Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] A high-barrier polyester film for quantum dot film, comprising a resin material body, characterized in that: quantum dots are dispersed on the resin material body, and a quantum dot light-emitting layer 1 is formed, and the quantum dot light-emitting layer 1 is above and the bottom are all wrapped with high barrier polyester film 2.

[0031] The polyester film base material is polyethylene terephthalate, and a double extruder and a coat hanger die are used to obtain a film with an ABA three-layer structure, and the specific B 100% film-grade glossy polyester chips are used for the first layer, and 70%-90% film-grade glossy polyester chips and 10%-30% silica functional masterbatch are used for the two surface layers A.

[0032] The thickness of the polyester film substrate is 12-75 μm.

[0033] The formula of the water-based high barrier coating solution is as follo...

Abstract

The invention relates to a quantum dot film which is suitable for the fields of quantum dot televisions and organic electric laser display, and especially relates to a high-barrier polyester film for a quantum dot film, and a preparation method thereof. The high-barrier polyester film comprises a resin material body and is characterized in that quantum dots are dispersed on the resin material body, a quantum dot light-emitting layer is formed, and the upper portion and the lower portion of the quantum dot light-emitting layer are wrapped with high-barrier polyester films. Compared with the prior art, the quantum dot film has the advantages that the quantum dot film serves as a brand new nanometer material with unique light characteristics, high-energy blue light can be accurately and efficiently converted into red light and green light, quantum dots can form a layer of film on LED backlight of an LCD display screen, full-spectrum light can be emitted through irradiation of a blue LED, and by finely adjusting the backlight, the color gamut performance can be greatly improved, and the color is brighter. Compared with a traditional LCD, the color gamut of the quantum dot display screen can reach 110%.

Description

technical field [0001] The invention relates to a quantum dot film suitable for the fields of quantum dot TV and organic electric laser display, in particular to a high-barrier polyester film for a quantum dot film and a preparation method thereof. Background technique [0002] Most of the optical-grade water-oxygen barrier films used in the quantum dot films in the existing technical solutions are imported materials, and ordinary domestic optical films cannot meet the technical requirements. [0003] Quantum dot technology enables LCD (liquid crystal display) to be realized in a wide range of colors. It is an ideal technology for picture information above 4K level. It is regarded as the commanding height of global display technology and also regarded as a display technology revolution affecting the world. It can greatly improve the color reproducibility, chromaticity, and overall brightness of the screen image. Compared with the early LCD, the color display ability is 50% h...
