Abstract
The utility model discloses a backlight and liquid crystal display module. This backlight includes the frame and sets up light guide plate in the frame, be provided with luminescent device between the income plain noodles of light guide plate and the frame, the frame is pasted in the one side on the play plain noodles of keeping away from the light guide plate has the fin. This backlight will on the frame is directly pasted to the fin, prevent that the reliability is higher because the thermal contraction nature that receives of fin and other diaphragms different and produce the membrane scheduling problem that wrinkles.
Description
Technical field
This utility model is related to field of liquid crystal display, more particularly to a kind of backlight and liquid crystal display module.
Background technology
Operationally, its LED lamp bar can generate heat the backlight of liquid crystal display, and relatively closed structure is led inside backlight
Cause heat dissipating state bad, heat long-time cannot timely dissipate, 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 affects the image quality for showing；And lamp bar long-time hot operation, can make
The life-span of liquid crystal display is reduced.
In the prior art, typically can paste fin at the back side of backlight to accelerate the radiating effect inside backlight
Really, there is the backlight of brandreth, fin can paste the back side of brandreth, and the backlight without brandreth, fin can paste reflection
The back side of piece.For without brandreth backlight, reflector plate can be produced after heat is absorbed with fin because contractility is different
The bad problems such as life is arched upward, film wrinkle, impact to display effect；And fin does not have and LED directly contacts, fin
Radiating effect is unable to reach most preferably.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides a kind of backlight and liquid crystal display module.Should
Backlight is adhered directly onto the fin on framework, prevents because fin is different from the heat shrinkable of other diaphragms
The problems such as generation film wrinkles, reliability is higher.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including framework and the light guide plate being arranged in the framework, the incidence surface and frame of the light guide plate
Luminescent device is provided between frame, the framework is pasted with fin in the side of the exiting surface away from light guide plate.
Further, the light guide plate is provided with reflector plate away from the side of exiting surface.
Further, heat conduction gemel connection is passed through between the luminescent device and fin.
Further, an at least blooming is provided with the exiting surface of the light guide plate.
Further, the framework is pasted with brake sack in the side of the exiting surface near light guide plate.
Further, the luminescent device is connected with FPC.
A kind of liquid crystal display module, including above-mentioned backlight.
This utility model has the advantages that：
（1）The fin of the backlight is adhered directly onto on the framework, and reliability is higher, will not because of fin and its
The heat shrinkable of its diaphragm is different and the problems such as produce film and wrinkle；
（2）By heat conduction gemel connection luminescent device and fin, the heat that directly can be produced the luminescent device is fast
It is transmitted to fastly on the fin, and is distributed heat in external environment by the fin, strengthens radiating effect.
Description of the drawings
The structure chart of the backlight that Fig. 1 is provided for this utility model；
The structure chart of another backlight that Fig. 2 is provided for this utility model.
Specific embodiment
This utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment 1
As shown in figure 1, a kind of backlight, including framework 1 and the light guide plate 2 being arranged in the framework 1, the light guide plate
Luminescent device 3 is provided between 2 incidence surface and framework 1, the framework 1 is pasted in the side of the exiting surface away from light guide plate 2
There is fin 4.
The fin 4 of the backlight preferably but is not limited to be adhered directly onto on the framework 1 by double faced adhesive tape, and existing
The technical scheme pasted fin on reflector plate in technology is compared, and reliability is higher, will not because of fin 4 and other
The heat shrinkable of diaphragm is different and the problems such as produce film and wrinkle.
The light guide plate 2 is provided with reflector plate 5 away from the side of exiting surface, and it is described that the reflector plate 5 directly assembles placement
On fin 4, because the reflector plate 5 and fin 4 are not pasted together, even if both contact with each other, be also not in
The bad problems such as the film wrinkle that heat shrinkable is different and produces.
As shown in Fig. 2 as the further optimization of the technical program, by leading between the luminescent device 3 and fin 4
Hot glue 9 connects, and only need to reduce the reflector plate 5 into light guide plate 2, and the reflector plate 5 should at least cover the VA of the backlight
Region, optimal case is that side of the reflector plate 5 on light source extreme direction is consistent with the side of the light guide plate 2.
The heat-conducting glue 9 connects luminescent device 3 and fin 4, and the heat that directly can be produced the luminescent device 3 is fast
It is transmitted to fastly on the fin 4, and is distributed heat in external environment by the fin 4, strengthens radiating effect.
It is provided with an at least blooming 6 on the exiting surface of the light guide plate 2, in the present embodiment, the light guide plate 2 goes out light
Diffusion barrier, lower bright enhancement film and upper bright enhancement film are disposed with face, but, the quantity and type of the blooming can be according to reality
Depending on demand, should not be limited with the present embodiment.
The framework 1 is pasted with brake sack 7 in the side of the exiting surface near light guide plate 2, and the brake sack 7 is two-sided
Glue, preferably black double faced adhesive tape, or the side towards the luminescent device 3 are black flour, dorsad the luminescent device 3
Side is the double faced adhesive tape in other color faces.
The luminescent device 3 is connected with FPC 8, and for connecting power supply, the luminescent device 3 is preferably LED.
Embodiment 2
A kind of liquid crystal display module, including the backlight described in embodiment 1.
Embodiment described above only expresses embodiment of the present utility model, and its description is more concrete and detailed, but and
Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as the institute in the form of equivalent or equivalent transformation
The technical scheme of acquisition, all should fall within protection domain of the present utility model.
