Solve bright border problem.
In order to achieve the above object, this utility model adopts the following technical scheme that
A kind of backlight module, the light source including glue frame, being arranged in described glue frame, the reflection being arranged in described glue frame
Sheet, being arranged at the light guide plate above described reflector plate, the edge of described reflector plate is pasted with one-side band glue secret note, described reflector plate
The side of close described light guide plate be provided with several equally distributed salient points.
As a kind of improvement of this utility model backlight module, generally circular in shape, rhombus, the triangle of described salient point, ellipse
Circular, circular or trapezoidal.
As a kind of improvement of this utility model backlight module, described glue frame is set to aluminum framework.
As a kind of improvement of this utility model backlight module, the outside of described glue frame is provided with several fin.
As a kind of improvement of this utility model backlight module, described fin is dentation groove.
As a kind of improvement of this utility model backlight module, the degree of depth of described dentation groove is 0.1mm-10mm, described
Spacing between dentation groove is 0.1mm-10mm.
As a kind of improvement of this utility model backlight module, described backlight module also includes that inverse edge concentration piece, positive rib are poly-
Mating plate and diffusion sheet, described inverse edge concentration piece is positioned over the top of described light guide plate, and the prism facets of described inverse edge concentration piece
End face towards described light guide plate；Described positive rib concentration piece is arranged at the top of described inverse edge concentration piece, and described diffusion sheet is arranged
Top in the prism facets of described positive rib concentration piece.
Relative to prior art, this utility model, by pasting one-side band glue secret note at the edge of reflector plate, relies on black
Glue with photo absorption performance, the light reflected at glue frame is done the process of absorption function, thus solves bright border thoroughly
Problem, has reached satisfied effect.So, it is possible to directly save the labor costs at edge, the mouth of a river of polishing light guide plate, and
Without high-accuracy injection machine, requiring to be substantially reduced to injection hardware device, the cost having saved hardware puts into.Several are uniform
The setting then adjustable light reflection angle of the salient point of distribution, to increase light service efficiency, and can improve overall backlight module
Brightness.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the part-structure figure in this utility model.
Detailed description of the invention
The most with reference to the accompanying drawings this utility model is further described.
As depicted in figs. 1 and 2, a kind of backlight module that this utility model provides, including glue frame 1, it is arranged in glue frame 1
Light source 2, the reflector plate 3 being arranged in glue frame 1, being arranged at the light guide plate 4 above reflector plate 3, the edge of reflector plate 3 is pasted with list
Wearing glue secret note 5, the side of the close light guide plate 4 of reflector plate 3 is provided with several equally distributed salient points 6.By in reflection
One-side band glue secret note 5 is pasted at the edge of sheet 3, rely on black glue with photo absorption performance, the light reflected at glue frame is done
The process of absorption function, thus solve bright border problem thoroughly, reach satisfied effect.Salient point 6 adjustable light is set
Line reflection angle, to increase light service efficiency, and can improve the brightness of overall backlight module.Light guide plate 4 is provided with incidence surface 41
With bottom surface 42, light source 2 is disposed in proximity to the side of incidence surface 41, and the light of light source 2 is injected from this incidence surface 41, then by light guide plate
4 injections, after the light that part is reflected by the bottom surface of light guide plate 4 is then by the reflective surface of reflector plate 3 to light guide plate 4, then by
The exiting surface injection of light guide plate 4, to reach the effect that light source shows.
Generally circular in shape, rhombus, triangle, the ellipse of salient point 6, circular or trapezoidal.
Glue frame 1 is set to aluminum framework.Aluminium material has more preferable heat conductivity and thermal diffusivity than plastic cement material.
The outside of glue frame 1 is provided with several fin 7.Fin 7 can increase area of dissipation, it is possible to promptly dissipation light
The heat energy that source 2 produces, is effectively reduced the temperature of light source 2 work, to ensure the service life of light source 2.
Fin 7 is dentation groove.The degree of depth of dentation groove is 0.1mm-10mm, and the spacing between dentation groove is
0.1mm-10mm.The fin 7 of this structure can increase area of dissipation effectively.
Backlight module also includes inverse edge concentration piece 8, positive rib concentration piece 9 and diffusion sheet 10, and inverse edge concentration piece 8 is positioned over leaded light
The top of plate 4, and the prism facets 81 of inverse edge concentration piece 8 is towards the end face (being inverted, i.e. prism facets is down) of light guide plate 4；Positive rib
Concentration piece 9 is arranged at the top of inverse edge concentration piece 8, and positive rib concentration piece 9 is for just to put (prism facets is upward), and diffusion sheet 10 is just arranged at
The top of the prism facets 91 of rib concentration piece 9.When light source 2 enters light via light guide plate 4, this light source 2 i.e. can reflected 3 and lead
The continuous reflection of tabula rasa 1, causes light source rising angle quite big, and the light source of big rising angle can be incident upon inverse edge optically focused completely
In the prism facets of sheet 8, owing to light is fully reflective on inverse edge concentration piece 8, any loss will not be produced so that loss-free light
After source is via the prism facets Complete Convergence of inverse edge concentration piece 8, center can be directed to, now, via the rib of positive rib concentration piece 9
Light source is restrained by minute surface again, can promote center briliancy, and then produce the backlight of maximum light source.
In a word, this utility model by the edge of reflector plate 3 paste one-side band glue secret note 5, rely on black glue institute with
Photo absorption performance, the light reflected at glue frame 1 is done the process of absorption function, thus has reached satisfied effect.So,
Can directly save the labor costs at the edge, the mouth of a river of polishing light guide plate 4, and without high-accuracy injection machine, to injection hardware
Equipment requirements is substantially reduced, and the cost having saved hardware puts into.The setting then adjustable light of several equally distributed salient points 6
Reflection angle, to increase light service efficiency, and can improve the brightness of overall backlight module.
The announcement of book and teaching according to the above description, this utility model those skilled in the art can also be to above-mentioned reality
The mode of executing carries out suitable change and amendment.Therefore, this utility model is not limited to disclosed and described above being embodied as
Modifications and changes more of the present utility model be should also be as falling in scope of the claims of the present utility model by mode.
