Abstract
The utility model discloses a quantum barrier film of display screen is glued to quantum dot, including a light transmissivity plastic film through biaxial stretching, the first surface of light transmissivity plastic film has a silicon dioxide layer through vacuum sputtering technology complex, and the second surface of light transmissivity plastic film has a PVDC layer through the printing technology complex. The utility model discloses simple structure, it is with low costs, the utility model discloses a quantum barrier film has the fabulous oxygen nature that hinders and hinders moistly, satisfies the technical requirement that the display screen was glued to the quantum dot.
Description
Technical field
The utility model relates to quantum dot glue display screen technology field, especially relates to a kind of quantum Obstruct membrane of quantum dot glue display screen.
Background technology
Along with the development of electronic technology, LED display is popularized comprehensively, and LED display has obtained huge progress in brightness, color and visible angle etc., but still deposits larger difference between the color of LED display and realistic colour.In order to solve this technical problem, quantum dot glue display screen arises at the historic moment, quantum dot glue display screen has higher resolution ratio and more real color, colour gamut and saturation boost more than 100%, the color of quantum dot glue display screen is abundanter, bright-coloured and fine and smooth, picture is truer, and the quantum dot glue-line of quantum dot glue display screen is the surface of carrying one quantum Obstruct membrane, the two sides of quantum dot glue-line is compounded with a quantum Obstruct membrane respectively, quantum Obstruct membrane has the requirement of pole to gas air penetrability and moisture permeability, common quantum Obstruct membrane cannot meet the technical requirement of quantum dot glue display screen, therefore be necessary to be improved.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of quantum Obstruct membrane of quantum dot glue display screen, and its structure is simple, and cost is low, and its gas air penetrability and moisture permeability meet the technical requirement of quantum dot glue display screen.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of quantum Obstruct membrane of quantum dot glue display screen, comprise one through the light transmission plastic foil of biaxial tension, the first surface of light transmission plastic foil is compounded with a silicon dioxide layer by sputtering vacuum process, and the second surface of light transmission plastic foil is compounded with a PVDC layer by typography.
In further technical scheme, described light transmission plastic foil is selected and is made up and the PET film stretched to its longitudinal direction and horizontal direction by stretch processes of PET material.
In further technical scheme, the thickness of described light transmission plastic foil is 0.02 ~ 0.188mm.
In further technical scheme, the thickness of described silicon dioxide layer is 20 ~ 2000nm.
In further technical scheme, the thickness of described PVDC layer is 5 ~ 1000um.
Adopt after said structure, the utility model compared to the prior art advantageously: the utility model structure is simple, and cost is low, and quantum Obstruct membrane of the present utility model has fabulous oxygen barrier and resistance is moist, meets the technical requirement of quantum dot glue display screen.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure:
1, silicon dioxide layer 2, light transmission plastic foil 3, PVDC layer.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Quantum Obstruct membrane of the present utility model has fabulous oxygen barrier and resistance is moist.Test by moisture permeability testing standard JISK7219, moisture permeability is for being more than or equal to 10
-2.Test by gas penetration testing standard JIS7126-1, gas permeation rate is for being more than or equal to 10
-2.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
