Abstract
An apparatus (10) having a switchable display/mirror (11) and a display driver (12). In one mode of operation the switchable display/mirror provides a visual display to a viewer (using, for example, an emissive array). In another mode of operation the switchable display/mirror provides a mirror-like reflection. In a preferred embodiment, the switchable display/mirror includes a transparent organic light emitting diode array (31) that operates in conjunction with a reflective electrode (32) and a switchable circular polarizer (23). In one embodiment the switchable circular polarizer (23) can be comprised of a switchable linear polarizer (34) and a quarter waveplate (36).
