Abstract

The invention discloses a conduction film of second face of electrochromism inside rear-view mirror, wherein the conduction film contains high refractive index material as priming coat and ITO film as the second face of conduction material; or the conduction film contains double-layer high refractive index material as priming coat and ITO film as the second face of conduction material; or the conduction film is composed of three-layer high refractive index material as priming coat and ITO film as the second face of conduction material. The high refractive index is combination of SiN or SiC and Eu2O3 or WO3. The multiple high refractive index layers and film thickness of the invention guarantee passivation efficiency of silicon wafer surface, at the same time, the two-layer high refractive index thin has effect of PID resistance, and the design film has good anti-reflection effect, which increases light interception rate of the surface of silicon wafer.

Description

Technical field [0001] The invention relates to an automobile electrochromic inner rearview mirror, in particular to a conductive film on the second surface of an automobile electrochromic inner rearview mirror and a production method thereof. Background technique [0002] Ordinary car rearview mirrors only serve as a mirror reflection function, without anti-glare function. When driving at night, the headlights of subsequent vehicles reflect too much, which will cause the driver to dizzy briefly and cause frequent car accidents. The demand for driving safety has given birth to the emergence of semi-reflective and semi-transparent smart rearview mirrors that focus on driving records, reversing radar, and the intelligent concept of car networking. At present, the semi-reflective semi-transparent silver mirrors and blue mirrors produced by various dielectric films that are popular on the market are used in semi-reflective semi-transparent smart rearview mirror products. The most i...
