Description
Technical field
It the utility model is related to field of backlights, more particularly to a kind of backlight module.
Background technology
Heat conducting pipe is applied in the backlight module of display module as a kind of novel heat sink more and more widely, but
It is that it can not realize the bending of wide-angle the reason for being limited to heat conducting pipe self structure, therefore, otherwise heat conducting pipe is entirely set
In the glue frame of backlight module, otherwise it is entirely provided at outside the glue frame of backlight module.If heat conducting pipe is arranged on the glue of backlight module
In frame, its heat absorbing end can be contacted directly with lamp bar, but its radiating end can only be radiated in glue frame；If heat conducting pipe is arranged on the back of the body
Outside the glue frame of optical module, its radiating end is directly radiated outside glue frame, but its heat absorbing end can only be arranged on glue frame outer surface and lean on
On the position of low beam bar, can not directly it be contacted with lamp bar.Howsoever, the thermolysis of heat conducting pipe can not all perform to maximum.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight module, the heat absorption of its heat conducting pipe
End is directly contacted with lamp bar, and radiating end is radiated outside glue frame, the thermolysis of heat conducting pipe can be performed into maximum.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight module, including glue frame, the light guide plate that is arranged in the glue frame and be arranged on the light guide plate and enter light
The lamp bar in face, in addition to the heat conducting pipe with the glue frame by Shooting Technique integrated setting, the heat absorbing end of the heat conducting pipe are set
Put the inner surface in the glue frame and paste the lamp bar, the radiating end of the heat conducting pipe pass through be arranged on after the glue frame it is described
The outer surface of glue frame.
Further, the heat conducting pipe has one or two radiating end.
Further, the lamp bar is pasted onto by heat-conducting glue in the heat absorbing end of the heat conducting pipe.
Further, the radiating end of the heat conducting pipe extends to the described one end of glue frame outer surface away from the lamp bar.
Further, the vapourizing temperature of the condensate liquid in the heat conducting pipe is more than 85 DEG C.
Further, an at least optical film is provided with the exiting surface of the light guide plate.
Further, it is provided with reflector plate in one side of the light guide plate away from exiting surface.
Further, it is provided with anti-dazzling screen on the glue frame.
The utility model has the advantages that：It is provided with the backlight module and passes through Shooting Technique one with the glue frame
The heat conducting pipe that bodyization is set, the heat absorbing end of the heat conducting pipe are located on the inner surface of the glue frame, directly contacted with lamp bar, radiate
Radiated from outside on the outer surface of the glue frame, the thermolysis of heat conducting pipe can be performed to maximum in end.
Brief description of the drawings
Fig. 1 is the diagrammatic cross-section of backlight module provided by the utility model；
Fig. 2 is the schematic rear view of backlight module provided by the utility model.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As illustrated in fig. 1 and 2, a kind of backlight module, including glue frame 1, the light guide plate 2 that is arranged in the glue frame 1 and set
In the lamp bar 3 of the incidence surface of light guide plate 2, in addition to the heat conducting pipe 4 with the glue frame 1 by Shooting Technique integrated setting,
The heat absorbing end 41 of the heat conducting pipe 4 is arranged on the inner surface of the glue frame 1 and pastes the lamp bar 3, the radiating of the heat conducting pipe 4
End 42 is arranged on the outer surface of the glue frame 1 after passing through the glue frame 1.
The heat conducting pipe 4 by Shooting Technique integrated setting, the heat conduction with the glue frame 1 are provided with the backlight module
The heat absorbing end 41 of pipe 4 is located on the inner surface of the glue frame 1, is directly contacted with lamp bar 3, and radiating end 42 is located at the glue frame 1
On outer surface, radiated from outside, the thermolysis of heat conducting pipe 4 can be performed to maximum.
The heat conducting pipe 4 has one or two radiating end 42, in the present embodiment, as inhaling among the heat conducting pipe 4
Hot junction 41, both ends are as radiating end 42.
The lamp bar 3 is preferably but not limited to be pasted onto in the heat absorbing end 41 of the heat conducting pipe 4 by heat-conducting glue.
The radiating end 42 of the heat conducting pipe 4 extends to the one end of the outer surface of glue frame 1 away from the lamp bar 3.
The vapourizing temperature of condensate liquid in the heat conducting pipe 4 is more than 85 DEG C, the vapour of the condensate liquid in general heat conducting pipe
Change temperature at 40 DEG C or so, can be prevented using the higher condensate liquid of vapourizing temperature when backlight module is in hot environment in this case
During work, condensate liquid all vaporization and can not liquefy again, the problem of heat conducting pipe 4 can not realize thermolysis, occurs.
An at least optical film 5 is provided with the exiting surface of the light guide plate 2, on the exiting surface of the general light guide plate 2 according to
It is secondary to be provided with diffusion barrier, lower bright enhancement film and upper bright enhancement film, certainly, depending on the visual demand of number amount and type of the optical film 5, no
Should be as limit；Reflector plate 6 is provided with the one side of the light guide plate 2 away from exiting surface；Anti-dazzling screen is provided with the glue frame 1
7, the anti-dazzling screen 7 is two-sided to have viscosity, and it is black backwards to the one side of the glue frame 1, and it is towards the one side of the glue frame 1
Black, white or other colors.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model patent scope can not be interpreted as, as long as using equivalent substitution or the form of equivalent transformation institute
The technical scheme of acquisition, it all should fall within the scope of protection of the utility model.
