Smart glass or switchable glass (also known as intelligent glass, privacy glass, LC dimmable glass, smart windows or switchable windows in those applications) is a glass or glazing whose light transmission properties are altered when voltage, light or heat is applied. Generally, the glass changes from translucent to transparent, changing from blocking some (or all) wavelengths of light to letting light pass through.
Smart glass technologies: include electrochromic, photochromic, thermochromic, suspended-particle, micro-blind and polymer-dispersed liquid-crystal devices.
The smart glass is sandwiched the PDLC film between two panels of glasses, a new optoelectronic product comes out after high temperature and high pressure agglutination. As the PDLC film is opaque when powder off, transparent when powder on, the smart glass can not only be normal glass, but also plays as electrically controlled curtain to protect privacy and provide you comfortable & green life.
