Abstract
The utility model discloses a OCA optical cement, be equipped with in proper order heavily from type membrane, optics glued membrane, gently from the type membrane including from the top down, heavily be equipped with MARK point respectively on four L angles of type membrane. The utility model has the advantages of simple structure, through heavily being greater than optics glued membrane size from type membrane size with making man -hour, heavily fixing a position from the epimembranal increase MARK of type simultaneously and marking, to gently increase simultaneously from the type membrane in addition, and be greater than heavily from the type membrane, it is light from the type membrane with heavily from keeping the better effect of peeling off between the type membrane to guarantee like this that the optics glued membrane is in all the time, optics glued membrane edge with light from the type membrane and the profile that leaves that heavily leaves the type membrane contact all the time and does not take place the adhesion, heavily fix a position unusual problem when the epimembranal MARK of type point can the laminating of accurate solutions TP.
Description
Technical field
This utility model relates to OCA optical cement technical field, particularly relates to a kind of OCA optical cement.
Background technology
Optical cement is the double-sided adhesive of high transparency and high-cleanness, high, is mainly used in TP laminating, holds when laminating
Easily occur that when light mould release membrance or weight mould release membrance draw glue to cause product bad and fit, location is abnormal.
Chinese Patent Application No.: 201520791268.1, discloses a kind of OCA with anti-electromagnetic wave effect
Optical adhesive film, including the heavy mould release membrance set gradually from top to bottom, anti-electromagnetic wave height mucigel, layer of silica gel and
Middle mould release membrance, the upper surface of anti-electromagnetic wave height mucigel, lower surface respectively with weight the lower surface of mould release membrance, silicon
The upper surface laminating of glue-line, the upper surface laminating of the lower surface of layer of silica gel and middle mould release membrance.
Chinese Patent Application No.: 201420663188.3, discloses a kind of OCA optical film, refers in particular to
A kind of OCA optical film；The edge of OCA optical cement tablet weight release film layer is outwardly away from optical cement layer, described gently
Release film layer covers optical cement layer edge；The production technology of OCA optical film include just the most die-cut, go original gently from
Type film layer, cover light release film layer, secondary punch, cut-out operation, the heavy release film layer of OCA optical film
Edge is outwardly away from optical cement layer, and described light release film layer covers optical cement layer edge.
It is complicated that foregoing invention creates structure, light mould release membrance during laminating and weight mould release membrance Yi Fashengla glue, causes
Peeling effect is the best, and is susceptible to position abnormal problem when laminating.
Utility model content
The purpose of this utility model is, overcomes the drawbacks described above of prior art, it is provided that a kind of OCA optical cement.
For achieving the above object, the technical scheme that this utility model provides is as follows: a kind of OCA optical cement, bag
Include and be sequentially provided with light mould release membrance, optical adhesive film, weight mould release membrance, its described four L of heavy mould release membrance from top to bottom
A MARK point it is respectively equipped with on angle.
Wherein, light mould release membrance width is more than weight mould release membrance width 2 to 4mm, and light mould release membrance height is release with weight
Film height is equal.
Wherein, weight mould release membrance width is more than optical adhesive film width 3 to 5mm, and weight mould release membrance height is more than optics
Glue height 4 to 5mm.
Of the present utility model have the beneficial effect that by making man-hour weight mould release membrance size more than optical adhesive film chi adding
Very little, on weight mould release membrance, increase MARK location simultaneously indicate, separately light mould release membrance is strengthened simultaneously, and be more than
Weight mould release membrance, so may insure that optical adhesive film to be in all the time between light mould release membrance and weight mould release membrance and keeps preferably
Peeling effect, the release face of optical adhesive film edge and light mould release membrance and weight mould release membrance contacts all the time does not glue
Even, the MARK point on weight mould release membrance can precisely solve the problem that during TP laminating, location is abnormal.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of this utility model OCA optical cement；
Fig. 2 is the schematic side view of this utility model OCA optical cement.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment is further described with regard to the technical solution of the utility model.
As Figure 1-Figure 2, a kind of OCA optical cement described in the utility model, including the most successively
The weight mould release membrance 1 arranged, optical adhesive film 2, light mould release membrance 3, weight mould release membrance is respectively equipped with on 1 four L angles
MARK point 11, the 2nd MARK point 12, the 3rd MARK point 13, the 4th MARK point 14.
Further, light mould release membrance 3 width is more than weight mould release membrance 1 width 2 to 4mm, and light mould release membrance 3 is high
Spend the most equal with weight mould release membrance 1.
Further, weight mould release membrance 1 width is more than optical adhesive film 2 width 3 to 5mm, and weight mould release membrance 1 is high
Degree is more than optical adhesive film height 4 to 5mm.
Above, by add make man-hour weight mould release membrance 1 size more than optical adhesive film 2 size, simultaneously weight from
Increase MARK location on type film 1 to indicate, separately light mould release membrance 3 is strengthened simultaneously, and more than weight mould release membrance 1,
So may insure that optical adhesive film 2 is between light mould release membrance 3 and weight mould release membrance 1 holding preferably stripping all the time
From effect, optical adhesive film 2 edge contacts all the time with the release face of light mould release membrance 3 and weight mould release membrance 1 and does not occur
Adhesion, the MARK point on weight mould release membrance 1 can precisely solve the problem that during TP laminating, location is abnormal.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that, this area
For those of ordinary skill, on the premise of without departing from this utility model principle, moreover it is possible to make some modification
And improvement, also should be regarded as belonging to protection domain of the present utility model.
