49 results about "Smart film" patented technology

Smart film, also called Switchable film, is a product that is capable of adjusting light transmission between transparent and opaque using AC power. Due to moisture sensitivity, earlier versions of the film were used only to make smart glass by lamination on glass. With continual improvement in moisture resistance, the new (3rd) generation of the film can be directly installed on existing windows with special glue or self-adhesive. It combines many functions, such as light adjustment, UV and infrared blocking, advertising and security.
