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.

Claims

1. An electronic device comprising:

a housing sized so that said electronic device is portable;

a display mounted in said housing, said display showing the state or operation of said portable electronic device;

a switchable mirror covering said display and operable for switching from a transparent state to a reflecting state responsive to a switch in said portable electronic device; and

a backlight behind said display,

wherein said switchable mirror covers a center of said display with a margin of said display extending completely around said switchable mirror so that said backlight from said display margin can illuminate a viewer of said switchable mirror.

2. The electronic device of claim 1 wherein said housing is sized to be held in a person'"'"'s hand.

3. The electronic device of claim 2 wherein said display is switched off when said switchable mirror switches to said reflecting state.

4. The electronic device of claim 2 wherein said switchable mirror is switched to said reflecting state when said portable electronic device is switched off.

5. The electronic device of claim 2 wherein said portable electronic device is selected from the group comprising cellular telephones, PDAs, music players, and GPS devices.

6. The electronic device system of claim 2 wherein said switchable mirror is flat.

7. The electronic device of claim 2 wherein said switchable mirror includes a concave surface facing away from said display.

8. The electronic device of claim 1 wherein said portable electronic device comprise a laptop computer.

9. The electronic device of claim 8 wherein said display is switched off when said switchable mirror switches to said reflecting state.

10. The electronic device of claim 8 wherein said switchable mirror is switched to said reflecting state when said portable electronic device is switched off.

11. The electronic device system of claim 8 wherein said switchable mirror is flat.

12. The electronic device of claim 8 wherein said switchable mirror includes a concave surface facing away from said display.

13. The electronic device of claim 8 wherein said backlight comprises light-emitting diodes.

14. The electronic device of claim 1 wherein said backlight comprises light-emitting diodes.
