Enough brightness and the light source being evenly distributed so that liquid crystal display panel can normally show image.
At present, large-sized backlight module is prevents from causing light guide plate dilatancy that can reserve due to hot and humid environment in
The gap of 0.2~0.3mm, still, the gap reserved can be such that light guide plate is moved during movement or carrying, far
From or close to lamp bar, different degrees of loss is had so as to cause module brightness, brightness is relatively low.If by reducing preset clearance
Improve backlight module brightness, then be easy to cause Hotspot phenomenons, that is, occur the high region of brightness and brightness it is low region it is alternate,
Make to form light and shade alternately multiple points on liquid crystal display panel, seriously affect display quality.
Invention content
In view of drawbacks described above of the prior art or deficiency, are intended to provide a kind of backlight module and display device, can solve
Certainly luminance loss's problem and improvement hotspot phenomenons.
In a first aspect, the embodiment of the present application provides a kind of backlight module, including light guide plate and lamp bar, which is characterized in that
Lamp bar is set at least side of backlight module, and backlight module is made to be formed with light source side and unglazed source,
Lamp bar includes the multiple LED light sources of wiring board and setting in the circuit board；
Backlight module further includes light transmission elastic layer,
Light transmission elastic layer is set between light guide plate and lamp bar so that gap is minimum between light guide plate and lamp bar.
In some embodiments, scattering particles is contained in light transmission elastic layer, scattering particles material includes following at least one：
PP、PET、PC。
In some embodiments, contain bubble in light transmission elastic layer.
Second aspect, the embodiment of the present application additionally provide a kind of display device, which respectively implements including the application
The backlight module that example provides.
Backlight module provided by the embodiments of the present application by setting light transmission elastic layer between light guide plate and lamp bar, is realized
Zero clearance between light guide plate and lamp bar so as to improve the light efficiency for entering light guide plate, reduces luminance loss.
The backlight module that some embodiments of the present application provide in light transmission elastic layer further by adding in scattering particles
Or bubble, it can be effectively by multiple LED light source uniform atomizings, the problem of slowing down or eliminate Hotspot, optimization shows quality.

Fig. 1 shows the structure diagram of the backlight module according to the embodiment of the present application.
As shown in Figure 1, a kind of backlight module, including light guide plate 1 and lamp bar 2,
Lamp bar 2 is set at least side of backlight module, and backlight module is made to be formed with light source side and unglazed source,
Lamp bar 2 includes the multiple LED light sources 21 of wiring board 22 and setting in the circuit board；
Backlight module further includes light transmission elastic layer 3,
Light transmission elastic layer 3 is set between light guide plate 1 and lamp bar 2 so that gap is minimum between light guide plate 1 and lamp bar 2.
In above-described embodiment, by setting light transmission elastic layer between light guide plate and lamp bar, substituted with the light transmission elastic layer
Original gap not only can be that light guide plate reserves dilatancy space, but also substantially reduce the distance between light guide plate and lamp bar,
Zero clearance between light guide plate and lamp bar is realized, the loss of light in reducing into light guide plate.
Further, light transmission elastic layer is made of elastic translucent material.
In the present embodiment, elastic translucent material is not limited to a certain or different materials, can be that arbitrary translucency is good
Material good and with elastic property.
Further, elastic translucent material includes following at least one：PMMA, MS, PC, PET, UV glue.
