Problems solved by technology

The hazards of blue light are mainly reflected in: (1) Harmful blue light has extremely high energy, which can penetrate the lens directly to the retina and cause the atrophy or even death of retinal pigment epithelial cells; (2) the wavelength of blue light is short, and the focus point falls in front of the retina, making the image unclear , easy to cause eye tension; (3) blue light can inhibit the secretion of melatonin, directly affecting sleep

Abstract

The invention provides a quantum dot film and a preparation method thereof. The quantum dot film includes: a first quantum dot packaging structure, which includes encapsulated red quantum dots and green quantum dots; and a second quantum dot packaging structure arranged on one side of the first quantum dot packaging structure, the second quantum dot packaging structure The structure includes a second encapsulation material and a plurality of quantum dot parts arranged at intervals in the second encapsulation material, and the gap between each quantum dot part allows light to directly irradiate from one side of the second quantum dot encapsulation structure to the other side, The quantum dot part includes a third encapsulation material and blue quantum dots dispersed in the third encapsulation material. The present invention reduces the harmful blue light and reduces the harm of the blue light by setting the quantum dot part that can convert the harmful blue light.

Description

technical field [0001] The invention relates to the technical field of quantum dot materials, in particular to a quantum dot film and a preparation method thereof. Background technique [0002] Quantum dots, also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. Because of the quantum confinement of quantum dots, the continuous energy band structure becomes a domain of separated energy levels with molecular characteristics, which can emit fluorescence after being stimulated by light. The half-peak width of the excitation spectrum of quantum dots is narrow, symmetrical and adjustable, the color of emitted light can be adjusted, the photochemical stability is high, and the fluorescence lifetime is long. Quantum dot materials have a wide range of applications in the fields of optoelectronics and materials. . [0003] At present, the red and green quantum dot film is used to emit red light and green light under the excitation of the blue light backl...
