Abstract
The utility model discloses a kind of structures for preventing reflection diaphragm from shifting, it include: glue frame, reflection diaphragm and light guide plate, the light guide plate is arranged in the glue frame, ear is convexly equipped on the two sidewalls of the reflection diaphragm, the ear is concaved with card far from the reflection diaphragm side and sets opening, it offers limit opening corresponding with the ear on the glue frame inner sidewall, is convexly equipped in the limit opening and sets the corresponding boss of opening with the card；Restitope film is additionally provided at the limit opening, the top of the light guide plate is arranged in the restitope film, and the restitope film is arranged in parallel with the light guide plate.Technical solutions of the utility model are intended to reduce the displacement risk of reflection diaphragm, reduce because reflection diaphragm displacement it is bad caused by repair rate, it is energy saving to save cost of labor and Material Cost.
Description
Technical field
The utility model relates to liquid crystal module group backlight structure technical fields, in particular to a kind of to prevent reflection diaphragm from shifting
Structure.
Background technique
Existing LCM liquid crystal module group backlight structure, membrane material and adhesive frame structure is mating is fixed by ear location, diaphragm directly pastes
In on backlight guide plate, mould group terminal use or transportational process in because mould group is shaken, easily cause membrane material 3 move up and down or
There is reflection diaphragm to enter in the gap between glue frame and light guide plate, forms reflection diaphragm displacement, cause bad.Due to diaphragm
What is shifted is bad, and subsequent reprocess will cause scrapping and artificial waste for lot of materials to complete machine dismounting.
Therefore, it is necessary to propose a kind of new solution.
Utility model content
The main purpose of the utility model is to propose a kind of structure for preventing reflection diaphragm from shifting, it is intended to reduce reflection diaphragm
Displacement risk, reduce because repair rate is saved to save cost of labor and Material Cost caused by reflection diaphragm displacement is bad
The energy.
To achieve the above object, the utility model proposes it is a kind of prevent reflection diaphragm shift structure, comprising: glue frame,
Reflection diaphragm and light guide plate, the light guide plate are arranged in the glue frame, are convexly equipped with ear on the two sidewalls of the reflection diaphragm,
The ear is concaved with card far from the reflection diaphragm side and sets opening, offers on the glue frame inner sidewall and the ear
Piece corresponding limit opening is convexly equipped in the limit opening and sets the corresponding boss of opening with the card, the boss and
The card sets opening and is adapted, and the boss is inlayed setting and set in opening in the card；It is additionally provided at the limit opening
The top of the light guide plate is arranged in restitope film, the restitope film, and the restitope film is parallel with the light guide plate sets
It sets.
Preferably, restitope film is provided on other side walls of the glue frame.
Compared with prior art, the utility model is by traditional adhesive frame structure and the matched conventional design method of reflection diaphragm,
After the card of boss and reflection diaphragm in the limit opening of increase glue frame sets opening and restitope film, employee is in assembling membrane material process
In with being assembled without difference originally, do not need training to change processing procedure, in cost of material, cost of labor does not all increase, passes through
The structure can be improved module reliability and reduce since membrane material shifts bring fraction defective.By novel glue frame membrane material structure, making
Make, reliability improves in use and transportational process.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is this practical new structural schematic diagram；
Fig. 2 is the enlarged diagram in Fig. 1 at A；
Fig. 3 is enlarged diagram of the glue frame at A；
Fig. 4 is enlarged diagram of the reflection diaphragm at A；
Fig. 5 is section schematic diagram local in the utility model；
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
A kind of structure for preventing reflection diaphragm from shifting that the present embodiment proposes, as shown in Figures 1 to 5 comprising: glue frame
100, reflection diaphragm 200 and light guide plate 300, light guide plate 300 are arranged in glue frame 100, projection on the two sidewalls of reflection diaphragm 200
There is ear 210, ear 210 is concaved with card far from 200 side of reflection diaphragm and sets opening 211, opens up on 100 inner sidewall of glue frame
There is limit opening 110 corresponding with ear 210, is convexly equipped in limit opening 110 and sets 211 corresponding boss of opening with card
111, boss 111 sets opening 211 with card and is adapted, and boss 111 is inlayed setting and set in opening 211 in card；At limit opening 110
It is additionally provided with restitope film 112, the top of light guide plate 300, and restitope film 112 and light guide plate 300 is arranged in restitope film 112
It is arranged in parallel.
Glue frame 100 and reflection diaphragm 200 are fixed by the structure of ear 210 and limit opening 110, after assembling,
After the strenuous exercise in use process or in transportational process, easily cause membrane material displacement to cause end product to show white edge
Etc. bad, into after excessively novel 210,100 ear of glue frame improvement, as shown in figure 3, glue frame 100 is increased boss 111 and restitope glue
Piece 112 designs, and increases by 100 boss 111 of glue frame and protrudes into increase contact area in reflection diaphragm 200, bottom increases restitope film 112
Reflection diaphragm 200 is held, reflection diaphragm 200 is prevented to be moved between glue frame 100 and light guide plate 300.It is being used and is being transported
After shaking caused by the process, reflection diaphragm 200 and 100 combination of glue frame are even closer than before,
Further, restitope film 112 is provided on other side walls of glue frame 100.
Traditional 100 structure of glue frame and the matched conventional design method of reflection diaphragm 200 are increased glue frame by the utility model
After the card of boss 111 and reflection diaphragm 200 in 100 limit opening 110 sets opening 211 and restitope film 112, employee is in group
With being assembled without difference originally during dress membrane material, training is not needed to change processing procedure, in cost of material, cost of labor does not all have
Increase, module reliability can be improved with this configuration to be reduced since membrane material shifts bring fraction defective.By novel 100 film of glue frame
Material structure, reliability improves in production, use and transportational process.
The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
