Abstract
The utility model discloses a kind of Novel backlight mould group, it include: reflectance coating, glue frame, light-strip, shading glue, FPC, several LED light, light guide plate, diffusion barrier and optical diaphragm assembly, the light guide plate is set in the glue frame, the light-strip is set between the incidence surface and the glue frame of the light guide plate, the light-strip is in rectangular configuration, the LED light is set to light-strip narrow side both ends, and the light-strip is equipped with several broached-tooth designs on the side far from the light guide plate side.The utility model can convert point light source to that light is uniform, the enough area sources of brightness；With save the cost and production process can be simplified；Mould group width can be reduced and promote screen accounting.
Description
Technical field
The utility model relates to display module technical field more particularly to a kind of Novel backlight mould groups.
Background technique
Existing backlight module, general structure are that several LED light are welded on FPC, and FPC is led by two-sided be adhesive in
On one side, significant portion can be lost to tabula rasa by being reflected and being reflected after the light guide tabula rasa that LED light issues, and backlight module goes out the equal of light
Even property effect is not fully up to expectations.And the terminal device for the development of the times, possessing high screen accounting screen is increasingly chased after
It holds in both hands, and backlight module is affected to the screen accounting of entire screen, and how cost of implementation is lower and terminal device can be made to gather around
There is the backlight module of high screen accounting to remain the direction that industry is pursued and made great efforts.
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: a kind of Novel backlight mould group, comprising: reflectance coating, glue frame, light-strip,
Shading glue, FPC, several LED light, light guide plate, diffusion barrier and optical diaphragm assembly, the light guide plate are set in the glue frame, institute
Light-strip is stated between the incidence surface and the glue frame of the light guide plate, the light-strip is in rectangular configuration, and the LED light is set
Light-strip narrow side both ends are placed in, the light-strip is equipped with several broached-tooth designs on the side far from the light guide plate side.
Further, the broached-tooth design is according to the distance apart from the LED light, from the near to the remote in by dredging 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 shape of the broached-tooth design is triangle, semicircle, half elliptic or trapezoidal.
Further, light-strip narrow side both ends are respectively provided with the 1-2 LED light.
Further, the width of the light-strip is 0.7mm-1.0mm.
Using the above scheme, the utility model can convert point light source to that light is uniform, the enough area sources of brightness；It can be with
Save the cost and simplified production process；Mould group width can be reduced and promote screen accounting.
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),
Glue frame 3, light-strip 6, shading glue 2, FPC (not indicating), several LED light 5, light guide plate 4, diffusion barrier 1 and optical diaphragm assembly are (not
Mark), the light guide plate 4 is set in the glue frame 3, incidence surface and the glue frame of the light-strip 6 set on the light guide plate 4
Between 3, the light-strip 6 is in rectangular configuration, and between 0.7mm-1.0mm, material can be selected and 4 phase of light guide plate width
Same material, can also select the material different from the light guide plate 4.The LED light 5 is set to 6 narrow side two of light-strip
It end, can be with while being capable of providing enough brightness by the way that 1-2 LED light 5 are respectively arranged at the 6 narrow side both ends of light-strip
The use for reducing the LED light 5 is conducive to save the cost and simplifies production process, while can reduce the width of mould group, improves
Shield accounting.The light-strip 6 is equipped with several broached-tooth designs 61 on the side far from 4 side of light guide plate.The broached-tooth design
61 according to the distance apart from the LED light 5, from the near to the remote in by dredging close distribution, the depth of the broached-tooth design 61 according to away from
With a distance from the LED light 5, from the near to the remote in state is incremented by, there is good focusing light effect, it can will be described in a small amount of number
The point light source that LED light 5 projects is converted into the enough area sources of uniform in light emission, intensity.61 shapes of the broached-tooth design can be
Triangle, semicircle, half elliptic or trapezoidal.
In conclusion the utility model can convert point light source to, light is uniform, the enough area sources of brightness；It can save
Cost and simplified production process；Mould group width can be reduced and promote screen accounting.
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.
