Description
【Technical field】
The utility model is related to a kind of LED-backlit module device, particularly to a kind of side entering-type LED backlight module.
【Background technology】
For traditional side entering-type LED backlight module, the light that LED chip sends can not fully enter light guide plate, on the one hand,
A part of light can not be projected from the light output surface of LED encapsulation due to total internal reflection.On the other hand, even if encapsulating from LED
Light output surface project light, a part of light is due to the reflection of light guide plate light-entering surface, and can not enter light guide plate, LED encapsulation and
Coupled modes between light guide plate and efficiency need to improve further.For this reason, a kind of it is proposed that side entering-type LED backlight module.
【Utility model content】
Main purpose of the present utility model is to provide a kind of side entering-type LED backlight module, by light guide plate and LED encapsulation
Between formed coupled modes so that coupling efficiency is higher, LED encapsulation light output surface at there is no total internal reflection,
Also reflection is there is no, the light that LED chip sends substantially all entrance light guide plate, due to not having at light guide plate light-entering surface
Total internal reflection, the light of the wide-angle that LED chip sends, and wherein sets it is easy to reach the uniformity of brightness also into light guide plate
Some brightness enhancement film and diffusion barrier it is ensured that in the case of same brightness, the quantity of LED encapsulation used about reduces, reduces cost,
The rising angle of LED encapsulation increases, can be with the problem in effectively solving background technology.
For achieving the above object, the technical scheme that the utility model is taken is：
A kind of side entering-type LED backlight module, including light source, bottom reflector plate and brightness enhancement film, described bottom reflector plate side is provided with
Light source, is provided with light guide plate above the reflector plate of described bottom, is provided with brightness enhancement film above described light guide plate, and described brightness enhancement film lower surface is provided with
Diffusion barrier, is provided with glass substrate above described brightness enhancement film.
Further, described bottom surface of light guide plate is provided with site.
Further, described light guide plate, diffusion barrier and brightness enhancement film are arranged between bottom reflector plate and glass substrate.
Further, coupled modes are formed between described light guide plate and LED encapsulation.
Compared with prior art, the utility model has the advantages that：By being formed between light guide plate and LED encapsulation
Coupled modes, so that coupling efficiency is higher, there is no total internal reflection at the light output surface of LED encapsulation, enter in light guide plate
Also reflection is there is no, the light that LED chip sends substantially all entrance light guide plate, due to entirely interior not anti-at optical surface
Penetrate, the light of the wide-angle that LED chip sends also into light guide plate it is easy to reach the uniformity of brightness, and the increasing being provided with
Bright film and diffusion barrier are it is ensured that in the case of same brightness, the quantity of LED encapsulation used about reduces, reduces cost, and LED encapsulates
Rising angle increase.

In conjunction with specific embodiment, the utility model is expanded on further.
As shown in Figure 1-2, a kind of side entering-type LED backlight module, including light source 1, bottom reflector plate 2 and brightness enhancement film 5, described bottom
Reflector plate 2 side is provided with light source 1, is provided with light guide plate 3, is provided with brightness enhancement film 5 above described light guide plate 3 above described bottom reflector plate 2,
Described brightness enhancement film 5 lower surface is provided with diffusion barrier 4, is provided with glass substrate 6, described light guide plate 3 bottom surface sets above described brightness enhancement film 5
There is site, described light guide plate 3, diffusion barrier 4 and brightness enhancement film 5 are arranged between bottom reflector plate 2 and glass substrate 6, described light guide plate 3
Form coupled modes and LED encapsulation between.
The utility model side entering-type LED backlight module, by light guide plate 3 and LED encapsulation between formed coupled modes so that
Coupling efficiency is higher, there is no total internal reflection at the light output surface of LED encapsulation, also base at light guide plate 3 light-entering surface
Do not reflect in basis, the light that LED chip sends substantially all entrance light guide plate, due to not having total internal reflection, LED chip sends
Wide-angle light also into light guide plate it is easy to reach the uniformity of brightness, and the brightness enhancement film 5 that is provided with and diffusion barrier 4,
In the case of ensureing same brightness, the quantity of LED encapsulation used about reduces, reduces cost, and the rising angle of LED encapsulation adds
Greatly.
Wherein, described light guide plate 3 bottom surface is provided with site, and what LED encapsulation sent is optically coupled into light guide plate 3, by anti-
Penetrate reflection and the scattering of piece and site, propagate to liquid crystal display direction.
Wherein, described light guide plate 3, diffusion barrier 4 and brightness enhancement film 5 are arranged between bottom reflector plate 2 and glass substrate 6, improve
