Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the relatively high surface reflectivity of the zinc nitride film prepared by the magnetron sputtering process in the prior art, and to prepare the light-shielding layer in the BM area of ​​the touch screen cover plate by screen printing using black ink. At this time, the coating yield rate is low, the production cost is high, and the production efficiency is low. When the obtained product is bonded with a liquid crystal display, it is easy to generate bubbles and cannot achieve perfect bonding. A method for preparing a touch screen cover plate and a film is provided. ,application

Abstract

The invention discloses a touch screen cover plate and a preparation method and application of a film. The preparation method of the touch screen cover plate film comprises the following steps that (1) oxygen serves as reaction gas, argon serves as sputtering gas, a silicon target is reacted on a resin substrate, and a silicon oxide film is formed through sputtering; (2) nitrogen serves as sputtering gas and reaction gas, a zinc target is reacted on the resin substrate coated with the silicon oxide film, and a zinc nitride film is formed through sputtering; and (3) nitrogen serves as reaction gas, argon serves as sputtering gas, a silicon target is reacted on the resin substrate coated with the zinc nitride film, and a silicon nitride film is formed through sputtering, so that the touch screen cover plate film is obtained. The touch screen cover plate film is high in production efficiency, high in film coating yield, low in production cost, high in surface hardness, high in scratching resistance and abrasion resistance, high in surface energy and capable of being attached to a liquid crystal displayer effectively, eliminating the segment difference effect and being applied to a resin substrate touch screen to manufacture the touch screen cover plate.

Description

technical field [0001] The invention relates to a preparation method and application of a touch screen cover plate and a film. Background technique [0002] With the advancement of science and technology and the development of smart devices, the demand for touch screens as the main window of human-computer interaction has become more and more vigorous. In recent years, the annual shipments have shown explosive growth. With the technological innovation and fierce The competition in the world has put forward higher requirements for the production technology and cost of the touch screen. As the main functional component of the touch screen, the optical cover of the touch screen has high requirements on the production technology and production cost of the optical cover area of ​​the BM area (Black Matrix). [0003] The light-shielding layer in the BM area of ​​the traditional touch screen cover is mainly realized by the screen printing technology of black ink. However, the scr...
