Liquid crystal glass is a type of smart glass that can change its transparency when an electric current is applied. It contains liquid crystals sandwiched between two layers of glass, allowing it to switch from clear to opaque. This technology is often used in windows, partitions, and displays to control light and privacy. When the electric current is turned off, the liquid crystals return to their original state, making the glass opaque. Liquid crystal glass is popular in modern architecture and design, providing both aesthetic appeal and functional benefits, such as energy efficiency and enhanced privacy in spaces like offices and homes.
