Abstract: A method for making a storage target for use with a cathode ray tube involves forming an insulating material at least around each of an array of collector electrode members which has been formed onto a conductive layer but leaving outer ends of the collector electrode members exposed and fixing a layer of dielectric storage material onto the conductive layer and in engagement with the insulating material around the collector electrode members to prevent luminance around the collector electrode members.

Abstract: A bistable storage cathode ray tube wherein the bistable storage target thereof has a conductive layer provided on an insulating support member, the conductive layer including a multiplicity of collector electrode members having insulating material covering at least the collector electrode members except for an area thereof. A layer of storage dielectric material is provided on the conductive layer and the insulated collector electrode members extend through the layer of dielectric material. The exposed conductive area of the collector members collect secondary electrons emitted from written areas of the dielectric layer and provide a substantially uniform potential over the target surface. The interface between the dielectric layer and the insulating material around the collector electrode members provides isolation between the dielectric layer and the collector electrode members thereby minimizing luminance around the collector electrode members.
