Utility model content
The utility model is shone using side entering type mainly solving the technical problems that provide a kind of backlight of television source device
Form, so that light is uniformly distributed in entire liquid crystal display panel by light guide plate, further increase the contrast of picture, enhancing is aobvious
Show effect.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of television set back
Light supply apparatus, including light guide plate, light source, reflector, reflectance coating, the first diffusion barrier, the second diffusion barrier, bright enhancement film and liquid crystal surface
Plate, the light source are separately positioned on the two sides of light guide plate width direction, and the reflector is wrapped in the outer side edges of light source
And be connected with the reflectance coating of light guide plate bottom, first diffusion barrier, bright enhancement film and the second diffusion barrier are respectively successively from upper
It is superposed under in the upper end of light guide plate, the liquid crystal display panel is connected with the first diffusion barrier.
In one preferred embodiment of the utility model, the light source uses the coil structure of multiple LED composition, multiple
The LED arranges in matrix.
In one preferred embodiment of the utility model, the bright enhancement film uses prismatic lens.
In one preferred embodiment of the utility model, the reflector uses arcuate structure.
In one preferred embodiment of the utility model, the reflector and reflectance coating use integrated formed structure.
In one preferred embodiment of the utility model, the dot pattern for reflecting light is provided on the light guide plate.
In one preferred embodiment of the utility model, the material of the light guide plate is acrylic resin.
The beneficial effects of the utility model are: the backlight of television source device of the utility model, is shone using side entering type
Form makes light uniformly be distributed in entire liquid crystal display panel by light guide plate, further increases the contrast of picture, enhancing display
Effect.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the cross-sectional view of a preferred embodiment of the utility model backlight of television source device；
The label in accompanying drawing is: 1, light guide plate, 2, light source, 3, reflector, 4, reflectance coating, the 5, first diffusion barrier, 6, second
Diffusion barrier, 7, bright enhancement film, 8, liquid crystal display panel.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
As shown in Figure 1, the utility model embodiment includes:
A kind of backlight of television source device, including light guide plate 1, light source 2, reflector 3, reflectance coating 4, the first diffusion barrier 5,
Two diffusion barriers 6, bright enhancement film 7 and liquid crystal display panel 8, the light source 2 are separately positioned on the two sides of 1 width direction of light guide plate,
The reflector 3 is wrapped in the outer side edges of light source 2 and is connected with the reflectance coating 4 of 1 bottom of light guide plate, first diffusion
Film 5, bright enhancement film 7 and the second diffusion barrier 6 are successively superposed from top to bottom respectively in the upper end of light guide plate 1, the liquid crystal surface
Plate 8 is connected with the first diffusion barrier 5.
Among the above, the coil structure that the light source 2 is formed using multiple LED, multiple LED arrange in matrix,
The form to be shone using side entering type, makes light uniformly be distributed in entire liquid crystal display panel 8 by light guide plate 1.
Further, the reflector 3 uses arcuate structure.Wherein, the reflector 3 and reflectance coating 4 use one
Forming structure.Meanwhile the material of the light guide plate 1 is acrylic resin, being provided on the light guide plate 1 reflects light
Dot pattern (figure do not regard), further increase the contrast of picture, enhance display effect.
In the present embodiment, the bright enhancement film 7 uses prismatic lens, and brightening piece is used to improve 8 brightness of liquid crystal display panel, is divided into folding
Two kinds of emitting brightening piece (setting up prismatic lens) and fully-reflected type brightening piece (down-set prismatic lens).Refractive brightening piece is
Moldable resin diaphragm is transferred under high pressure, further enhances display effect.
In conclusion the backlight of television source device of the utility model, the form to be shone using side entering type, pass through light guide plate
So that light is uniformly distributed in entire liquid crystal display panel, further increase the contrast of picture, enhances display effect.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
