Description
Technical field
The utility model is related to field of backlights, more particularly to a kind of backlight and liquid crystal display module.
Background technology
The raising required with user display effect is, it is necessary to improve the color gamut value of liquid crystal display module, and improve backlight
The white light color gamut value in source is a kind of effective way for the color gamut value for improving liquid crystal display module.At present, the white light of backlight is to use
The white light that the blue ray that blue LED die is sent is produced after yellow fluorescent powder, the color gamut value of this white light is than relatively low.
In the prior art, in order to improve the color gamut value of backlight, light emitting source excitation quantum point is used typically in backlight
The mode of film obtains the white light of high color gamut value, but the cross-section structure of quantum dot film is generally the amount that two PET films clip centre
Son point material layer, after use is cut, exposed quanta point material layer and air, moisture on the edge of quantum dot film, when
Between it is long can by oxidations such as air, steam ageing failure, cause the fringe region of backlight partially blue.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight and liquid crystal display module.Should
Quanta point material is directly mixed into formation quantum dot light guide plate in light guide plate by backlight, can not only improve the colour gamut of backlight
Value, and quanta point material contact with air, steam etc. can be completely cut off using light guide panel material, prevent quanta point material by oxygen
Change and ageing failure occur.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including framework and the quantum dot light guide plate being arranged in the framework, the quantum dot light guide plate
Incidence surface be provided with light emitting source.
Further, the quantum dot light guide plate includes red quanta point material and green quanta point material.
Further, it is provided with an at least optical film on the exiting surface of the quantum dot light guide plate.
Further, the side of the quantum dot light guide plate away from exiting surface is provided with reflector plate.
Further, it is provided with anti-dazzling screen on the framework.
Further, the light emitting source is white light LEDs or blue-ray LED.
A kind of liquid crystal display module, including above-mentioned backlight.
The utility model has the advantages that：Quanta point material is directly mixed into forming amount in light guide plate by the backlight
Son point light guide plate, can not only improve the color gamut value of backlight, and can using light guide panel material isolation quanta point material and
The contact of air, steam etc., prevents quanta point material to be oxidized and ageing failure occur.
Brief description of the drawings

The one side of light source can be white, silver color or other colors.
Preferably, the light emitting source 4 is white light LEDs or blue-ray LED, according to white light LEDs, then the white light LEDs
Interior blue-light LED chip excites yellow fluorescent powder formation white light, and some blue light in white light continues to excite the quantum dot to lead
Quanta point material in tabula rasa 2, to lift the color gamut value of white light；Then it is that the blue-ray LED is sent according to blue-ray LED
Blue light directly excites the quanta point material in the quantum dot light guide plate 2, forms high colour gamut white light.
The framework 1 can only have glue frame 11 or only metal frame 12, can also use metal frame 12 such as the present embodiment
With the phase clamping of glue frame 11 composition；The light emitting source 4 is set in assist side 41, and the wiring board 41 can be PCB or FPC；
The wiring board 41 is pasted onto on the medial surface of the side of framework 1, and the light emitting source 4 is luminous using top, certainly, the circuit
Plate 41 can also be pasted onto on the front of the quantum dot light guide plate 2 and framework 1, and the light emitting source 4 is lighted using side.
As the further optimization of the technical program, its excess-three side of the quantum dot light guide plate 2 in addition to incidence surface
Matcoveredn can be set on face, quanta point material on side and air further to completely cut off the quantum dot light guide plate 2,
Steam etc., the protective layer can coat the coating that formation or transparent material layer are dried after transparent adhesive tape.
Embodiment two
