Abstract:

By using infrared detection technology and optical switching characteristics of liquid crystal cell,a new path has been opened for the technology for the anti-glimpse door mirror.This paper outlines the structure and working principle of anti-glimpse door mirror,introduces the key technologies for the process design and circuit design.After final assembly and circuit debugging,results show that such anti-glimpse door mirror meets the requirement for practical application.

Key words: anti glimpse of the door mirror;liquid crystal cell;infrared detection;films
