Description
Technical field
The utility model is related to liquid crystal display fields, and in particular to a kind of backlight shading glue.
Background technology
LCD display modules generally need to use backlight backlights, and backlight is needed with LCD bondings using shading glue 200,
Usually there are two types of materials, two-sided black, are commonly called as black glue and colourless one side is black, be commonly called as black and white glue.
100 main problem of black and white glue is light leakage, but because being on one side white adhesive layer 300, helpful to luminance raising.It is black
Glue-line can solve surrounding light leakage bright border, but because black glue absorption effects can sacrifice 5% or so LCD display brightness.Such as Fig. 1 institutes
Show, black and white glue, which surpasses the white pet layer in inside, largely reflection lights to be recycled, and the light after wherein most reflection is small from edge
Angle projects, and (recycling light and vertical direction angle are small) can cause human viewable edge partially bright.
Invention content
The technical problem to be solved by the utility model is to provide a kind of backlight shading glues, can be divided, carried with recoverer
High LCD entirety display brightness, compared with traditional black and white glue, the problems such as effectively mitigating shinny surrounding, bad light-leaking.
The utility model is achieved through the following technical solutions：A kind of backlight shading glue, including LCD glass, glue
Frame, shading glue, reflector plate and backlight light-guiding and film layers, reflector plate are installed on glue frame bottom, backlight light-guiding and film layers of peace
Upper end loaded on reflector plate, LCD glass are installed on the top of glue frame by shading glue, the shading glue include the first black glue layer,
Second black glue layer and white adhesive layer, the upper end of the second black glue layer are provided with one layer of adhesive linkage, and upper end is connected by adhesive linkage
LCD glass.
As preferred technical solution, the first black glue layer is put in linear type with white adhesive layer and is set to the second black glue
The overall length of the lower end of layer, the first black glue layer and white adhesive layer is equal to the length of the second black glue layer.
As preferred technical solution, backlight side is the first black glue layer close to 50% width of visible side inwardly, close to non-visual
50% width of side is white adhesive layer.
The beneficial effects of the utility model are：The shading glue of the utility model can be divided with recoverer, improved LCD and integrally shown
Show brightness, compared with traditional black and white glue, the problems such as effectively mitigating shinny surrounding, bad light-leaking.
Description of the drawings
It 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, it can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure diagram of the prior art；
Fig. 2 is the structure diagram of the shading glue of the utility model；
Fig. 3 is the overall structure diagram of the utility model.
Specific embodiment
All features or disclosed all methods disclosed in this specification or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figures 2 and 3, including LCD glass 1, glue frame 7, shading glue, reflector plate 6 and backlight light-guiding and film layers
5, reflector plate 6 is installed on 7 bottom of glue frame, and backlight light-guiding and film layers 5 are installed on the upper end of reflector plate 6, and LCD glass 1 passes through screening
Optical cement is installed on the top of glue frame 7, and shading glue includes the first black glue layer 4, the second black glue layer 2 and white adhesive layer 3, the second black glue layer
2 upper end is provided with one layer of adhesive linkage, and the LCD glass 1 of upper end is connected by adhesive linkage 8.
First black glue layer 4 puts the lower end for being set to the second black glue layer, the first black glue layer 4 with white adhesive layer 3 in linear type
It is equal to the length of the second black glue layer 2 with the overall length of white adhesive layer 3.Backlight side is the first black glue layer close to 50% width of visible side inwardly,
It is white adhesive layer close to non-50% width of visible side.It is attached using such shading glue, both can guarantee that light was recycled while can be taken into account and kept away
It is seriously bad to exempt from surrounding light leakage.As shown in figure 3,50% black glue width of inside is avoided that the light recycling reflection of low-angle, human eye exists
Low-angle direction is less to observe the light recycled by shading glue, it is not easy to discover surrounding light leakage, 50% white glue part of inside can
To recycle the utilization of the light reflection of wide-angle, the light radiation of wide-angle is wide, it is not easy to concentrate on shading glue edge cause it is shinny.
The beneficial effects of the utility model are：The shading glue of the utility model can be divided with recoverer, improved LCD and integrally shown
Show brightness, compared with traditional black and white glue, the problems such as effectively mitigating shinny surrounding, bad light-leaking.
The above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
