Smart film, also called PDLC film or switchable film, offers instant privacy at the flick of a switch. When no voltage is applied, the smart film is opaque ( frosted state ); When voltage is applied, the film is transparent.

Self-adhesive smart film is a new type of functional film that adds an optical grade doubled-sided cling layer on one side of the normal smart film. Due to its excellent bending ability, it can be affixed on the existing flat glass or curved glass, providing a simple and cost effective alternative for users.

Heat resistant film maintains the high transparency features of the normal self-adhesive smart film when power on, and presents a mysterious, noble gray-black color when power off. Besides the excellent characteristics of the normal smart film, it also has a very good heat insulation effect that makes it an ideal material for building energy-saving reconstruction or design.

Smart glass, also called switchable glass or privacy glass, is a new building decoration material that combines the smart film with glass. The laminated smart glass is an innovative opto-electrical laminated glass that composed of two layers of toughened glass on the outer side, smart film in the middle and other composite materials to form a sandwich-like structure. All those materials stick together firmly through special lamination process. When power off, it is opaque；when power on, it turns transparent instantaneously.

The double glazed smart glass, also called isolating smart glass, is an innovative opto-electrical double glazed glass that presents different visual state by controlling the voltage. When no voltage is applied, the glass is opaque and when voltage is applied, the glass turns transparent. It consists of two pieces of glass, one of which was affixed with a smart film, being separated evenly by spacer and sealed around the surroundings. Among the two pieces of glass, a dry air space is formed, not only providing protection for the smart film but also enabling the glass to have good sound insulation and heat resistance features.
