Micro-structure is added in the incidence surface of plate, so that the injection of its micro-structure and the matter of bad control very in light guide plate manufacturing process
Amount, and this manufacturing process must improve the manufacturing cost of mold.
Summary of the invention
To achieve the above object, it the present invention provides a kind of quantum dot adhesive tape, takes following technical scheme: including: one
Body layer, as made by a transparent plastic material；One adhesion layer, positioned at the side of the body layer；An and at least quantum dot
Material is dispersed in the body layer；Wherein an at least quanta point material includes red quantum dot material or green amount
Son point material.
The present invention also proposes a kind of quantum dot backlight module, includes: a light guide plate；An at least light emitting device, is set to
The side of the light guide plate；And a quantum dot adhesive tape, it is attached on the side of the light guide plate.The wherein quantum dot adhesive tape
Include: a body layer, is made of a transparent plastic material；One adhesion layer, positioned at the side of the body layer；An at least quantum dot
Material is dispersed in the body layer；And a plurality of micro-structures, set on the body layer relative to the another of the adhesion layer
Side.Wherein, an at least quanta point material includes red quantum dot material or green quanta point material.Whereby, from luminous
The quanta point material in light excitation quantum dispensing band that device issues, may make red wide with the narrow wave of green on spectrogram
And make the range in colour gamut bigger.
Above to summary of the invention, it is therefore intended that it is of the invention it is several towards and technical characteristic make a basic explanation.
Invention summary is not to detailed statement of the invention, therefore its purpose is not enumerating key or important set of the invention especially
Several concepts of the invention only are presented in a manner of concise nor being used to define the scope of the present invention in part.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts it is all its
His embodiment, shall fall within the protection scope of the present invention.
To will appreciate that technical characteristic and practical effect of the invention, and it can implement according to the content of specification, hereby into one
Step is with preferred embodiment as indicated in the drawings, and detailed description is as follows:
It is quantum dot adhesive tape schematic diagram of the invention firstly, please referring to shown in figure one.The present invention proposes a kind of quantum dot
Adhesive tape 10 includes: a body layer 12, as made by a transparent plastic material；One adhesion layer 14, positioned at the body layer 12
Side；And an at least quanta point material 16, it is dispersed in the body layer 14；A wherein at least quanta point material 16
Including red quantum dot material or green quanta point material.
In the present embodiment, the material of the transparent plastic material is ethylene terephthalate (PET), due to PET material
Matter has preferable toughness and pliability, while having the advantages such as frivolous quality, acid and alkali-resistance and resistance to water oxygen, and be usually used in optics
The optical articles such as disc, polaroid；Therefore, ethylene terephthalate (PET) is quantum dot adhesive tape body layer 12 of the present invention
Best applications material.In other possible embodiments, the transparent plastic material can also be polycarbonate (PC), polychlorostyrene second
Alkene (PVC) or polymethyl methacrylate (PMMA) etc. are usually used in the polymer of adhesive tape material, and the present invention should not be as limit.
Wherein, the thickness of the body layer 12 is between 10 microns (μm) to 1000 microns；Preferable thickness is to be situated between
Between 50 microns to 200 microns；Optimal thickness is 100 microns.
