Abstract

The invention provides a preparation method for a touch screen surface anti-fingerprint film. The method comprises: under argon gas atmosphere, adopting magnetron sputtering to form an anti-fingerprint film on the surface of a glass substrate, wherein a target material adopted by magnetron sputtering contains silica and a fluorine-containing organic compound. With the preparation method of the present invention, fingerprints can not be stuck on the prepared anti-fingerprint film, an anti-fouling effect is good, adhesion of the film on the surface of the substrate is strong, and the film is suitable for large size touch screens.

Description

technical field [0001] The invention relates to a preparation method of an anti-fingerprint film, in particular to a preparation method of an anti-fingerprint film used on the surface of a touch screen. Background technique [0002] With the development of the electronic industry, the application of touch screen is more and more extensive, from the initial small screen mobile phone, MP3, to the computer, ATM, medical treatment, industrial control equipment and monitor and TV set of large size screen now. Especially in the past two years, the introduction of tablet computers has driven the development of touch screen technology, which is also being gradually applied to other portable electronic products. As the scale of the mobile phone market continues to increase, and the requirements for smart and convenient mobile phones are getting higher and higher, touch screens, as the most friendly human-machine interface, will be more and more popular in mobile phones. While the to...
