preparation example Construction

[0035] Preparation of the anti-reflection layer: the substrate is placed under vacuum conditions, and multiple high-refractive-index layers and multiple low-refractive-index layers are formed on the surface of the substrate by means of evaporation or sputtering. layer and a plurality of low refractive index layers are stacked alternately to form an anti-reflection layer to obtain a cover plate precursor;

[0036] Preparation of the anti-fingerprint layer: the cover plate precursor is placed under vacuum conditions, nitrogen and argon are introduced as the reaction atmosphere, titanium and polytetrafluoroethylene are used as mixed targets, and the cover plate is deposited on the cover by magnetron sputtering. An anti-fingerprint layer is formed on the plate precursor, and in the mixed target material, the molar ratio of titanium and polytetrafluoroethylene is 0.1-0.3:1.

[0037] The coating structure of the cover plate of the mobile phone camera as described above is prepared by ...

Embodiment 1

[0065] This embodiment is used to illustrate the coating structure and preparation method of the mobile phone camera cover plate disclosed by the present invention, including the following steps:

[0066] Step 1: Place the substrate in acetone and ultrasonically clean it for 10 minutes; then place the substrate in deionized water and ultrasonically clean it for 10 minutes; take out the substrate and dry it to remove surface moisture;

[0067] Step 2: Ink printing is performed on the light-shielding area of ​​the substrate by silk screen printing to form an ink layer, and ink printing is not performed on the light-transmitting area of ​​the substrate, and the printed substrate is placed in a high-temperature oven for curing;

[0068] Step 3: Place the substrate under vacuum conditions, turn on the ion source to bombard and clean the surface of the substrate, and the cleaning time is 5 minutes;

[0069] Turn on the ion source to bombard the Ti target, and at the same time pass t...

Abstract

In order to overcome the problem of insufficient wear resistance in the existing mobile phone camera cover plate, the present invention provides a mobile phone camera cover plate coating structure, including a substrate, an anti-reflection layer and an anti-fingerprint layer. The light-transmitting area, the anti-reflection layer is located on both sides of the light-transmitting area, the anti-fingerprint layer is located on one side of the substrate, and one of the anti-reflection layers is located on the anti-fingerprint layer and the anti-fingerprint layer. Between the substrates, the anti-fingerprint layer is a mixed sputtering layer of titanium nitride and polytetrafluoroethylene, and the molar ratio of titanium nitride and polytetrafluoroethylene in the anti-fingerprint layer is 0.1˜0.3:1. The coating structure of the cover plate of the mobile phone camera provided by the invention has good anti-friction performance, and can still maintain its anti-fingerprint property under continuous friction.

Description

technical field [0001] The invention belongs to the technical field of vacuum coating structures, and in particular relates to a coating structure for a mobile phone camera cover plate. Background technique [0002] Along with the miniaturization and sophistication of consumer electronic products such as digital cameras, mobile phones, PDAs, and even video game consoles, such electronic products are usually equipped with optical image capture components, and the optical components installed in them are Image capture components will require higher performance. [0003] In the existing design of electronic products, in order to protect the camera of the electronic product, a transparent cover is usually arranged at the position of the camera. The transparent cover can not only ensure the image capture of the camera, but also play a protective role. [0004] In order to ensure the light transmittance and oil resistance of the transparent cover, an anti-reflection layer and an ...
