Abstract
The utility model discloses a kind of backlight assembly structure, which includes shading glue, located at the upper brightening piece of shading glue bottom, located at the lower diffusion sheet of upper brightening piece bottom, the bottom connection light guide plate of lower diffusion sheet, light guide plate arrange LED light source in side, the lower section connection glue frame of light guide plate, glue frame bottom is provided with adhesive layer, and the bottom of adhesive layer has reflector plate, and the lower diffusion sheet located at LED light source side is provided with 3 10 sections of black belts.This utility model can be avoided because black belt is long, cause lower diffusion sheet because black belt bounces back the problem of buckling deformation, it is to avoid the buckling deformation of lower diffusion sheet, so as to reducing scrapping for product.
Description
Technical field
This utility model is related to a kind of mobile phone backlight modular construction.
Background technology
As shown in Figures 1 and 2, be existing mobile phone screen back light module unit structure, which includes shading glue 1 ', located at shading glue
The upper brightening piece 2 ' of 1 ' bottom, located at the lower diffusion sheet 3 ' of 2 ' bottom of upper brightening piece, the bottom connection light guide plate of lower diffusion sheet 3 '
4 ', light guide plate 4 ' arranges LED light source 5 ' in side, and the lower section of light guide plate 4 ' connects glue frame 6 ', and 6 ' bottom of glue frame is provided with adhesive layer
7 ', the bottom of adhesive layer 7 ' has a reflector plate 8 ', shading glue 1 ' be attached in glue frame 6 ' it is fixed, and by upper brightening piece 2 ', lower diffusion
Piece 3 ', light guide plate 4 ' and LED light source 5 ' are fixed.In existing backlight assembly structure, as lamp eye is also easy to produce at light source, it is to improve light
Effect is learned, a black belt 9 ' can be pasted on the lower diffusion sheet of light source direction.Black belt 9 ' before diffusion sheet is sticked, meeting
Pasted after black belt 9 ' is stretched again, because the black belt 9 ' of required patch on lower diffusion sheet 3 ' is elongated shape and black belt
9 ' belong to expansion performance material so that black belt 9 ' is understood after being straightened because of material behavior retraction, so pasted black
Under part after adhesive tape diffusion sheet 3 ' can because black belt 9 ' retraction and buckling deformation, cause backlight assembly to be scrapped.
In view of this, the design people for do not attain in present backlight assembly structure design improve caused by institute many disappearances with
It is inconvenient deeply to conceive, and actively research improvement has a fling at and develops and design this utility model.
Utility model content
The purpose of this utility model is to provide a kind of backlight assembly structure for improving lower diffusion sheet buckling deformation, is reduced
Product is scrapped.
In order to reach above-mentioned purpose, solution of the present utility model is：
A kind of backlight assembly structure, which includes shading glue, located at the upper brightening piece of shading glue bottom, located at upper brightening piece bottom
The lower diffusion sheet in portion, the bottom connection light guide plate of lower diffusion sheet, light guide plate arrange LED light source in side, connect below light guide plate
Glue frame is connect, glue frame bottom is provided with adhesive layer, and the bottom of adhesive layer has reflector plate, and shading glue is attached in glue frame and fixes, and will be upper
Brightening piece, lower diffusion sheet, light guide plate and LED light source are fixed, and the lower diffusion sheet located at LED light source side is provided with 3-10 section black
Adhesive tape.
After said structure, this utility model backlight assembly is, in assembling, black belt to be pasted lower diffusion sheet
Afterwards, location for paste is cut off, black belt cut-out is become into some sections, can avoid, because black belt is long, causing lower diffusion
Piece problem of buckling deformation because black belt bounces back, it is to avoid the buckling deformation of lower diffusion sheet, so as to reducing scrapping for product.

Fig. 2 is the side sectional view of existing mobile phone backlight module.
Three-dimensional exploded views of the Fig. 3 for this utility model backlight module.
Sectional views of the Fig. 4 for this utility model backlight module.
Specific embodiment
In order to the technical solution of the utility model is explained further, this utility model is entered below by specific embodiment
Row is elaborated.
As described in Fig. 3 and Fig. 4, this utility model discloses a kind of backlight assembly structure, and which includes shading glue 1, located at screening
The upper brightening piece 2 of 1 bottom of optical cement, located at the lower diffusion sheet 3 of 2 bottom of upper brightening piece, the bottom of lower diffusion sheet 3 connects light guide plate 4,
Light guide plate 4 arranges LED light source 5 in side, and the lower section of light guide plate 4 connects glue frame 6, and 6 bottom of glue frame is provided with adhesive layer 7, adhesive layer
7 bottom has reflector plate 8, and the lower diffusion sheet of 5 side of LED light source is provided with black belt 9, when backlight assembly is assembled,
Black belt 9 is pasted after lower diffusion sheet 3, according to the length and expansion performance of black belt 9, ground at 3-10 at paste, is cut off
Side.
This utility model backlight assembly is, in assembling, black belt 9 to be pasted after lower diffusion sheet 3, location for paste is entered
The cut-out of black belt 9 is become some sections, can avoid, because black belt 9 is long, causing lower diffusion sheet 3 because of black glue by row cut-out
The problem of buckling deformation with 9 retractions, it is to avoid the buckling deformation of lower diffusion sheet 3, so as to reducing scrapping for product.
Above-described embodiment and schema non-limiting product form of the present utility model and style, any art
Appropriate change or modification that those of ordinary skill is done to which, all should be regarded as without departing from patent category of the present utility model.
