PrivacyWall is a revolutionary decorative and technological on/off LED film. This special film creates privacy “on demand” and is suitable for use in various spaces such as offices, schools, banks, hospitals, apartments, and other sectors. It consists of a polymer matrix of liquid crystals, enclosed between two layers of polyester film coated with electro-conductive tin oxide, and is equipped with wiring connected to a copper conductive strip (called a bus-bar) along the edge. The wiring is connected to a step-down transformer that provides power to activate the “on” (transparent) or “off” (opaque) state.
