Abstract
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 charge storage members which are respectively backed by a series of parallel-like conductor (electrode) members, the conductor members behind each charge storage member being transversely oriented with respect to the conductor members behind the opposing charge storage member so as to define a plurality of discrete discharge volumes constituting a discharge unit, each charge storage member being comprised of a continuous thin film of dielectric material having a thickness of 150,000 angstrom units or less.
