Touch screen anti-reflection anti-fouling membrane

Abstract

The invention discloses a touch screen anti-reflection anti-fouling membrane, which comprises a screen base plate, and is characterized by further comprising a first and a second anti-reflection membranes and an anti-wear anti-fouling coating membrane, wherein the first and the second anti-reflection membranes are arranged in and outside the screen base plate, the anti-wear anti-fouling coating membrane is arranged on the second anti-reflection membrane. The touch screen anti-reflection anti-fouling membrane has the function to reduce visible light reflectance on the surface of a touch screen panel, and improves whole transmittance of a touch screen. An outer layer anti-wear anti-fouling coating membrane can effectively improve anti-wear performance of a screen, prevents the touch screen from being polluted by dirt, and improves definition of the screen. The touch screen anti-reflection anti-fouling membrane adopts dual-frequency ion source coating membranes, effectively improves efficiency of coating membranes, and reduces cost.

Description

technical field [0001] The invention relates to the technical field of touch screen coating, in particular to an antireflection and antifouling film for a touch screen. Background technique [0002] At present, mobile phone panels generally use transparent glass or plexiglass as panels, but glass panels are relatively fragile and easily stained, and are easily scratched by sharp objects or contaminated by oil, which affects the permeability and appearance. In order to increase the convenience of use, optical coating technology is generally used to coat a thin film on the surface of the screen panel. Optical coating refers to a film system that coats one or more layers of dielectric film, metal film, or a mixture of the two on optical components or independent substrates to change the characteristics of light wave transmission. It belongs to a new branch of traditional physical optics. Optical films can be used on the surface of digital electronic products such as mobile pho...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to protect the screen, users of touch-screen electronic products generally adopt the method of sticking a film, that is, sticking a layer of plastic film on the outer wall of the glass panel. The traditional plastic film is mainly divided into two types: high-permeability film and frosted film. High reliability, the screen display is relatively clear, but the texture is soft, it is easier to scratch, it needs to be replaced frequently, the economy is poor, and it is easy to be stained with fingerprints to affect the appearance; the surface of the frosted film is uniformly equipped with many small particles, and the frosted film can be more durable. It can solve the problem of fingerprint contamination, but its permeability is poor, which makes the screen display effect drop

To sum up, it is obvious that pasting traditional plastic films on the surface of touch screens of electronic products is less effective and less economical.
