preparation example Construction

[0063] The preparation method of the blue light cutoff and visible light antireflection bifunctional coated glass comprises the following steps:

[0064] The glass substrate to be coated is cleaned and dried with deionized water to obtain a clean sample; the clean glass is placed in a vacuum box for sputtering coating, and the glass surface is treated with a plasma formed by a voltage of 500-1000V under normal pressure nitrogen. ; Then pump the air pressure of the vacuum box to 3.5~8.5×10 -4 Pa. The thickness of the blue cut-off film is 110nm-326nm, and the thickness of the visible light anti-reflection film is 170nm-330nm.

Abstract

The invention relates to coated glass with blue-light cutoff and visible light anti-reflexion dual functions and a preparation method therefor. According to the coated glass, a film layer structure consists of a blue-light cutoff film, glass and anti-reflection film sequentially, and coating is carried out by adopting a magnetron sputtering method; the transmittance is increased by 1.5% to 5.5% compared with that of uncoated sheet glass in the spectrum wavelength range of 380nm to 780nm; the blue-light cutoff rate is increased by 40% to 75%, and the ultraviolet ray cutoff rate is 100%; the pencil hardness of a film layer is 8.0H; the obtained coated glass can be applied to the fields of electronic display panels, mobile phone encapsulation glass cover plates, LED (Light Emitting Diode) lighting lampshades, show windows, eyeglass frames, locomotive and steamboat window glass and the like; and through observing through observation window glass, images are free from glare and are clearer, the fatigue of human eyes is reduced, and the injury to the human eyes is prevented.

Description

technical field [0001] The invention belongs to the fields of display devices, instrument packaging, protective glass cover plates, LED lamps and lanterns glass covers, shop windows, and locomotive and ship window glass, and particularly relates to a blue light cut-off and visible light anti-reflection dual-function coated glass and preparation thereof method. Background technique [0002] In the fields of electronic display device encapsulation, protective glass cover, shop window, LED lamp glass cover, etc., where glass is used as a window, blue light can transmit ordinary glass, causing damage to the observer's eyes. According to the results of medical research, in addition to ultraviolet rays that are harmful to the eyes, there is also a high-energy violet / blue light that has a greater lethality to the macular part of the retina of the eye. Blue light has a short wavelength and high energy. A large amount of blue light is retained in artificial light sources such as LED...
