Abstract

Portable electronic devices with displays having switchable mirrors are described. The switchable mirror covers the display and is capable of switching from a transparent state to a reflecting state responsive to a switch in the portable electronic device. In one embodiment of the present invention, the display is switched off when the switchable mirror switches to its reflecting state. In another embodiment of the present invention, the switchable mirror is switched to its reflecting state when the portable electronic device is switched off.
