Abstract
The utility model discloses a kind of Novel backlight mould group, it include: reflectance coating, shading glue, glue frame, FPC, several LED light, light guide plate, diffusion barrier and optical diaphragm assembly, the light guide plate incidence surface is in the obtuse angle isosceles triangular structure to concave, several irregular broached-tooth designs are formed on the light guide plate incidence surface, two vertex of the light guide plate incidence surface are equipped with the notch that can accommodate the LED light.The utility model can reduce the use of LED light, save cost and simplify production process；The width of backlight source module is reduced, screen accounting is promoted；So that the point light source that the LED light of a small amount of number projects is converted to, light is uniform, the enough area sources of brightness.
Description
Technical field
The utility model relates to display module technical field more particularly to a kind of Novel backlight mould groups.
Background technique
In the prior art, light guide plate is mostly the rectangular configuration of rule, and several LED light are welded on FPC, and FPC passes through two-sided
Be adhesive in light guide plate on one side, the angle of LED light emergent light is 120 °, the light that LED light issues be incident to after light guide plate through refraction and
Reflection can lose significant portion.The width of LED light is the main reason for influencing backlight module non-light-emitting surface width, to influence end
The screen accounting of end equipment.In order to promote screen accounting, practices well is the width for reducing LED light.But the more thinner narrower then valence of LED light
Lattice are more expensive, higher cost.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of Novel backlight mould group.
The technical solution of the utility model is as follows: the utility model provides a kind of Novel backlight mould group, comprising: reflection
Film, shading glue, glue frame, FPC, several LED light, light guide plate, diffusion barrier and optical diaphragm assembly, the light guide plate incidence surface be in
The obtuse angle isosceles triangular structure of indent is formed with several irregular broached-tooth designs, the leaded light on the light guide plate incidence surface
Two vertex of plate incidence surface are equipped with the notch that can accommodate the LED light.
Further, the broached-tooth design is triangle, semicircle, half elliptic or trapezoidal.
Further, the broached-tooth design is according to the distance apart from the LED light, from closely to remote in by dredging to close distribution.
Further, the depth of the broached-tooth design is according to the distance apart from the LED light, from the near to the remote in incremental shape
State.
Further, the indentation, there is equipped with the 1-2 LED light.
Further, the emergent light angle of the LED light is 8 ° -12 °.
Preferably, the emergent light angle of the LED light is 10 °.
It further, is in opposite with the light guide plate incidence surface on the inside of the corresponding glue frame at the light guide plate incidence surface
The obtuse angle isosceles triangular structure answered.
Using the above scheme, the utility model can reduce the use of LED light, save cost and simplify production process；Drop
The width of low backlight source module promotes screen accounting；So that the point light source that the LED light of a small amount of number projects be converted to light uniformly,
The enough area sources of brightness.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the enlarged drawing in Fig. 1 at A.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 and Fig. 2 are please referred to, the utility model provides a kind of Novel backlight mould group, comprising: reflectance coating (not indicating),
Shading glue 2, glue frame 3, FPC (not indicating), several LED light 5, light guide plate 4, diffusion barrier 1 and optical diaphragm assembly (not indicating), institute
Stating 4 incidence surface of light guide plate is in the obtuse angle isosceles triangular structure that concaves, is formed with and several does not advise on 4 incidence surface of light guide plate
Then broached-tooth design 41, the broached-tooth design 41 can be triangle, semicircle, half elliptic or trapezoidal etc., according to described in distance
The distance of LED light 5, from closely to remote in by dredging to close distribution；And the depth of the broached-tooth design 41 is according to apart from the LED light 5
Distance, from the near to the remote in be incremented by state, the backlight source module emitting brightness can be promoted and make light uniform.It is described
Light guide plate 4 incidence surface, two vertex are equipped with the notch that can accommodate the LED light 5, can accommodate the 1-2 LED light, will
Two corner positions of the light guide plate 4 are arranged in the LED light 5, can reduce the width of backlight source module, increase light-emitting surface
Cost is improved in region.The emergent light angle of the LED light 5 is 8 ° -12 °, preferably 10 °.At 4 incidence surface of light guide plate pair
It is in obtuse angle isosceles triangular structure corresponding with 4 incidence surface of light guide plate on the inside of the glue frame 3 answered, can helps to fix
With the protection light guide plate 4 and LED light 5.
In conclusion the utility model can reduce the use of LED light, saves cost and simplify production process；Reduce back
The width of light source module group promotes screen accounting；So that the point light source that the LED light of a small amount of number projects be converted to light uniformly, brightness
Enough area sources.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
