ABSTRACT:
An interface circuit and method for multiple discharge gaseous display and/or memory panels utilizing the slope characteristics of individual discharge units in a multiple discharge panel to control the status of individual units without effecting the status of other individual discharge units. A low level voltage signal from an addressing logic system is translated into a high voltage unidirectional pulse which is added to a periodic alternating voltage at selected times to modify the slope of discharge potential of a charge storage discharge unit to control on and off states of selected discharge units.
