The utility model relates to TV back light model setting technology field, in particular to a kind of Quantum Dot Glass light guide plate assembly and back
Optical mode group, display.
Background technique
Traditionally, LCD TV uses acrylic light guide plate, and thickness is generally 3-5mm, this is difficult designer
Television thickness is reduced again.Newest structure is using glass light guide plate, with ultra-violet curing pressure sensitive adhesive glass in the prior art
Light guide plate and reflector plate bond together, and just constitute light guide plate assembly.The optical property and mechanical performance of this component, are integrally wanted
Better than traditional acrylic light guide plate assembly.Due to the high-mechanical property of glass itself, the use of aluminium backboard can be cancelled, make liquid
Brilliant TV becomes thinner, most thin to be less than 5mm, reduces the thickness of television set 70% and 30% weight.
On available liquid crystal display, with it is in bright gay color degree require it is higher and higher, generally can use quantum film framework
Mode come improve chromaticity and improve efficiency.Current quantum film is upper and lower two PET (polyethylene terephthalate)
Film, the quantum dot that centre uniformly coats press.
As shown in Figure 1, existing quantum dot mould group includes: reflector plate 3, the light guide plate (LGP) 5 with optics site 4, by two
Quantum film 9, lower diffusion sheet 8 and other optical film materials made of PET film 6 and quantum dot 7 are opened, and each component is individually placed.
The shortcomings that existing quantum dot mould group, mainly has following: 1, discrete item is more, as traditional machine assembly, needs
A large amount of manpower；2, due to the presence of conventional aluminum backboard, mould group thickness can not reach the design of slimming；3, traditional quantum film is deposited
In edge fail area, edge indigo plant side phenomenon is presented on picture, additional cost need to be increased by eliminating this phenomenon.
Utility model content
To solve above-mentioned deficiency of the prior art, the utility model provide a kind of novel Quantum Dot Glass light guide plate
Component and backlight module, display achieve the effect that show color gamut value saturation to substitute quantum film.
The technical solution of the utility model is achieved in that
A kind of Quantum Dot Glass light guide plate assembly, including upper and lower two sheet glass；Lower thickness of glass 0.5mm-2mm, following table
It designs optics site and converts area source for linear light source in face；Upper thickness of glass 0.3mm-1mm, lower surface are coated with quantum dot
Layer；Upper and lower two sheet glass is fitted tightly over together, and bonding position edge is bonded by glass cement.
Optionally, the lower surface of the lower glass, the local optics dot density close to LED is smaller, further away from the ground of LED
Fang Guangxue dot density is bigger.
Optionally, in the upper surface of upper glass coating diffusion oxidant layer, light is spread and is atomized.
The utility model also proposed a kind of backlight module, including above-mentioned Quantum Dot Glass light guide plate assembly.
The utility model also proposed a kind of display, including above-mentioned backlight module.
The beneficial effects of the utility model are:
The quantum film that the Quantum Dot Glass light guide plate assembly of the utility model is formed instead of traditional PET, remains simultaneously
The property of light guide plate can carry out optics net-pont design, optimize the uniformity of picture, in the TV of the following ultrathin and superelevation colour gamut
It is of great significance in mould group.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is existing quantum dot light guide plate assembly structural schematic diagram；
Fig. 2 is the structural schematic diagram of the quantum dot light guide plate assembly of the utility model；
Fig. 3 is the structural schematic diagram of the backlight module of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model proposes a kind of Quantum Dot Glass light guide plate assemblies, as shown in Fig. 2, including upper and lower two sheet glass；
Lower 20 thickness 0.5mm-2mm of glass, linear light source is converted area source by lower surface design optics site 21, therefore lower glass has
There is optical light guiding plate characteristic.Upper 10 thickness 0.3mm-1mm of glass, lower surface are coated with quantum dot layer 30, and upper glass 10 is main
Play the role of protect quantum dot layer, correspondingly can the upper surface to upper glass carry out certain surface treatment, so that it is had expansion
The effect of astigmatism line, for example, spreading and being atomized by light, optimize optical frame, make in the upper surface of upper glass coating diffusion oxidant layer
It is more evenly soft.Upper and lower two sheet glass is fitted tightly over together, and bonding position edge is bonded by glass cement 40, and isolation is empty
Gas and water as long as the area of glass cement covers bonding position edge, such as are carried out within the scope of edge 0.5mm by glass cement
Bonding.
Glass after fitting has high mechanical strength, stress value, high durability and anti-scratch property, can replace quantum film,
Applied in blue-ray LED sidelight type backlight module.Fig. 3 is shown the Quantum Dot Glass light guide plate assembly application of the utility model
A specific embodiment in backlight assembly, the backlight module 100 include: liquid-crystalline glasses 70, diffusion sheet 80, brightening piece 90,
Quantum Dot Glass light guide plate assembly 1, reflector plate 50, auxiliary stand 65 and blue led 60, Quantum Dot Glass light guide plate assembly
The lower surface design of lower glass has site 21.
The lower surface of the lower glass, the local optics dot density close to LED is smaller, further away from the local optics of LED
Dot density is bigger, and by above-mentioned net-pont design, the light for issuing LED lamp bead propagates to entire picture, goes out picture uniformly
Light makes lower glass have the function that linear light source is converted to area source.
The Quantum Dot Glass light guide plate of the utility model, can be widely applied in the sidelight type backlight module of blue LED lamp,
Instead of the quantum film of traditional PET composition, while the property of light guide plate is remained, optics net-pont design can be carried out, optimizes picture
The uniformity in face makes TV mould group to ultrathin, the development of superelevation colour gamut.
The utility model also proposed a kind of backlight module, including previously described Quantum Dot Glass light guide plate.
The utility model also proposed a kind of display, including previously described backlight assembly.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
