Abstract
The utility model discloses a kind of backlight and display module.The backlight include glue frame, be arranged in the glue frame light guide plate, be arranged on the light guide plate incidence surface lamp bar, the glue frame side front and/or the back side covered with one layer of thermal-radiating material.The backlight can actively carry out heat loss through radiation to heat caused by lamp bar, to reduce internal temperature, ensure that various functions are normal.
Description
Technical field
It the utility model is related to field of backlights, more particularly to a kind of backlight and display module.
Background technology
Liquid crystal display die set because can not self-luminous, so need coordinate backlight use, as market is to high brightness backlight
Pursuit, more and more using LED quantity in backlight, power is also increasing, and heat dispersion is for high brightness backlight
It is most important.
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 die set.Should
Backlight can actively carry out heat loss through radiation to heat caused by lamp bar, to reduce internal temperature, ensure that various functions are normal.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including glue frame, be arranged in the glue frame light guide plate, be arranged on the incidence surface of the light guide plate
Lamp bar, the glue frame side front and/or the back side covered with one layer of thermal-radiating material.
Further, the thermal-radiating material is carbon nanotube ink.
Further, the thickness of the thermal-radiating material is 5-10 μm.
Further, the thermal conductivity of the thermal-radiating material is 30W/mk.
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 positive thermal-radiating material in side of the glue frame.
A kind of display module, including above-mentioned backlight.
The utility model has the advantages that：The backlight is in the front of the glue frame side and/or back side overlying
One layer of thermal-radiating material of lid, the hot of infra-red radiation is actively outwards carried out using the thermal-radiating material, improves the glue frame
Heat emissivity coefficient, actively to carry out heat loss through radiation to internal heat, to reduce internal temperature, ensure that various functions are normal.
Brief description of the drawings
Fig. 1 is the schematic diagram of backlight provided by the utility model.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As shown in figure 1, a kind of backlight, including glue frame 1, be arranged in the glue frame 1 light guide plate 2, be arranged on it is described
The lamp bar 3 of the incidence surface of light guide plate 2, the front of the side of glue frame 1 and/or the back side are covered with one layer of thermal-radiating material 4.
The backlight covers one layer of thermal-radiating material 4 on the front of the side of glue frame 1 and/or the back side, using described
Thermal-radiating material 4 actively outwards carries out the hot of infra-red radiation, the heat emissivity coefficient of the glue frame 1 is improved, with to internal heat
Heat loss through radiation is actively carried out, to reduce internal temperature, ensures that various functions are normal.
The thermal-radiating material 4 can also be further covered on the lateral surface of the side of glue frame 1, if the glue frame 1
With bottom surface, then the thermal-radiating material 4 is also further covered on the outer surface of the bottom surface of glue frame 1.
The thermal-radiating material 4 is preferably carbon nanotube ink, and thickness is 5-10 μm, and its thermal conductivity is 30W/mk left
It is right.
It is provided with an at least optical film 5 on the exiting surface of the light guide plate 2, in the present embodiment, the light extraction of the light guide plate 2
Diffusion barrier, lower bright enhancement film and upper bright enhancement film are disposed with face, certainly, the visual demand of number amount and type of the optical film 5
Depending on, should not be as limit；Reflector plate 7 is provided with the one side of the light guide plate 2 away from exiting surface；The side of the glue frame 1
Anti-dazzling screen 6 is provided with positive thermal-radiating material 4, the anti-dazzling screen 6 is two-sided to be respectively provided with viscosity, backwards to the one of the glue frame 1
Face is black, and the one side towards the glue frame 1 is black, white or other colors.
The lamp bar 3 includes wiring board 31 and some luminescent devices 32 being arranged on the wiring board 31, the circuit
Plate 31 is pasted and fixed on the front of the positive and described light guide plate 2 of the side of glue frame 1；The anti-dazzling screen 6 and the circuit
One side of the plate 31 away from some luminescent devices 32 is pasted together, and the anti-dazzling screen 6 is preferably high heat conduction shading glue, is had
It is transmitted to beneficial to by heat caused by the lamp bar 3 on the thermal-radiating material 4.
The high heat conduction shading glue can be the black light-blocking film piece that graphite flake etc. has viscosity and high-termal conductivity, can also
It is the composite diaphragm that metal material is mixed with black shading glue；The luminescent device 32 is preferably LED.
Embodiment two
A kind of display module, including the backlight described in embodiment one.
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.
