Abstract

The invention relates to the technical field of multi-layer coating films of glass substrates, in particular to a mobile phone faceplate multi-layer coating film layer and a preparation method thereof. According to the technology for preparing the high-transmittance and abrasion-resistant multi-layer film on a glass substrate, the glass substrate, a magnesium oxide polycrystal seed layer, a high-hardness abrasion-resistant aluminum oxide coating film layer and a titanium oxide/aluminum oxide laminated transmittance enhanced layer are specifically included. According to the mobile phone faceplate multi-layer coating film layer and the preparation method thereof, (1) the metal organic chemical vapor deposition (MOCVD) technology is adopted so that large-area uniform film forming can be achieved; (2) through the design of a polycrystal buffer layer, the high-hardness aluminum oxide coating film of a microcrystal-amorphous mixed structure is grown in an extending mode at a low film forming temperature; and (3) the transmittance is improved through the aluminum oxide/titanium oxide/aluminum oxide laminated layer.

Description

technical field [0001] The invention relates to the technical field of multilayer coating of glass substrates, and more specifically, relates to a multilayer coating layer of a mobile phone panel and a preparation method thereof. Background technique [0002] With the development of display and mobile terminals, it is urgent to seek glass coating technology with low cost, high wear resistance and scratch resistance, and high transmission characteristics to meet the needs of mobile terminal products such as smart phone panels. Under the above background, coating glass panels with high hardness and high transmittance will be an effective way to realize high scratch resistance, high transmittance, and low-cost smartphone panels. At present, the diamond-like carbon film (DLC: Diamond Like Carbon) is widely researched and applied as a high-hardness coating technology, which has the advantages of diamond carbon sp3 hybrid orbital, high hardness, chemical inertness, and low frictio...
