Abstract

This invention relates to the combination of a transparent touch-sensitive screen overlaying an electronically composable display for use as a key entry device with programmable legends. Although the prior art includes touch-sensitive screens with fixed displays, as found, for example, on capacitive-actuated keyboards and control panels, the displays nevertheless are fixed and not electronically alterable. Likewise, Hebalkar * conceived a CPU writeable display surface for backlighting a keyboard having transparent key tops for the purpose of altering abbreviations of functions associated with individual keys on a CPU-controllable basis.

Touch-Sensitive Screen Proximate and Electronically Composable Display

This invention relates to the combination of a transparent touch-sensitive screen overlaying an electronically composable display for use as a key entry device with programmable legends. Although the prior art includes touch-sensitive screens with fixed displays, as found, for example, on capacitive-actuated keyboards and control panels, the displays nevertheless are fixed and not electronically alterable. Likewise, Hebalkar * conceived a CPU writeable display surface for backlighting a keyboard having transparent key tops for the purpose of altering abbreviations of functions associated with individual keys on a CPU-controllable basis. He envisioned the keyboards replaced by backlighted liquid crystal displays or liquid light-emitting diodes in character display sizes of a magnitude small enough to fit on a standard key top. An electronically composable display in combination with the touch-sensitive screen permits variations in the position, size, and orientation of the keys after a manner not envisioned by the prior art. The size, location, and legend of the "keys" can be changed at will to fit the application. In addition, unlike the prior art, the display can be used for operator-oriented messages without disturbing the main display. This display keypad could be used as a telephone keypad for a telephone application, special function keys, and cursor movement for a text-editing applicatio...
