LCD Privacy Film is made of two layers of transparent conductive film sandwiched with polymer dispersed liquid crystal (PDLC) material. The film is then laminated between two pieces of glass. When electricity is applied to the film, the liquid crystals line up and ESG Switchable™ becomes transparent. When the power is turned off, the liquid crystals return to their normal scattering positions and turn the glass to opaque. The Liquid Crystal Privacy film is encapsulated between layers of glass in a protective laminate construction. ESG Switchable™ incorporates 5 mm low iron tempered glass as standard, offering a considerably higher light transmission when transparent.

However, as ESG manufacture the product in the UK customers can select from a wide range of glass types and colours to suit their project requirements. The outside leafs are made up of glass (normally 5 or 6 mm toughened glass) each side, then a PVB interlayer is inserted on each side to trap and hold the Liquid Crystal Privacy film.

The Liquid Crystal Privacy film is made up from electrically conductive coatings, a polymer matrix and liquid crystals. This film is connected to the power supply via bus bars, electrical wiring and a transformer.
