Selective wave point position type anti-blue-ray thin film

Abstract

The invention relates to a selective wave point position type anti-blue-ray thin film. The anti-blue-ray thin film comprises an anti-wear layer, anti-blue-ray layers, a substrate layer and a mountingadhesive layer; the anti-wear layer is made of wear-resistant polyurethane; the substrate layer is selected from one of cellulose triacetate and polyethylene glycol terephthalate; each anti-blue-ray layer is selected from three or above of nano-scale silicon dioxide, nano-scale titanium dioxide, nano-scale cerium oxide, nano-scale tin oxide, nano-scale platinum, nano-scale palladium and nano-scalemagnesium fluoride; and the multiple anti-blue-ray layers can be arranged according to needs and can shield blue rays with narrow bandwidth (less than or equal to 5 nm) and with the wavelength at thewave point positions of 411 nm, 430 nm, 440 nm and 450 nm and blue rays with the wavelength of 460-480 nm. The anti-blue-ray thin film has the advantages that (1) a proper blue ray shielding scheme is provided for users of different ages and different using occasions; and (2) the harmful blue rays are efficiently shielded, and meanwhile, the influence on color vision of human eyes is weakened tothe maximum degree, in addition, excessive shielding cannot be caused, and the protection principle of minimization is met.

Description

technical field [0001] The invention relates to the technical field of thin film display, in particular to a selective wave point anti-blue light film. Background technique [0002] With the development of science and technology, electronic screen products, LED light sources, etc. have become an indispensable part of people's lives. However, while they bring us convenience, they also have potential hazards - the large amount of high-energy short-wave blue light they emit can penetrate the lens and reach the retina, causing chronic retinal damage. [0003] Blue light is the light of 400-500nm in visible light, of which the short-wave blue light of 400-460nm is particularly damaging to the retina. The study found that 411nm short-wave blue light has a strong killing effect on cell mitochondria, especially retinal ganglion cell mitochondria; A2E is the most sensitive when stimulated by 430nm blue light, and will generate a large number of free radical ions to stimulate the pho...
