Description
Technical field
The present invention relates to back light source technique fields, and in particular to a kind of screening with side clad structure for backlight
The preparation method of optical cement.
Background technique
A kind of light source of the backlight as the behind liquid crystal display (LCD), its illumination effect will directly influence liquid crystal
Display module (LCM) visual effect.Main light with the high speed development of the electronic equipments such as touch-screen mobile phone, as liquid crystal display
Source, demand is big, and earth-shaking change consequently also has occurred in the production scale of backlight.
In existing backlight production, to prevent backlight light leakage, it will usually which using includes pasting in the edge of backlight
The measure of shading glue.And in existing backlight production process, there is narrower frame due to requiring backlight, shading glue
Seal ring thickness cannot be excessive, and either manually or mechanically direct rubberizing is not easy to operate, is easy to cause the damage of backlight, or leads to rubberizing
Illumination effect that is irregular, unsightly influencing backlight.
Simultaneously as requirement of the existing backlight to narrow frame is higher and higher, cause each layer structure of backlight direct
Adhesive glue position is smaller and smaller, is unfavorable for the integrally-built stabilization of backlight, is easy to appear situations such as loose.Therefore, increasing back
While the shaded effect of light source carries out patch shading glue, it is also necessary to consider how to carry out reinforcing stabilization to the structure of backlight, make
Backlight can reach stable effect while meeting narrow frame.
Summary of the invention
The purpose of the present invention in view of the deficiencies of the prior art, provide it is a kind of for backlight have side clad structure
Shading glue preparation method.Method of the invention can prepare the disposable stickup shading glue suitable for narrow frame backlight,
Directly the edge of the shading glue of preparation alignment backlight is pasted in use process, settles at one go, is cut without scene, is avoided pair
The damage or rubberizing of backlight are irregular；Meanwhile the shading glue of this method preparation also has the packet that backlight side is coated and fixed
Structure is covered, clad structure coats the side of narrow side backlight when pasting shading glue, keeps narrow side back light source structure firm,
It is not susceptible to phenomena such as loose.
The purpose of the present invention is achieved through the following technical solutions.
A kind of preparation method of the shading glue with side clad structure for backlight, the preparation method will first attach
In carrier release paper monolith shading glue and black glue item cut after obtain the clad structure with cladding backlight side
After shading glue edge contour, then carrier release paper is carried out to cut out the release paper block with handle is drawn, be completed to for backlight
The preparation of shading glue with side clad structure.
Specifically comprise the following steps:

Preferably, the size of first release paper, the second release paper and third release paper is identical, and it is black to cover patch
Rectangle entirety shading blob of viscose after adhesive tape.
Shading glue has viscosity, and carrier of the release paper as shading glue is avoided that shading glue is pasted with mechanical, is preparing
The fluency of preparation process is protected and ensure that shading glue in the process；Meanwhile in the finished product for completing preparation, shading
Glue is still used as carrier to continue to protect shading glue and shifted, until shading glue is used and is fitted on backlight.
Preferably, in step (4), the edge contour corresponding to backlight shape is corresponding to backlight shape edges
Frame shape profile.For rectangle entirety shading blob of viscose during cutting, middle position part is cut removal, remaining edge frame shape
Outline portion, the frame shape profile are closed frame shape profile, and corresponding with the edge shape of backlight.
It is furthermore preferred that the border width of the frame shape profile is 0.70mm ~ 0.86mm.
Preferably, in step (4), the clad structure of the corresponding cladding backlight side is that black glue item extends outward square
The remaining black glue item still retained after the part of shape entirety shading blob of viscose side edge is cut.Clad structure is according to backlight side
Encapsulated cut, according only to the portion for extending outward rectangle entirety shading blob of viscose side edge needed to black glue item
Divide and is cut.
Preferably, in step (4), the cladding backlight side includes full cladding or part coats backlight side, and
The FPC for reserving backlight draws port.
The position that FPC draws port is as needed, and bottom end or the two side ends of backlight are accordingly arranged in, need when encapsulated
It reserves FPC and draws port.
It is furthermore preferred that the cladding backlight side includes extending and coating to the shell back of backlight in step (4)
Face, or extend and coat to the end face of backlight, and it is not extend to the back side of shell of backlight.
Preferably, in step (5), the overturning is that front and back sides are overturn, and rotate 180 °.
Preferably, in step (6), the flexible circuit board (FPC) that the position for drawing handle corresponds to backlight draws port
Position.It draws the structure remained after being cut for the first release paper, the rectangle release paper block portion point that the first release paper remains after cutting
The frame shape profile after rectangle entirety shading blob of viscose is cut is covered, the inside including covering frame shape profile surrounds blank parts.
Compared with prior art, the invention has the advantages that and the utility model has the advantages that
