Abstract
The utility model discloses a kind of back light module unit structure, the backlight module include chase, the backlight that is installed in chase and be installed on the right side of backlight according to lower and on stack reflector plate, light guide plate, optical diaphragm group and shading rubber belt successively, the backlight includes LED light bar, installation and the FPC for being electrically connected with LED light bar.The chase is in semi-surrounding structure in source ends outer wall, its bottom is provided with the step position for being used for clamping FPC, the utility model to chase by that will carry out structure design, FPC is placed in below LED light bar, the area of shading rubber belt covering blooming piece can effectively be reduced, increase the area of backlight module viewing area, improve the screen accounting of backlight module viewing area.
Description
Technical field
Backlight display technology field is the utility model is related to, more particularly, to a kind of back light module unit structure.
Background technology
Because liquid crystal display screen of mobile phone has many advantages, such as：Zero radiation, low power consuming, the small slim light and handy, frame stabilization of radiating
Do not flash；Liquid crystal display panel does not light in itself, so to form display device together with backlight module.If shielding is bad
Exposure can occur, contrast and the brightness of LCDs will be influenceed.In order to prevent the generation of light leakage phenomena, generally use hides
Optical cement band fixes liquid crystal display screen of mobile phone.Backlight sets gradually FPC and LED in light inputting end in prior art backlight module
Bar, shading rubber belt are attached to the light inputting end of blooming piece, the Back Word that shading rubber belt is surrounded on blooming piece in backlight module
Region in shape region constitutes the viewing area of backlight module, and with the continuous expansion of mobile phone screen size, PFC is placed in
Add the width of shading rubber belt above LED light bar, the area of shading rubber belt overlay area increases in backlight module, causes backlight
The screen accounting of module viewing area is relatively low.
The content of the invention
The utility model provides a kind of back light module unit structure, and to solve the problems, such as to mention in background technology, this practicality is new
Technical scheme is used by type：A kind of back light module unit structure, including chase, the backlight that is installed in chase and installation
On the right side of the backlight according to lower and on stack reflector plate, light guide plate, optical diaphragm group and the parallel screening for being attached at optics module successively
Optical cement band, the backlight include LED light bar, installation and the FPC for being electrically connected with LED light bar, and the chase outer wall is in semi-surrounding
Structure, bottom are provided with the step position for being used for clamping FPC.
Further, the FPC is pasted together by the first double faced adhesive tape and the light guide section bottom.
Further, the FPC is pasted together by the second double faced adhesive tape and the guide-lighting front edge of board.
Further, the shading rubber belt is strip adhesive tape；The width of the shading rubber belt is within 3mm.
Relative to prior art, the utility model ensures that shading rubber belt can be with by being in semi-surrounding structure in chase outer wall
Firm is pasted onto in optics module, while is less likely to occur to deform；FPC is pasted on LED light bar after setting boss on the inside of chase
Lower section, in the case where not changing shading performance and display effect, reduce the area of shading rubber belt covering optical diaphragm group, increase
The area of backlight module viewing area, and then improve the screen accounting of backlight module viewing area.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model back light module unit structure.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is further described in detail, should
Understanding, the case described herein that is preferable to carry out is merely to illustrate and explained the utility model, and without with limiting this practicality newly
Type.
Fig. 1 is that a kind of the utility model back light module unit structure cuts open schematic diagram, as shown in Figure 1, a kind of back light module unit structure,
Including chase 11, be installed in chase 11 according to lower and on stack reflector plate 12, light guide plate 13, optical diaphragm group 14 and shading successively
Adhesive tape 15, the light guide plate 13 include FPC16, installation and the LED light bar 17 for being electrically connected with FPC16, the shading in light inputting end
Adhesive tape 15 is pasted onto the top of optical diaphragm group 14, and shading rubber belt 15 is strip adhesive tape, and width is within 3mm.
Wherein, chase 11 is pasted on below FPC16 by the first double faced adhesive tape 18, and light guide plate 13 is viscous by the second double faced adhesive tape 19
It is affixed on below FPC16.
The backlight module of this preferred embodiment is by making the outer wall of chase 11 be in semi-surrounding structure, and shading rubber belt 15 is more easily
Chase 11 and the top of optical diaphragm group 14 are pasted on, chase 11 is provided with the step position 111 for being used for clamping FPC16, and such FPC16 can
The lower section of LED light bar 17 is pasted onto, the width of shading rubber belt 15 is reduced, while the area of the overlay area of shading rubber belt 15 reduces
Add backlight module viewing area area.
During work, LED light bar 17 launches light, and the bottom of light guide plate 13, light guide plate 13 are injected from the incidence surface of light guide plate 13
Side light source is converted into area source to send, optical diaphragm group 14 is handled the light that the light-emitting area of light guide plate 13 projects, and is improved
The positive brightness of backlight module.
Meanwhile the horizontal shading rubber belt 15 for being pasted on the top of optical diaphragm group 14, the surrounding of optical diaphragm group 14 is spilt
Light blocks, and prevents screen from occurring bright border hidden danger because of light leak.
The utility model has carried out detailed explanation by preferred embodiment.However, by studying carefully above,
Apparent to change and increase and those of ordinary skill in the art to each embodiment.The utility model passes through upper
Embodiment is stated to illustrate embodiment and structure of the present utility model, profit is not limited to above-mentioned embodiment, all uses and sheet
The similar structure of utility model realizes all modes of the utility model purpose, within the scope of protection of the utility model.
