Abstract

There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual display, the panel being characterized by an ionizable gaseous medium in a gas chamber formed by a pair of opposed dielectric material charge storage members which are respectively backed by an array of electrode (conductor) members such that each array of electrode members is insulated from the gaseous medium by a dielectric member, the electrode members behind each dielectric material member being oriented with respect to the electrode members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes, each discharge volume constituting a discharge unit, the dielectric material being selectively enriched with at least one Group IA or IIA element in an amount sufficient to provide operating voltages which are substantially uniform and which do not significantly change with time.
