Liquid crystal closed-loop controlled mirror systems

摘要: A rearview mirror system comprises an electrically controlled optical transmission plate disposed over a reflecting surface. The is selectively operable to any of number different states opaqueness between maximum light and opaqueness. the by electronic circuit which includes two sensors, one for sensing brightness incident from field view other ambient light. control operates cause on surface be closed loop regulated desired degree also correlated with conditions. manually adjustment provided observer set characteristic.
