Description
Technical field
The present embodiments relate to field of liquid crystal, more particularly to a kind of liquid crystal display module structure part and its assembling side
Method.
Background technology
At present, there is the trend developed to ultra-thin and large scale direction in LCD TV field.In the market releases nothing extensively
The characteristics of frame LCD TV, this Rimless LCD TV, is to eliminate traditional metal or plastic cement frame design, and takes
The problem of side frame structure member disappeared brings maximum is exactly the deficiency of LCD TV bulk strength.It is ultra-thin at present to solve the problem
The scheme that LCD TV improves intensity has two kinds：1st, MS light guide plates are changed to glass light guide plate, improve intensity；2nd, in scheme 1
On the basis of, glass light guide plate and backboard are fitted entirely, intensity is further improved.
Such scheme 2 is in particular：As shown in figure 1, on reflector plate 2 layer glue coating 4, for stationary backplate 1
With light guide plate 3.If this mode is used in large-sized liquid crystal module of 55 cun and the above, the area of glue application is led greatly
The amount of applying is more, and at present glue technique for fixing than traditional packaging technology in cost it is high 4~5 times.Further, since structural member is deposited
In certain flatness warpage, also result in and occur bubble after glue is attached, influence optics taste.
Therefore, the drawbacks of above-mentioned prior art is maximum is exactly cost height and yield caused by full assembly difficulty in process
It is low, so as to result in the high enterprise of current ultra-thin television price.
The content of the invention
In view of this, the purpose of the embodiment of the present invention is to propose a kind of liquid crystal display module structure part and its assemble method, purport
Solving how to reduce glue quantity, be avoided that aeration optics is sampled again, while intensity requirement can also be met
Problem.
In order to solve the above technical problems, the embodiment of the present invention proposes following technical scheme：
In a first aspect, a kind of liquid crystal display module structure part, it includes backboard, reflector plate, light guide plate, center, in the backboard
On be sequentially placed the reflector plate and the light guide plate, the center is placed with the edge of the backboard and the back of the body
The upper surface of plate, it is characterised in that：Inclined-plane is formed with the edge relative with the center of the light guide plate；In described
The corner that two faces relative with the light guide plate with the backboard of frame are formed is removed to form removal face for cambered surface；
Binding material is marked with the space being formed between the edge on the inclined-plane and the cambered surface removal face.
Optionally, the angle beta formed between the lower surface of the inclined-plane and the light guide plate is 30 °~45 °.
Optionally, the thickness A of the part on the edge Shang Fei inclined-plane relative with the center of the light guide plate is gross thickness
Substantially half.
Optionally, the removal face is cambered surface of the center of circle in the backboard direction..
Optionally, excessive glue groove is provided with the madial wall relative with the backboard of the center, the excessive glue groove is used to prevent
Only binding material overflows between the center and the backboard.
Optionally, the excessive glue groove is triangle or square.
Optionally, kept to the side between the light guide plate and the reflector plate edge position attach liquidproof infiltration material.
Optionally, sealing processing is carried out in the edge of the light guide plate and the reflector plate.
Optionally, the binding material is glue.
Second aspect, the assemble method of the liquid crystal display module structure part described in first aspect, it comprises the following steps：
(1), the reflector plate and the light guide plate are pre-fixed on the backboard successively, and institute is pre-fixed using tool
State center；
(2) binding material, is injected in the space being formed between the edge on the inclined-plane and the removal face.
Content can be seen that a kind of liquid crystal display module structure part provided in an embodiment of the present invention and its assembling side from above
Method, by using new binding material coating method, cancels the upper and lower surface binding material of reflector plate.It is by light guide plate and aluminium
The relative edge difference beveling of frame and removal face, so as to create gap between both and increase in light guide plate and aluminium
Frame and the contact area of binding material injected later are to improve fixing intensity；After structure assembling is finished one in the gap
Secondary property injects binding material, so that backboard, light guide plate and aluminium center be one-time fixed.So, application frequency, drop had both been reduced
Low binding material consumption, solves the problem of aeration optics is sampled, and also meet intensity requirement again.
