Smart glass is a type of glass that can change its properties based on external stimuli such as heat, light, or electricity. There are different types of smart glass available, including PDLC (Polymer Dispersed Liquid Crystal) film and LED glass.

PDLC film is a type of smart film that uses a polymer dispersed liquid crystal technology. It consists of a thin layer of liquid crystals dispersed in a polymer matrix, sandwiched between two sheets of glass or plastic. When an electrical current is applied to the film, the liquid crystals align and the film becomes transparent.

LED glass is a type of smart glass that uses LED lights to change its appearance. It consists of a layer of glass or acrylic with embedded LEDs and a power supply.
