Mirror with built-in display
First Claim
1. A polarizing mirror for viewing purposes having a first plane reflecting light of a first kind of polarization to a viewing side, the polarizing mirror passing light of a second kind of polarization and being provided with a display device at its non-viewing side, which display device during use provides light of the second kind of polarization, the polarizing mirror being switchable between a state passing light of the second kind of polarization and reflecting light of the first kind of polarization and a state passing light of both kinds of polarizing, wherein a switchable polarizer is located between the polarizing mirror and a ¼

foil.

Abstract
A mirror display device which may be simultaneously used for display purposes, based on a display, wherein the display device during use provides light of a first (circular) polarization, with a switchable polarizing mirror placed in front of it. The reflectivity of such a mirror display device may be enhanced by providing a second switchable (circular) polarizer between the display device and the polarizing mirror.
