PRIVA-LITE® is laminated glazing comprised of two sheets of glass, either clear or tinted, and a liquid crystal film. The LC film and the glass panes are assembled of two interlayer films. The polymer and the liquid crystals are encapsulated in the LC film.
Both faces of the film are covered with a transparant electrical conductive coating. Both conductive coatings are connected to a flat electrical busbar, which is fixed on one of the large edges of the glass. These busbars connect the glazing to the power supply. When the glass is switched off, the liquid crystals are randomly scattered and diffuse light in all directions. It’s translucent and prevents both sides from seeing through the glass. When the glass is switched on the crystals line up and reorientate themselves and the glass is transparent.
