MULTI-TOUCH ACTIVE DISPLAY KEYBOARD
First Claim
1. A touch sensitive display device comprisinga display fabricated on a flexible substrate, the display having a viewing surface;
- anda plurality of touch sensitive elements under the display, each of the plurality of touch sensitive elements comprising a touch sensitive sensor, the sensors being operable by touching the viewing surface of the display, and each of the plurality of touch sensitive elements having an output for outputting a signal responsive to the viewing surface being touched,wherein each of the plurality of touch sensitive elements defines a region of the viewing surface in which the touch sensitive element produces an output in response to a touch, andwherein the plurality of touch sensitive elements are arranged such that two or more substantially simultaneous touches of different regions of the viewing surface produces output signals corresponding to the two or more touches of the viewing surface.
