A Solid State Oscilloscope Display

A new solid-state display device utilizing certain unique properties of piezoelectric and electroluminescent materials is described and the principles of operation are reviewed. The device requires only four properly timed electrical inputs to produce a spot of light at any selected point on the display panel. The timing relationships are derived and a system capable of producing the required drive signals is described. Oscilloscope patterns are generated on the panel by a point-by-point plot of suitably processed X-and Y-input signals.
