What is smart glass? How does it work?

Smart glass, or switchable privacy glass, is a safety glass with a switchable opaque and transparent effect. It compounds the liquid crystal interlay into the middle of two layers of glass through high temperature and high-pressure processing. Thus, this photoelectric glass product has both characteristics of safety glass and electronically controlled curtains.
