Optimal viewing effect can be provided, and presentation ability of the common display device in terms of screen edge is relatively not ideal,
The curved design of curved-surface display device full wafer screen, it is possible to provide broad full-view image effect, brings to user and preferably regards
Feel and enjoy.
It is main in prior art to realize curved surface using light guide plate natural torsion and by the way of oppressing liquid crystal panel using front frame
Show.But these fixed forms are simultaneously unstable, light guide plate is susceptible to deformation, affects display effect, but frame narrows,
Cause backlight bright line problem occurred frequently, occur especially in the bright line of backlight both sides, when light is incident from the left side of light guide plate,
Most light from the right side outgoing of light guide plate, and can appear backlight after the isostructural multipath reflection of glue frame, cause
Bright line phenomenon, as guide-lighting board size constantly reduces, this offside bright line problem can be increasingly severe, it is therefore desirable to finds more preferably
Back light source structure it is little to solve the problems, such as bright line and viewing area.
The content of the invention
This utility model purpose is：A kind of back light source structure is provided, including light source, light guide plate, diffusion layer, lustre adding layer and frame
Body, it is characterised in that the framework is provided with the groove that can place the luminous source, institute towards the light guide plate incidence surface side
Light source is stated in the groove, the light guide plate includes central plane, first side and second side, the first side in incidence surface
Face and the symmetrical curved curved surface of second side, stack reflector plate, light guide plate, diffusion layer and increasing in the framework from the bottom to top successively
The light guide plate, diffusion layer, lustre adding layer are fixed together by photosphere, the framework.Further, the blooming piece includes one
Diffusion layer and two lustre adding layers.
Further, the light guide plate and the diffusion layer, lustre adding layer, framework have in the first side and second side
There is the curvature of identical.
Further, the diffusion layer, lustre adding layer, framework do not surpass in the radius of curvature of the first side and second side
Cross 12mm.
Further, the reflector plate is more than the light guide plate, diffusion in the extension of the first side, second side
The length of layer and lustre adding layer.
Further, also including the shading glue being arranged on the outside of the framework, the shading glue is used for limiting the light source
Output optical zone domain.
This utility model is by light guide plate, reflector plate, diffusion layer.Lustre adding layer is fixed together, and light guide plate is not susceptible to deformation,
Light guide plate arranges cambers away from two sides of light source, the light sent by exiting surface is reflected to different directions, reflection and
Scattering, so that light more disperses, brightness during backlight display image is more uniform, meanwhile, light is matched somebody with somebody after breaing up
Close shading glue to use, can effectively mitigate the bright line problem of backlight, can also form backlight module width in the case of narrow frame and regard
Angle, the uniform display effect of printing opacity.

Specific embodiment
Embodiment 1：As shown in figure 1, a kind of back light source structure, including light source 04, light guide plate 03, diffusion layer 05, lustre adding layer
06 and framework 01, framework 01 is provided with the groove that can place light source 04, the light source position towards the light guide plate incidence surface side
In groove, light guide plate 03 includes central plane 09, first side 09 and second side 10, first side 09 and in incidence surface
10 symmetrical curved curved surface of two side faces, stacks reflector plate 02, light guide plate 03, diffusion layer 05 from the bottom to top successively and increases in framework 01
Photosphere 06.
Further, light guide plate 03 and diffusion layer 05, lustre adding layer 06, framework 01 have in first side 10 and second side 11
There is the curvature of identical.By being provided for changing the arc-shaped curved surface of opticpath on the incidence surface of light guide plate 03, thus, leading
The light of light intralaminar part central plane 09, first side 09, second side 10 can promptly with approximate collimated light mode to
Blooming piece is projected, and the point source launched by light source is formed as area source after light guide plate 03, generally also includes in backlight
For the diffusion layer 05 of diffusing light, the light sent by the exiting surface of light guide plate 03 is reflected to different directions, reflects and is dissipated
Penetrate.Less light losing so that exiting surface amount of light increases, and improves out the brightness of light.
In the present embodiment, backlight also includes being arranged on the shading glue 07 on the outside of light source 04, and shading glue 07 is used for limiting
The output optical zone domain of the light source.Diffusion layer 05 is may be contained within above light guide plate 03 with lustre adding layer 06, and diffusion layer 05 is led for diffusion
The light sent by the exiting surface of tabula rasa 03.Lustre adding layer 06 is arranged on above diffusion layer 05, wherein, light guide plate 03, blooming piece
05 and framework 01 first side 09 and second side 10 radius of curvature be less than 12mm.Reflector plate 02 extends beyond light guide plate
03, reflector plate 02 is fixedly connected with framework 01, while light guide plate 03, diffusion layer 05, lustre adding layer 06 are fixed together by framework 01.
Meanwhile, reflector plate 02 is more than light guide plate 03, diffusion layer 05 and lustre adding layer 06 in the extension of first side 09, second side 10
Length.Compare with back light source structure in prior art, this utility model backlight is realizing the expansion to light using globoidal structure
When scattered, the light for sending the exiting surface of light guide plate to greatest extent is reflected to different directions, reflects and is scattered, so that
Light more disperses, brightness during liquid crystal panel display image more uniformly with concentration, visually increase in viewing area, coordinate
Shading glue use can prevent the appearance of backlight module bright line.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent transformation are formed
Technical scheme, all fall within this utility model it is claimed within the scope of.
