Abstract:
A display device comprising:an envelope for enclosing a space containing a vacuum, said envelope further comprising a first pane of a transparent material and a second pane substantially parallel to said first pane; a substrate panel having first and second parallel sides, said substrate panel disposed between said first pane and said second pane and within said enclosed space of said envelope such that said substrate panel and said first pane are spaced from one another, said first side of said substrate panel being closer than said second side of said substrate panel to said first pane of said envelope; a plurality of conductive anode pads disposed on said first side of said substrate panel, said conductive anode pads being covered with light-emissive phosphor coatings; driver circuitry for selectively activating individual ones of said conductive anode pads, said driver circuitry being disposed on said second side of said substrate panel; a plurality of conductive vias connecting said conductive anode pads with said driver circuitry, a unique one of such conductive vias connecting each separate conductive anode pad to said driver circuitry; and an electron source disposed between said first side of said substrate panel and said first pane of said envelope and spaced from said substrate such that a vacuum space is maintained between said electron source and said conductive anode pads disposed on said first side of said substrate panel.
