Abstract
The open a kind of backlight module of this utility model, including FPC, light guide plate, light source, reflector plate (1) and be attached to the glue frame (2) on reflector plate (1), described FPC(4), light guide plate and light source (5) be placed among described glue frame (2), described glue frame (2) inside bottom has a groove, glue (3) is put in a groove by dispensing technology, it is achieved the attaching between glue frame (2) and reflection (1) when attaching reflector plate (1) with glue frame (2).This utility model connects reflector plate and glue frame by dispensing technology, can effectively avoid employing double faced adhesive tape to attach high cost and the high light leak risk that reflector plate is brought with glue frame, can effectively reduce the thickness of backlight module simultaneously.
Description
Technical field
This utility model relates to back light model setting technology field, especially relates to a kind of backlight module.
Background technology
In existing backlight module, connect at attaching and generally use double faced adhesive tape to connect, such as transparent double face glue or black and white double faced adhesive tape, owing to it there will be, double faced adhesive tape cuts that excessive glue is bad, viscosity is not enough and reliability floats phenomenon, backlight will be caused to have the risk of light leak, and additionally light guide plate front end wedge structure makes light guide plate joint face and glue frame joint face can not aggravate the probability of happening of this phenomenon in sustained height plane.
Summary of the invention
This utility model aims to provide one can effectively attach connection, it is to avoid backlight light leak, improves the connected mode of optical quality.
For achieving the above object, this practicality newly be the technical scheme is that a kind of backlight module, including FPC (4), light guide plate, light source (5), reflector plate (1) and be attached to the glue frame (2) on reflector plate (1), described FPC(4), light guide plate and light source (5) be placed among described glue frame (2).
Preferably, described reflector plate (1) with at the attaching of glue frame (2) and FPC(4) be connected by a glue (3) with at the attaching of light source (5), connect and substitute conventional sticking double faced adhesive tape.
Compared with prior art, backlight module provided by the utility model, the structure reflector plate used is connected with the attaching of glue frame, light source is connected with being respectively adopted a glue at the attaching of FPC, substitute original double faced adhesive tape connected mode, effectively avoid cutting excessive glue is bad, viscosity is not enough and reliability floats and causes light leak, improve optical quality and assemble degree of accuracy because of double faced adhesive tape.

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 clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art is obtained on the premise of not making creative work, broadly fall into protection domain of the present utility model.
Generally in backlight module, reflector plate (1) with at the attaching of glue frame (2) and FPC(4) generally use double faced adhesive tape to connect with being connected at the attaching of light source (5), such as transparent double face glue or black and white double faced adhesive tape, and cut that excessive glue is bad and the not enough risk that backlight will be caused to have light leak of viscosity owing to double faced adhesive tape there will be, double faced adhesive tape also has reliability and floats phenomenon simultaneously, when attaching Wedge shape light conduction board, the joint face of light guide plate and glue frame joint face will be aggravated not at the probability of happening of sustained height plane, strong influence optical quality.
In this utility model, backlight module is connecting at attaching by a glue (3) connection.
Further, described reflector plate (1) with at the attaching of glue frame (2) and FPC(4) be connected by a glue (3) with at the attaching of light source (5).
Embodiment one:
As in figure 2 it is shown, reflector plate (1) attaches with glue frame (2), the point attached with reflector plate (1) inside glue frame, carry out a glue (31) and process.
Embodiment two:
As it is shown on figure 3, reflector plate (1) attaches with glue frame (2), it is provided with a strip groove in glue frame (2) bottom side, in groove, is provided with a glue (32) thus completes the attaching of reflector plate (1) and glue frame (2).
Embodiment three:
As shown in Figures 4 and 5, FPC(4) with carry out a glue (33) at light source (5) attaching and be connected.
This utility model passes through, conventional double faced adhesive tape is attached to be connect to use some glue connection to substitute at attachment structure, as reflector plate be connected with the attaching of glue frame, light source is connected with the attaching of FPC, avoids cutting excessive glue is bad, viscosity is not enough and reliability floats and causes light leak, improve optical quality and assemble degree of accuracy because of double faced adhesive tape from root.
Below it is only the detailed description of the invention of the present invention; not the present invention is done any pro forma restriction; any simple modification, equivalent variations that embodiment of above is done by every technical spirit according to the present invention, combine or modify, all still fall within the protection domain of technical solution of the present invention.
Claims (2)
