Switchable Transparent Glass can manage transparency instantly in response to user demand for seclusion, privacy or confidentiality without compromising light transmission. User just turns Switchable Transparent Glass "on" for transparent glass and "off" for opaque glass within one second by power switch. STG allows immediate switching from translucent to transparent.
STG is made of Switchable transparent Film(STF). STF is a light modulating material comprised of droplets of liquid crystal uniformly dispersed in a transparency or translucency, flexible plastic film.
STF operates on the principle of electrically controlled light scattering. They consist of liquid crystal droplets surrounded by polymer mixture sandwiched between two pieces of conducting film. When no electricity is applied, the liquid crystal droplets are randomly oriented, creating and opaque state. When electricity is applied, the liquid crystals aline parallel to the electric field and light passes through, creating a transparent state.
