Abstract
A kind of shading glue sandwich construction, there is light shield layer and release layer, it is characterized in that, the adhesive layer is lower according to upper to include upper mould release membrance and lower mould release membrance, is fixed and pasted by double faced adhesive tape between the upper mould release membrance and lower mould release membrance；The light shield layer bottom surface is covered with single silicon mold paper.The utility model can effectively solve narrow frame backlight diaphragm and shading release problem on the premise of the shading performance of adhesive tape is not influenceed when being removed in subsequent handling, prevent shading rubber belt and backlight glue frame from separating.
Description
Technical field
A kind of shading glue sandwich construction is the utility model is related to, is hidden more particularly to one kind of electronic product backlight module
Optical cement sandwich construction.
Background technology
Backlight module is one of key part and component of liquid crystal display panel, and function is that well-off brightness is equal with distribution
Even light source, it can normally show image.With the continuous development and innovation of lcd technology, liquid crystal display is towards ultra-thin
The direction of narrow frame is developed, and accordingly, being evenly distributed for brightness and light source to backlight module proposes higher technical requirements.
Existing shading glue typically sets using black shading glue and above shading glue a PET mould release membrances, such a structure, and PET film is uncovered
Easily drive shading rubber belt and backlight glue frame separation afterwards, especially for narrow frame backlight module, have it is higher uncover fraction defective,
Cause unnecessary waste.
The content of the invention
The purpose of this utility model is in view of the shortcomings of the prior art, and provides release effect preferably a kind of shading glue
Sandwich construction.
The utility model is achieved through the following technical solutions.
A kind of shading glue sandwich construction, there is light shield layer and release layer, it is characterized in that, the release layer according to upper under include
Upper mould release membrance and lower mould release membrance, fixed and pasted by double faced adhesive tape between the upper mould release membrance and lower mould release membrance；The light shield layer bottom
Face is covered in the light shield layer covered with single silicon mold paper, the release layer by adhesive.
Further, the off-type force of the upper mould release membrance is more than lower mould release membrance off-type force more than 20 grams.
Further, the integral thickness of the release layer is not higher than 0.04mm.
Further, the release layer is one kind in PE mould release membrances, PET mould release membrances, PC mould release membrances, OPP mould release membrances.
The utility model has the advantages that：
A kind of shading glue sandwich construction of the present utility model, mould release membrance and lower mould release membrance on release layer is respectively equipped with, on
Mould release membrance and lower mould release membrance are formed by adhered by double sided plaster, and release layer is covered in the light shield layer by adhesive.Pasting
On backlight module and when being removed in subsequent handling, lower mould release membrance off-type force is less than upper mould release membrance off-type force, can more added with
Effect solves narrow frame backlight diaphragm and the release problem of shading, prevents shading rubber belt and backlight glue frame from separating.
Brief description of the drawings
Fig. 1 is the shading glue sandwich construction side view of embodiment 1.
Wherein：1 is light shield layer, and 2 be release layer, and 3 be single silicon mold paper, and mould release membrance on 21,22 be lower mould release membrance, and 23 be double
Face glue.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is further described in detail, should
Understanding, the case described herein that is preferable to carry out is merely to illustrate and explained the utility model, and without with limiting this practicality newly
Type.
Embodiment 1：
A kind of shading glue sandwich construction, its structure is as shown in figure 1, shading glue sandwich construction has light shield layer 1 and release layer
2, release layer 2 is lower according to upper to include upper mould release membrance 21 and lower mould release membrance 22, by double between upper mould release membrance 21 and lower mould release membrance 22
Face glue 23, which is fixed, to be pasted；Simultaneously in light shield layer bottom surface covered with single silicon mold paper 3.Release layer 2 is covered in shading by adhesive
Layer 1.
As the improvement of the present embodiment, the off-type force of upper mould release membrance is more than lower mould release membrance film off-type force more than 20 grams.
As the improvement of the present embodiment, the integral thickness of release layer 2 is not higher than 0.04mm.
As the improvement of the present embodiment, release layer 2 is in PE mould release membrances, PET mould release membrances, PC mould release membrances, OPP mould release membrances
It is a kind of.
Wherein, light shield layer 1 is made up of one layer of black ink, and for black ink layer thickness within 0.02mm, light shield layer 1 is another
The each one layer of adhesive being made up of acrylate pressure sensitive adhesive of coating in side, the thickness of the adhesive of light shield layer both sides 0.15mm with
Interior, both sides adhesive and light shield layer thickness ratio are 0.3:1；
The sticking area of upper mould release membrance 21 is whole glue frame, and the sticking area of lower mould release membrance 22 is glue frame source ends, can
Save material
Expect to keep preferable adhesion while cost.The integral thickness of the release layer 2 of the utility model design is not higher than
0.04mm, after fixing stickup by double faced adhesive tape 23 between upper mould release membrance 21 and lower mould release membrance 22, it is difficult to find by visual observation, meets
The lightening requirement of electronic display unit.
The specific process that the utility model is made in production using die-cutting process is as follows：
Upper mould release membrance is first cut out to the position being bonded with light shield layer, then unwanted waste material excluded.
First lower mould release membrance is cut out required position is bonded in source ends with light shield layer, then unwanted waste material is arranged
Fall.
Double faced adhesive tape in fitting, cut out inside casing and ear position（Handle）, then exclude inside casing and ear waste material.
Mould release membrance is bonded above upper step finished product, cuts out housing size, waste material of draining, product turns note winding, entirely
Examine outward appearance.
It can be seen from above-described embodiment that the utility model uses up and down, mould release membrance, lower mould release membrance fit in backlight mould
Group source ends,
Design of the release layer through special stick, lower mould release membrance off-type force are less than upper mould release membrance off-type force, can be with more efficient
Solve narrow frame backlight diaphragm and the release problem of shading, prevent shading rubber belt and backlight glue frame from separating.Enable adhesive tape
Good adhesion is kept for a long time, and its shape can be processed adjustment as needed, suitable for electronic product backlight module
Paste.
For certain above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this
The people of technology can understand content of the present utility model and implement according to this, and protection model of the present utility model can not be limited with this
Enclose.The modification that all Spirit Essences according to the utility model main technical schemes are done, it should all cover in guarantor of the present utility model
Within the scope of shield.
