Information
has gloss	eng: Smart film is a new kind of smart glass technology in which a special film can be directly and easily applied to glass. The film adjusts to light under electric pressure to switch between a transparent and a semi-opaque state. It also meets the double requirements of glass on penetrability and privacy protection - the lighting is good even when it is not transparent. It also insulates and reflects infared light, making one's room warm in winter and cool in summer, and therefore conserves energy. Smart film utilizes the opto-electrical functions of optical film by employing liquid crystal (PDLC) optics.
