  • Patent number: 4027191
    Abstract: There is disclosed a multiple gaseous discharge display/memory panel having an electrical memory and capable of producing a visual color 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 a series of parallel-like conductor (electrode) members, the conductor members behind each dielectric material member being transversely oriented with respect to the conductor members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes each of which constitutes a discharge unit, at least one dielectric material member containing a photoluminescent phosphor geometrically adjacent to at least one discharge unit, such that the phosphor is excited with ultraviolet radiation emitted from the gaseous discharge of such unit and such that the UV excited phosphor emits visible light of a brightness and intensity sufficient for visual display.

  • Patent number: 3989982
    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 a series of parallel-like conductor (electrode) members, the conductor members behind each dielectric material member being transversely oriented with respect to the conductor members behind the opposing dielectric material member so as to define a plurality of discrete discharge volumes constituting a discharge unit, the dielectric having at least one electron emissive substance applied to the surface thereof in an amount sufficient to decrease the operating voltages of the panel. Typical electron emissive substances contemplated include Group IA elements, Group IA oxides, barium, GaAs, GaP, InAs, InSb, InP, NiO, CsF, CsI, AgOCs, and AuOCs.
