The utility model proposes a kind of backlight module.
In the utility model embodiment, referring to Figures 1 and 2, the backlight module includes：
Backlight 1；
Light guide plate 2, with the light inputting end face 21 set towards backlight 1 and the reflective end face relative with light inputting end face 21
22；And
Reflecting component 3, the reflective end face 22 for being bonded and fixed to light guide plate 2 by rubberised layer 4 is set.
It is appreciated that the backlight module is applied to side entering type module, above-mentioned light inputting end face 21 is light guide plate 2 towards backlight
1 one side for setting, reflective end face 22 is the another side of the light guide plate 2 relative with the side；In the present embodiment, backlight 1
It is the lamp bar (Light bar) set parallel to the light inputting end face 21 of light guide plate 2.In addition, in the present embodiment, rubberised layer 4 is by liquid
State gluing is constituted, and certainly, in other embodiment, rubberised layer 4 can also be made up of paste gluing；It is appreciated that the thickness of rubberised layer 4
It is h to spend, and the thickness that prior art fixes the double faced adhesive tape that reflecting component is used is h '；Obvious, thickness of the rubberised layer 4 than double faced adhesive tape
Thin, then the upside of reflective end face 22 height in light guide plate 2 is certain and in the case of being made full use of, and the thickness h of rubberised layer 4 is small
In the thickness h of double faced adhesive tape ', accordingly, the thickness of the present embodiment reflecting component 3 is greater than the thickness of reflecting component in the prior art, from
And obtain more preferable reflecting effect.
Technical solutions of the utility model by between reflecting component 3 and the reflective end face 22 of light guide plate 2 set rubberised layer 4,
So that reflecting component 3 to be close to be fixed on the reflective end face 22 of light guide plate 2, in this way, fixing anti-by double faced adhesive tape compared to prior art
The mode of light part, the utility model can reserve bigger installing space at reflective end face 22, for installing bigger anti-of thickness
Light part 3, so as to strengthen the reflecting effect of reflecting component 3, is utilized the more light of backlight 1, improves the light efficiency profit of light guide plate 2
With rate.
Further, the span of the thickness h of rubberised layer 4 is：0.01mm~0.03mm.It is appreciated that h is too small, instead
Bonding force between photosphere 31 and reflective end face 22 is smaller, and after backlight module long-term use, connection easily loosens, so that reflecting component
3 depart from from the reflective end face 22 of light guide plate 2；H is excessive, and the setting height(from bottom) of reflecting component 3 is reduced to a certain extent, so that weakening
The reflecting effect of reflecting component 3.
Further, multiple first light-reflecting particles 41 are provided with rubberised layer 4, the first light-reflecting particles 41 are used to strengthen rubberised layer
4 reflection action.It is appreciated that being arranged such, diffusing reflection effect of light when being propagated in rubberised layer 4 can be strengthened, entered in light
Weaker reflection is carried out before reflecting component 3, is slowed down light direct irradiation reflecting component 3 and is formed the bright line that the effect reflection of drastically high light causes and ask
Topic.
Further, the cause not of uniform size of multiple first light-reflecting particles 41.It is appreciated that being arranged such, light irradiation is each
Reflection case after first light-reflecting particles 41 is different, makes the reflection direction after the first light-reflecting particles of light irradiation 41 more various,
Increase the order of reflection between light the first light-reflecting particles 41 of multiple, strengthen the diffusing reflection of light.
Further, reference picture 2, the scope of the value of the diameter of the first light-reflecting particles 41 is：10 μm~50 μm.Can manage
Solution, the timing of 4 thickness of rubberised layer one, the diameter of the first light-reflecting particles 41 is excessive, the first light-reflecting particles 41 that the interior energy of rubberised layer 4 is set
Quantity it is fewer, occur that irreflexive number of times is fewer, the reflecting effect of the first light-reflecting particles 41 is weaker；First light-reflecting particles 41
Diameter is too small, and the probability that illumination is mapped to the first light-reflecting particles 41 is small, reduces diffusing reflection number of times, the first light-reflecting particles 41 it is reflective
Effect is weaker.
Further, the first light-reflecting particles 41 are hollow-particle.Specifically, rubberised layer 4 is applied and is located at the reflective of light guide plate 2
When on end face 22, the air gap can be formed in rubberised layer 4, the air gap forms above-mentioned hollow-particle.It should be noted that originally setting
Meter not limited to this, first light-reflecting particles 41 or the barium sulfate particles being filled in rubberised layer 4.
Further, referring to Figures 1 and 2, reflecting component 3 includes the reflector layer 31 and the reflective basic unit 32 that are mutually stacked, instead
The surface away from reflective basic unit 32 of photosphere 31 is adhesively fixed by rubberised layer 4 with the reflective end face 22 of light guide plate 2.Can manage
Solution, reflector layer 31 is the core texture of reflecting component 3, for carrying out strong reflection to incident light, so that light is returned in light guide plate 2；
And the reflective one side of basic unit 32 plays a protective role to reflector layer 31, prevent it to be subject to the external world to collide with, on the other hand can also have
Certain reflection action, to strengthen the reflecting effect of reflecting component 3.In the present embodiment, reflector layer 31 and reflective basic unit 32 are all by PET
(PET) material is made, and certainly, in other embodiment, reflector layer 31 also can be by other resin material systems
Into reflective basic unit 32 can also be made up of makrolon (PC) or polystyrene plastics (PS) material.
Further, multiple second light-reflecting particles 311 are provided with reflector layer 31, the second light-reflecting particles 311 are used to strengthen anti-
The reflection action of photosphere 31.In the present embodiment, the second light-reflecting particles 311 are the multiple hollow-particles being filled in reflector layer 31,
It is appreciated that being arranged such, the light of hollow-particle is irradiated to, it may occur that diffusing reflection, and returned in light guide plate 2, realize
The reflecting effect of reflector layer 31.It should be noted that the design not limited to this, in other embodiments, second light-reflecting particles
311 are alternatively silicon dioxide granule or TiO 2 particles.
The utility model also proposes a kind of display device, the display device include backlight module, the backlight module it is specific
Structure employs whole technical schemes of above-mentioned all embodiments due to this display device with reference to above-described embodiment, therefore at least
All beneficial effects that technical scheme with above-described embodiment is brought, this is no longer going to repeat them.
