Energy efficient interactive display with energy regenerative keyboard
First Claim
1. An electronic device comprising:
- an interactive display having an interactive mode and a non-interactive mode, the interactive display comprising;
a touchscreen image display device that displays a user-interactive imaged keypad in at least a portion of the image display device when the interactive display is in the interactive mode and that displays other image data in the at least a portion of the image display device when the interactive display is in the non-interactive mode;
a substantially transparent physical keypad that is moveable relative to the touchscreen image display device so as to provide tactile feedback to a user indicating location of keys within the imaged keypad;
one or more permanent magnets disposed within the physical keypad; and
one or more charged electrical circuit elements disposed within the touchscreen image display device and oriented so that movement of the one or more permanent magnets relative to the one or more charged electrical circuit elements resulting from movement of the substantially transparent physical keypad results in generation of electricity that is fed back to the interactive display as a power source.

17. An electronic device comprising:
-
a housing comprising a back surface and a front surface, the front and back surfaces being angled relative to one another; and an interactive display having an interactive mode and a non-interactive mode, the interactive display comprising; an image display device disposed at one of the back or front surfaces of the housing that displays a user-interactive imaged keypad in at least a portion of the image display device when the interactive display is in the interactive mode and that displays other image data in the at least a portion of the image display device when the interactive display is in the non-interactive mode; and a substantially transparent physical keypad disposed at the other of the back or front surfaces of the housing that provides tactile feedback to a user indicating location of keys within the imaged keypad. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
