Flat storage CRT and projection display

In a storage cathode ray tube of the type wherein a mesh collector, and a dielectric storage site array are positioned between an area electron source and a phosphor screen, the improvement comprising:

• a semiconductor wafer having a first integral layer comprising said mesh collector, and wherein said dielectric storage site array comprises;
• a through hole in said semiconductor wafer;
• a layer of dielectric material on sidewalls of said through hole for charge storage by collecting electrons from an area electron source, and emitting electrons by way of secondary electron emission;
• said semiconductor wafer having thereon an addressable array of transistors for controlling the passage of electrons from said area electron source to said dielectric storage site array;
• said addressable array of transistors selecting a predetermined site in said storage site array for writing by electrons from said area electron source;
• a source of an associated transistor being disposed along said sidewalls of said through hole, and subsequently surrounding said layer of dielectric material;
• and
• stored charge on a surface of said dielectric layer in said storage site depending upon a potential set at said source.
