Abstract
Abstract There is disclosed a gas discharge device containing at least two electrodes, at least one of the electrodes being insulated from the gas by a dielectric member. There is particularly 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, each of which is respectively backed by an array of electrodes, the electrodes behind each dielectric material member being oriented with respect to the electrodes behind the opposing dielectric material member so as to define a plurality of discrete discharge units. At least one dielectric insulating member contains a predetermined beneficial amount of a source of at least one element selected from Se, Te, or Po. The selected element or elements may be utilized in any suitable form, such as a compound, mineral, and/or elemental. Likewise, it may be incorporated into the dielectric by any suitable means, including being applied as a layer within the dielectric or on the surface thereof.
