preparation example Construction

[0049] In a specific example, see the attached image 3 , the preparation method of bactericidal coating 1 comprises:

[0050] A1: Using magnetron sputtering vacuum coating equipment, TiO2 Sintered material and SiO 2 The sintered materials are installed on different cathode targets respectively;

[0051] A2: The glass substrate of the anti-glare treatment layer is etched with TiO in a vacuum chamber 2 Coating, mixing 0.1%-5% N in the working gas argon during coating 2 , up to TiO 2 The film thickness reaches 10nm-50nm, TiO 2 Coating completed;

[0052] A3: TiO will be plated 2 The glass substrate of the film layer is then subjected to SiO 2 coating, up to SiO 2 The thickness of the film layer reaches 5nm-20nm, SiO 2 After the coating is completed, a bactericidal coating is obtained.

[0053] Specifically, the light transmittance of the anti-blue light coating 4 to the wavelength range of 380-450nm is less than 50%, and the light transmittance of the anti-blue light c...

Embodiment 1

[0061] The anti-blue light sterilization and anti-glare protection sheet used for the display screen in this embodiment adopts the above-mentioned figure 1 In the layer structure shown, the transparent substrate is made of soda-lime glass, and the etching process of the anti-glare treatment layer is as follows:

[0062] Step 1: Attach a layer of adhesive protective film on the other side of the transparent substrate;

Abstract

The invention discloses an anti-blue-ray sterilization anti-glare protection sheet for a display screen. The anti-blue-ray sterilization anti-glare protection sheet comprises a transparent substrate,an anti-dazzle treatment layer, a sterilization plating layer, an anti-blue-ray plating layer and an adhesion layer, wherein the anti-dazzle treatment layer is etched on the surface of one side of thetransparent substrate; the sterilization plating layer is arranged on the surface of the anti-dazzle treatment layer; the anti-blue-ray plating layer is arranged on the surface of the other side of the transparent substrate; and the adhesion layer is arranged on the surface of the anti-blue-light plating layer. The protection sheet can be attached to the surface of the display screen through theadhesion layer. High-energy blue rays can be effectively blocked through the arrangement of the anti-blue-ray plating layer. Meanwhile, the sterilization plating layer and the anti-dazzle treatment layer are additionally arranged, the sterilization and anti-dazzle functions are further achieved on the basis of the anti-blue-light function, the functions are more complete, the protection effect onthe human body is better, and the use requirements of people for a multi-protection-function protection film can be better met.

Description

technical field [0001] The invention relates to the technical field of vacuum coating and eye protection protective film, and more specifically relates to an anti-blue light sterilization anti-glare protective sheet for display screens. Background technique [0002] At present, with the continuous advancement of science and technology, more and more smart products have entered people's lives, such as smart phones, tablet computers and other smart electronic products. As a medium for human-computer interaction, display screens are indispensable for these electronic products. Part, the display screen display pattern or document is composed of three primary colors through different energies, and the blue light component (430-440nm wavelength range) in the three primary colors has a greater destructive effect on the macular area of ​​the human eye. At the same time, due to the touch screen Users need to touch the screen frequently to realize the operation, and a large number of ...
