Abstract
The utility model discloses a backlight unit's optics diaphragm leak protection photo structure, including the board that is shaded, the upside of board in a poor light is equipped with the reflector plate, the board setting of being shaded is hugged closely to the reflector plate, and its middle part that is located the board that is shaded, the both sides of reflector plate upper surface are equipped with the sticky tape, the sticky tape sets up along the edge of reflector plate, and the sticky tape puts on the shelf and be equipped with the light guide plate, form the clearance between reflector plate and the light guide plate. The utility model discloses in, set up the sticky tape through the both sides at the reflector plate upper surface, great reduction because the LCD module frame is crossed narrowly and the risk of light leak with great visual angle that cause, improved the quality of product, in addition, sticky tape through setting up has increaseed the clearance between reflector plate and the light guide plate, and the yield and the work efficiency of effectual improvement product also have great promotion simultaneously in the aspect of the normality of reality is bad.
Description
Technical field
This utility model relates to back light model setting technology field, particularly relates to the blooming piece anti-light leakage structure of a kind of backlight module.
Background technology
Backlight module is one of key part and component of panel of LCD.Function is well-off brightness and is evenly distributed
Light source so that it is can normal show image.
Along with liquid crystal module development ultra-narrow frame and lightening, the frame synchronizing backlight is the most more and more narrow；For backlight module
Blooming piece (reflector plate), too narrow due to frame after assembling, problem that the big visual angle light leak of both sides often occur, not only improves
The difficulty assembled, the also strong influence quality of product.Additionally, between traditional backlight module reflector plate and light guide plate
Gap is too small, and this has impact in various degree to yield rate and the work efficiency of final products.
To this end, it is proposed that the blooming piece anti-light leakage structure of a kind of backlight module solves the problems referred to above.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the blooming of a kind of backlight module proposed
Sheet anti-light leakage structure.
To achieve these goals, this utility model adopts the technical scheme that
The blooming piece anti-light leakage structure of a kind of backlight module, including backlight, the upside of described backlight is provided with reflector plate, institute
Stating reflector plate and be close to backlight setting, and it is positioned at the middle part of backlight, the both sides of described reflector plate upper surface are provided with adhesive tape, institute
State the adhesive tape edge setting along reflector plate, and the added light guide plate that is provided with of adhesive tape, between described reflector plate and light guide plate, form gap.
Preferably, the thickness of described reflector plate is less than the thickness of backlight.
Preferably, the side of described light guide plate is provided with light source.
Preferably, described light source is LED.
Preferably, described adhesive tape uses Kapton Tape.
Compared with prior art, the beneficial effects of the utility model are: by arranging adhesive tape in the both sides of reflector plate upper surface, greatly
Big reduces big visual angle light leak risk that is narrow due to liquid crystal module frame and that cause, improves the quality of product；By arranging
Adhesive tape, increase the gap between reflector plate and light guide plate, effectively raise yield rate and the work efficiency of product, with
Time also have a distinct increment at the actual bad aspect of normality；Additionally, this utility model compact conformation, production technology is simple, can have
The cost controlling to produce of effect, and beneficially anti-light leakage structure is universal.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the blooming piece anti-light leakage structure of a kind of backlight module that the utility model proposes；
Fig. 2 is the side structure schematic diagram of the blooming piece anti-light leakage structure of a kind of backlight module that the utility model proposes.
In figure: 1 backlight, 2 reflector plates, 3 adhesive tapes, 4 light guide plates, 5 gaps.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole realities
Execute example.Based on the embodiment in this utility model, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
With reference to Fig. 1-2, the blooming piece anti-light leakage structure of a kind of backlight module, including backlight 1, the upside of backlight 1 sets
Having reflector plate 2, the light that reflector plate 2 is given out by light source for reflection, the thickness of reflector plate 2 is less than the thickness of backlight 1
Degree, reflector plate 2 is close to backlight 1 and is arranged, and reflector plate 2 is positioned at the middle part of backlight 1, is beneficial to reduce the whole of backlight module
Body thickness, the both sides of reflector plate 2 upper surface are provided with adhesive tape 3, and adhesive tape 3 can use Kapton Tape, and adhesive tape 3 is along reflector plate
The edge of 2 is arranged, and for solving big visual angle leakage problem that is narrow due to liquid crystal module frame and that cause, adhesive tape 3 is added to be provided with
Light guide plate 4, is used for controlling scattering of light direction, and the line source of light source is converted into uniform area light source, and the side of light guide plate 4 is provided with
Light source, light source can use LED, owing to adhesive tape 3 has certain width and thickness so that light guide plate 4 and reflector plate 2
Between space out, the actual bad aspect of normality also has a distinct increment.
In this utility model, by arranging adhesive tape 3 in the both sides of reflector plate 2 upper surface, to reduce due to liquid crystal module frame mistake
Narrow and the big visual angle light leak risk that causes；Additionally, utilize the adhesive tape 3 arranged, strengthen shape between reflector plate 2 and light guide plate 4
Become gap 5, thus improve yield rate and the work efficiency of product.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model does not limit to
In this, any those familiar with the art is in the technical scope that this utility model discloses, according to of the present utility model
Technical scheme and utility model thereof conceive equivalent or change in addition, all should contain within protection domain of the present utility model.
