Cause heat dissipating state bad, heat cannot timely dissipate for a long time, can cause the blooming pieces such as diffusion sheet on light guide plate because
High temperature is deformed upon, for example, slightly heave, and then influences the image quality of display；And lamp bar long-time hot operation, can make
The life-span of liquid crystal display is reduced, and LED life-span also can be impacted.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight and liquid crystal display module.Should
Backlight pastes radiating film between the FPC of light emitting source and the side of metal frame, and extension pastes metal frame bottom surface
On inner surface, radiating effect is good, and the sticking effect of radiating film is stable, and production cost is low, it is easy to volume production, will not also be golden
Belong to the burrs on edges of frame to scratch.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including metal frame, the metal frame have bottom surface and side；Glue frame is provided with the metal frame
With the light guide plate in the glue frame, light emitting source is provided with the incidence surface of the light guide plate；The light emitting source includes FPC and welding
Luminescent device on the FPC, radiating films of the FPC away from luminescent device side is pasted onto, the radiating film glues
It is attached on the side of metal frame and is pasted after extending on the inner surface of the metal frame bottom surface.
Further, there are some through holes on the radiating film.
Further, the radiating film is graphite flake.
Further, side of the light guide plate away from exiting surface is provided with reflector plate.
Further, an at least optical film is provided with the exiting surface of the light guide plate.
Further, it is provided with anti-dazzling screen in the glue frame.
A kind of liquid crystal display module, including above-mentioned backlight.
The utility model has the advantages that：The backlight pastes the film that radiates the FPC and metal of light emitting source
Between the side of frame, and extension is pasted on the inner surface of metal frame bottom surface, and radiating effect is good, the sticking effect for the film that radiates
It is stable, and production cost is low, it is easy to volume production, will not also be by the burrs on edges of metal frame to scratch；Also solve metal frame and dissipate
The air bubble problem that hot film exists when pasting.
Brief description of the drawings

Fig. 2 is the A-A profiles of backlight shown in Fig. 1；
Fig. 3 is the B-B profiles of backlight shown in Fig. 1；
The schematic diagram for the radiating film that Fig. 4 provides for the utility model.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment 1
As Figure 1-3, a kind of backlight, including metal frame 1, the metal frame 1 have bottom surface and side；The metal
It is provided with frame 1 on the light guide plate 3 in glue frame 2 and the glue frame 2, the incidence surface of the light guide plate 3 and is provided with light emitting source；It is described
Light emitting source includes FPC 4 and the luminescent device 5 being welded on the FPC 4, is pasted onto the FPC 4 away from luminescent device 5 one
The radiating film 6 of side, the radiating film 6 pastes on the side of metal frame 1 and the bottom surface of metal frame 1 is pasted after extending
Inner surface on.
The backlight pastes radiating film 6 between the FPC 4 of light emitting source and the side of metal frame 1, and extends stickup
Onto the inner surface of the bottom surface of metal frame 1, radiating effect is good, and the sticking effect of radiating film 6 is stable, and production cost is low, easily
In volume production；Radiating film 6 in the technical program can also paste metal frame after the top bending of the side of metal frame 1
On 1 outer surface, but the radiating film 6 of this mode is easily by the burrs on edges of the side of metal frame 1 to scratch.
The radiating film 6 should try one's best and cover the bottom surface of the metal frame 1, further, the film 6 that radiates its
Its three side can extend on other three sides for pasting the metal frame 1, can not only increase the radiating film 6 and paste
Stability, moreover it is possible to further increase it is described radiating film 6 cooling surface area.
The material of the metal frame 1 is tried one's best the good metal material of selection heat conductivility, such as iron, stainless steel, aluminium alloy
Etc. material, collaboration radiating can be played a part of together with the radiating film 6.
The FPC 4 and radiating film 6 can also be carried out preferably by heat conduction glue by double faced adhesive tape or other viscoses
Paste.
As shown in figure 4, there are some through holes 61 on the radiating film 6, when pasting the radiating film 6, if described
There is bubble between metal frame 1 and radiating film 6, then it can discharge at through hole 61 by way of extruding bubble, solution
The air bubble problem that metal frame of having determined 1 and radiating film 6 exist when pasting.
Affiliated through hole 61 can be the shape or irregular abnormity of the rule such as circular, oval, square, or
Person is both combinations, is not specifically limited herein.
The radiating film 6 is graphite flake, and the plane thermal conductivity of graphite flake is functional, quickly can produce luminescent device 5
