ABSTRACT:
A touch-sensitive device for computer data entry from the presentation on a scanned, thin-film, electroluminescent display. A transparent conductive film is suspended over the display face. Touching that film at a predetermined point in the display capacitively couples scanning voltages (which are time-base synchronous and related to the touched point) to an amplifier and then to a utilization device (computer, for example).
