Abstract
The present invention teaches a matrix addressed flat panel display device. A substrate is contained within a vacuum envelope with a translucent pane to allow viewing of the image. The substrate panel has one side covered with phosphor-coated anode pads, and the other side with driver circuitry for selectively activating individual conductive anode pads by electric connections using vias or similar electric connections through the substrate. An electron source such as thermionic filaments are disposed between the phosphor-coated anode pads and the translucent pane.
