Fitting method for membranes and optical membrane set

Abstract

The invention discloses a fitting method for membranes and an optical membrane set. The fitting method of the membranes comprises the following steps that S1, the bottom-layer membrane is placed on afitting platform and positioned; S2, the top surfaces of hanging lugs are coated with glue; S3, the last-layer membrane is laminated and positioned; S4, the second and third steps are repeated until the uppermost-layer membrane is positioned; S5, the glue is solidified. According to the fitting method, by using the characteristic that the hanging lugs of the membranes do not enter a display area of a liquid crystal module, the hanging lugs of the membranes are coated with the glue, and accordingly multiple membranes fit to form a membrane; the height limit of the folding edge of a backplate can be removed so that the liquid crystal module can be lighter and thinner, the technical requirements are met, base materials of the membranes do not need to be wasted, the stiffness of the membranesafter fitting is good, the combination of the membranes is flexible, and the membrane requirements of a complex backlight module can be met. Meanwhile, the membranes only need to be laid once in the assembly process of the liquid crystal module, the production process is simplified, and the reliability of the liquid crystal module is improved.

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...

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
