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 conductor (electrode) members, the conductor array behind each dielectric material member being appropriately oriented with respect to the conductor array behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the surface of at least one dielectric material member comprising at least one inorganic non-oxide lead compound, said compound being present in an amount sufficient to improve the operating characteristics of the panel, especially more uniform and/or lower panel operating voltages.
