Problems solved by technology

Although this technology can make fingerprints be easily wiped off, it has the following problems: 1. With the increase of the number of times of scrubbing, the silicone-based compound or fluorine-containing antifouling agent remaining on the hard coat surface will be less and less Until it disappears completely, it will eventually lose its anti-fingerprint function; 2. It is difficult to prevent fingerprint pollution formed by grease, water, salt, etc., and these fingerprints are obvious on the surface of the hard coating

Abstract

The invention discloses an anti-fingerprint transparent hardening film for a touch screen. The anti-fingerprint transparent hardening film comprises a transparent support body and a transparent hard coating arranged on the surface of the transparent support body, wherein particles with average particle size of 0.1-0.9mu m are distributed on the surface of the transparent hard coating, and bulges with height of 0.1-0.9mu m are formed on the surface of the transparent hard coating. According to the anti-fingerprint transparent hardening film, water and grease in fingerprints are dispersed by using the micro bulges on the surface of the hardening layer; and the anti-fingerprint transparent hardening film is remarkable in anti-fingerprint pollution effect, high in light transmittance and excellent in scratching resistance, and can be widely applied to the field of screen protection.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to an anti-fingerprint transparent cured film for a touch screen. Background technique [0002] With the popularity of tablet computers and large-screen smart phones, touch screens are widely used in various fields. However, in the process of using the touch screen, since the touch screen is often operated with hands, it is easy to stain or scratch the touch screen. Now a very common method is to paste a layer of ultraviolet (UV) cured hardening film on the outside of the touch screen to protect the screen. Although the hard coating of the hardened film has a high hardness and can play a protective role, it is easily stained by fingerprints. [0003] In order to solve the problem of fingerprint pollution, the known technology is to reduce the surface energy of the film by adding silicone or fluorine-containing antifouling agent to the hard coating, improve its hydrophobic and ole...
