  • Patent number: 6255773
    Abstract: A cathodoluminescent anode for a field emission display (FED) includes a substrate on which an array of phosphor elements is formed, with at least two such elements spaced by a gap adapted to receive a spacer when the anode is assembled to a cathode. In one embodiment, a conductive layer disposed over the phosphor elements has a portion disposed in the gap, in contact with and electrostatically and mechanically bonded to the substrate. In another embodiment, the conductive layer has an aperture in the gap to expose a portion of the substrate. Also described are techniques for fabricating the FED anodes.
