Abstract: An electron image storage tube is provided with a bistable storage target employing a transparent faceplate on the inside surface of which there is provided a transparent coating of conductive material. A layer of storage dielectric phosphor is disposed onto the coating of conductive material and an array of conductive fluorescent dots in electrical connection with the conductive coating extends through the layer of storage phosphor and beyond the outer surface of the storage phosphor. The conductive fluorescent dots provides collector electrode means for collecting secondary electrons emitted from charge images that have been written onto the storage dielectric phosphor so that such charge images remain as stored information thereon and the conductive fluorescent dots will enable non-stored electron images having a high degree of brightness and the same general or different color to be displayed simultaneously with the stored charge images on the same general area of the target structure.

Abstract: An admixture of Yttrium oxide, or yttrium oxysulfide, or yttrium oxide or yttrium oxysulfide activated by a rare earth element and P1 phosphor, manganese-activated zinc orthosilicate provides a viewable bistable storage target for cathode ray tubes having increased operating life.

Abstract: A cathode ray storage tube provided with a storage target having a multiplicity of segments of the collector electrode extending through the dielectric layer of the storage target. These segments comprise dots or continuous or broken protrusions of conductive particles that have been photo-deposited into position onto the collector electrode and then the storage dielectric layer is applied thereover which has proper thickness so that the segments extend above the dielectric thereby providing collector areas for collecting secondary emitted electrons from the dielectric.
