Abstract: A plural-color cathodoluminescent screen for use in a cathoderay tube wherein at least two layers of light-emitting phosphors have therebetween a separation layer of electrically conductive oxide material that is substantially translucent to electromagnetic radiation and substantially opaque to the penetration of electron beams of predetermined velocity. The screen includes a nucleation to achieve the uniform disposition of an oxidizable metal which when subsequently heated forms the metallic oxide of the separation layer.

Abstract: The combination of a color television receiver and a display system for presenting slide transparencies, movies or other image mediums upon the color cathode ray tube of the television receiver. The slide or other medium is scanned by a flying spot cathode ray tube which, in conjunction with dichroic mirrors and suitable filters separates the information derived from the scan of the medium into its representative color components, translates the representative color components into processed electrical signals and couples the processed signals directly to appropriate electrodes of the color cathode ray tube. The flying spot cathode ray tube is provided with a fixed focus and has a screen comprised of an admixture of Y3A15012:Ce and Ca2A12SiO7:Ce phosphors in approximately the ratio of 3 to 1 by weight. Also disclosed as an alternate for Ca2A12SiO7:Ce is ZnS: Ag:Ni.
