Title:
GLASS PLATING LAYER STRUCTURE, FINGERPRINT DETECTION APPARATUS, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2017/067078
Kind Code:
A1
Abstract:
Provided are a glass plating layer structure, a fingerprint detection apparatus, and a mobile terminal. The glass plating layer structure comprises a glass substrate; a titanium oxynitride plated film layer and a silicon oxynitride plated film layer are downwardly arranged in alternation on the lower surface of the glass substrate; in the molecular formulas of the titanium oxynitride and silicon oxynitride in the plated film layers, the ratio of nitrogen to oxygen is the same: the range of values is 0.4-1.5:1. a titanium oxynitride plated film layer and a silicon oxynitride plated film layer are plated on the lower surface of the glass substrate, and the ratio of nitrogen to oxygen in the plating layer compounds is the same: the values are within the range of 0.4:1 to 1.5:1; thus given that insulation is ensured, a glass plating layer structure having a glossy effect is achieved, and the impact of the thickness of the plating layer on fingerprint detection is kept to within a very small range.
