Problems solved by technology

[0004] At present, there are many types of adhesive tapes in the industry and the adhesive systems of each tape are different. The hard adhesive with higher hardness has lower viscosity and poor attachment retention, which is not conducive to the application of product attachment. When applied to liquid crystal display devices, it is easy to cause damage to the backlight module. It is separated from the liquid crystal display module. If a better attachment and retention force is required, soft soft glue must be used, but the soft glue is easy to deform under high temperature or heavy pressure. Please refer to figure 2 As shown, the soft glue 131 of the double-sided adhesive tape 13 flows out due to high temperature or heavy pressure, and overflows into the microstructure 1111, that is, overflows into the viewing area of ​​the liquid crystal display module, which is surrounded by the double-sided adhesive tape 13 As a result, the liquid crystal display device will find bright lines when the backlight is turned on, resulting in poor visual effects
In order to improve the problem of glue overflow, although tapes with better cohesion can be used, the material cost of this type of tape is higher than that of other tapes of the same thickness, and it is not suitable for low-priced, high-quality products

Embodiment Construction

[0018] The technical means and effects used by the present invention to achieve the purpose will be described below with reference to the attached drawings, and the embodiments listed in the following drawings are only for auxiliary explanation, so as to facilitate the understanding of the review committee, but the technical means of this case are not Not limited to the listed drawings.

[0019] see image 3 The structure of an embodiment of the brightness enhancement film provided by the present invention is shown. The brightness enhancement film 20 includes a main body 21, and a prism structure 211 is provided on one side of the main body 21. The prism structure 211 is in the shape of multiple parallel strips The prism structure is provided with two grooves 212 in the prism structure 211. The grooves 212 can be cut or thermally melted, and can be formed together when cutting the brightness enhancement film 20, without additional manufacturing costs and When working, and the...

Abstract

The invention provides a brightness enhancement film and a liquid crystal display module with the same. The brightness enhancement film comprises a main body, one face of the main body is provided with a prism structure, the prism structure comprises at least one obstruction structure which can be a groove or retaining wall structure, the obstruction structure separates the prism structure into at least one first prism structure region and at least one second prism structure region, and a double sided tape is attached to the first prism structure region, thus, the obstruction structure obstructs the excessive glue of the double sided tape in the first prism structure region, and the excessive glue is prevented from flowing into the second prism structure region.

Description

technical field [0001] The invention relates to a brightness enhancement film and a liquid crystal display module with the brightness enhancement film, especially a brightness enhancement film which can prevent double-sided adhesive tape from overflowing into the viewing area of ​​the liquid crystal display module and the brightness enhancement film with the brightness enhancement film LCD module, so there is no need for special testing on the selection of double-sided tapes, and lower-cost double-sided tapes can also be used. Background technique [0002] The structure of the existing liquid crystal display device mainly includes a backlight module and a liquid crystal display module stacked on the backlight module. The backlight module includes two brightness enhancement films stacked from top to bottom, a diffusion sheet, a light guide plate A reflection sheet and a light source located at one end of the light guide plate, the liquid crystal display module includes an upp...
