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.
