ABSTRACT:
A device, comprising a switchable optical panel and means for switching the panel between a reflecting state and a transmitting state. The switchable optical panel includes a transparent optically active layer having a first and a second major surface, a first reflective polarizer disposed on the first major surface and a second reflective polarizer disposed on the second major surface. The optically active layer preferably comprises a liquid crystal device and the switching means preferably comprises a system of drying electronics for applying voltage across the liquid crystal device. The invention also includes a switchable window and a transflective optical display.
