LED light source assembly 2', back plate 1', middle frame 5' and so on. Wherein the optical film set 4' includes a variety of different optical films such as a diffuser, an enhancement film, a DBEF, a reflector, etc., and the optical film includes a base mat...

AI Technical Summary

Problems solved by technology

However, in this method, the substrate between adjacent functional layers needs to be discarded to avoid the colloid from affecting the optical effect of the laminated film, resulting in poor stiffness of the optical film and poor positioning between the functional layers. Poor, prone to membrane delamination

There are fewer types of laminated films produced by film manufacturers, and it is difficult to meet the film requirements of complex backlight modules
