Description
Technical field
The utility model relates to technical field of liquid crystal display more particularly to a kind of light leakage backlight modules.
Background technique
Backlight module is one of the key part and component of panel of LCD, and function is well-off brightness and distribution
Uniform light source can normally show that image, so-called backlight are a kind of light source positioned at liquid crystal display behind, its hair
Light effect will directly influence LCD MODULE visual effect, and liquid crystal itself does not shine, it shows figure or character is it
To light modulation as a result, simultaneously, after light guide plate attaches diffusion barrier and reflectance coating, surrounding is needed to attach shading rubber belt for hiding
The problem of keeping off product surrounding light leakage, attaching efficiency is low, and cost of labor increases.
Currently, cell phone back light source generallys use plastic cement outline border or is integrally used as outline border using glue modeling and iron frame, glued on outline border
A photomask is pasted, on one side for pasting fixed optical film material, in addition one side pastes liquid crystal display, is bonded and touches on display screen
Screen or glass cover-plate, touch screen or glass cover-plate are pasted on phone housing.If it is intended to mobile phone shape is accomplished minimum simultaneously
Maximum is accomplished in viewing area, mobile phone shell must be accomplished it is most narrow, while outside touch screen and display screen, the non-luminous region of backlight
Need to accomplish it is most narrow, and backlight outside do it is too narrow be easy to produce leakage problem, thus restrict from viewing area to mobile phone frame
Do it is narrow, meanwhile, after light guide plate attaches diffusion barrier and reflectance coating, surrounding is needed to attach shading rubber belt for blocking product surrounding
The problem of light leakage, attaching efficiency is low, and cost of labor increases.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of light leakage backlight proposed
Mould group.To achieve the goals above, the utility model adopts the technical scheme that a kind of backlight anti-light leakage structure, special
Sign is, including iron frame, bright enhancement film, diffusion barrier, light guide plate, edge-wrapping adhesive band and LED luminescence component, which is characterized in that described
Iron frame upwardly extends, bottom surface, side and top surface formed an accommodating space, the diffusion barrier, LED luminescence component, light guide plate by
It is successively set under in the accommodating space that the iron frame is formed, the edge-wrapping adhesive band includes the bottom for coating the iron frame bottom surface
The top bound edge of bound edge, the side bound edge of the cladding iron frame side and the cladding iron frame bottom surface, the bright enhancement film and the iron frame
Between from top to bottom attach the isolation film of anti-tilting and for light-blocking black PET；Wherein, the iron frame and the bright enhancement film are logical
Shading glue close adhesion is crossed, the bright enhancement film and the iron frame top surface are located at same level.
As above-mentioned technical proposal to further describe: the isolation film single side has glue or two-sided no glue.
As above-mentioned technical proposal to further describe: the isolation film is no glue in the covering region the black PET.
It is as above-mentioned technical proposal to further describe: the isolation film concordantly with the iron frame top surface.
As above-mentioned technical proposal to further describe: the black PET width is less than the width of the isolation film.
The beneficial effects of the utility model are: compared with prior art, the backlight bound edge leakproof that this practical information provides
Photo structure adds isolation film above light-blocking black PET, will be close to source ends black PET and iron frame top surface, make diffusion barrier with
Shading glue, which separates, to be come, so that the interlayer structure of black PET and shading glue composition iron frame top surface designs, solves ultra-thin, narrow frame
The problem of for backlight module in assembling, the bounce of edge-wrapping adhesive band drives diffusion barrier offset, forms backlight socket hot spot, mentions significantly
The reliability that high ultra-thin, narrow frame back backlight module product yield and product use.
Detailed description of the invention
Fig. 1 is the utility model source ends structural schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on this it is practical in embodiment, those of ordinary skill in the art are without creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to shown in Fig. 1, a kind of backlight anti-light leakage structure of the utility model comprising iron frame 101, bright enhancement film
102, diffusion barrier 103, light guide plate 104, edge-wrapping adhesive band 105 and LED luminescence component, which is characterized in that the iron frame 101 is upwards
Extend, forms an accommodating space in bottom surface, side and top surface, the diffusion barrier 103, LED luminescence component, light guide plate 104 are by upper
It is successively set under in the accommodating space that the iron frame 101 is formed, the edge-wrapping adhesive band 105 includes coating the iron frame 101
The top bound edge of the bottom bound edge of bottom surface, the side bound edge of cladding 101 side of iron frame and cladding 101 bottom surface of iron frame, the increasing
The isolation film 106 of anti-tilting is from top to bottom attached between light film 102 and the iron frame 101 and for light-blocking black PET107；
Wherein, the iron frame 101 and the bright enhancement film 102 pass through shading glue close adhesion, the bright enhancement film 102 and the iron frame 101
Top surface is located at same level.
In the present embodiment, the reflectance coating is covered on the lower surface of the light guide plate 104, the surface setting of the reflectance coating
Bright enhancement film 102, and shading glue is set in the source ends of the iron frame 101 and tail portion, never make reflectance coating source ends and
Tail portion shading, intermediate light out, guarantee narrow frame backlight product goes out light quality.
Preferably, 106 single side of isolation film has glue or two-sided no glue.
Preferably, the isolation film 106 is no glue in the covering side the black PET107.
Preferably, the isolation film 106 concordantly with 101 top surface of iron frame.
Preferably, the black PET107 width is less than the width of the isolation film 106.
The structural principle of the utility model is summarized as follows:
In one separation layer of shading glue envisaged underneath.The separation layer, which can be single side, glue or two-sided no glue.It is black covering
The side color PET must be without glue, the pull-up shading glue when binding structure reflexed, shading glue simultaneously can related pull-up separation layer, because every
Absciss layer and black PET will not take up black PET, form backlight socket hot spot without adhesive relationship, to solve bound edge pull-up diffusion
The phenomenon that film.Using this it is practical separation layer is set between shading glue and black PET, on the one hand need not artificial pad pasting, it can be achieved that
Full-automatic or semiautomatic working, reduces material amounts, reduces costs and material utilization amount；On the other hand, separation layer is primary
Property positioning paste, avoid pad pasting positional shift caused by traditional-handwork pad pasting, improve product yield.
The above is only the preferred embodiment of the utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification that structure, feature and principle is done, is included in the scope of the utility model patent application.
