Problems solved by technology

[0003] When the external surface of the flat-panel display reflects the surrounding glare or the glare generated inside enters the human eye, it is easy to cause glare and blur, hinder the clear display of the screen content, thereby causing visual fatigue and long-term damage to human vision; and the light source in the flat-panel display is unavoidable. The ground will produce high-energy short-wave ultraviolet light, purple light and blue light, and the light in these bands will damage the retina of the human eye fundus to varying degrees

Abstract

The invention relates to a blue-light-barrier anti-dazzle optical film and a preparation method therefor. The blue-light-barrier anti-dazzle optical film comprises a transparent substrate which is formed through laminating two layers of transparent films with the thickness of 20-200 microns, wherein a laminating interlayer is a composite adhesive layer, which contains an anti-ultraviolet agent and a blue and purple light barrier dye and has the thickness of 10-30 microns, one face of the transparent substrate is coated with an anti-dazzle and scratch-resistant coating layer with the thickness of 2-10 microns, the other face of the transparent substrate is coated with a pressure-sensitive adhesive, i.e., a binder with the thickness of 5-40 microns, and the surface of the pressure-sensitive adhesive is covered with a release film. The film material plays roles in preventing dazzle, cutting off blue light, reducing visual fatigue and protecting vision and further has the function of protecting a LCD screen from scratch.

Description

technical field [0001] The invention relates to a hard coating film used for protecting the surfaces of various displays and touch screens. Background technique [0002] In recent years, various new flat panel display (LCD, OLED, EL, PDP) technologies and products have developed rapidly, making flat panel displays an indispensable part of electronic products in public life. [0003] When the external surface of the flat-panel display reflects the surrounding glare or the glare generated inside enters the human eye, it is easy to cause glare and blur, hinder the clear display of the screen content, thereby causing visual fatigue and long-term damage to human vision; and the light source in the flat-panel display is unavoidable. The ground will produce high-energy short-wave ultraviolet light, purple light and blue light, and the light in these bands will damage the retina of the human eye fundus to varying degrees. Medical research has shown that ultraviolet light between 20...
