摘要： An electron emitter plate (110) for an FED image display has an extraction (gate) electrode (22) spaced by an insulating spacer (125) from a cathode electrode including a conductive mesh (18). Arrays of microtips (14) are located in mesh spacings (16), within apertures (26) formed in extraction electrode (22) and subcavities (141) formed through apertures (26) in insulating spacer (125). Subcavities (141a) are open to row-adjacent and column-adjacent subcavities (141b, 141c) to form larger main cavities (144). Posts (143) of insulating spacer (125) separate diagonally-adjacent cavities (141d). Subcavities (141) are formed by over-etching a layer of insulating spacer material (25) through apertures (26) before or after forming microtips (14) through the same apertures (26). Over-etching reduces the dielectric constant factor of gate-to-cathode capacitance in the finished structure.

Each thyristor has a lower conducting surface that is electrically connected to one of the input lines and an upper conducting surface that is electrically connected to one of the output lines.

摘要： An anode plate 50 for use in a field emission flat panel display device comprises a transparent planar substrate 58 having a plurality of electrically conductive, parallel stripes 52 comprising the anode electrode of the device, which are covered by phosphors 54.sub.R, 54.sub.G and 54.sub.B. A substantially opaque, electrically insulating material 56 is affixed to substrate 58 in the spaces between conductors 52, acting as a barrier to the passage of ambient light into and out of the device. The electrical insulating quality of opaque material 56 increases the electrical isolation of conductive stripes 52 from one another, reducing the risk of breakdown due to increased leakage current. Opaque material 56 preferably comprises glass having impurities dispersed therein, wherein the impurities may include one or more organic dyes, selected to provide relatively uniform opacity over the visible range of the electromagnetic spectrum. Alternatively, the impurities may include the black oxide of a transition metal such as cobalt. Opaque material 56 is formed by mixing a TEOS solution with a dye or a source of metallic ions, spinning or spreading the mixture on glass substrate 58, and curing the mixture to drive out the organics and solvents. Two methods of fabricating anode plate 50 are disclosed.

摘要： A porous dielectric material such as silica-based aerogel is used as the dielectric layer 48 between the gate and the cathode on the emitter plate 12 of a field emission device. Aerogel, which can have a relative dielectric constant as low as 1.03, is deposited over the resistive layer 44 of the emitter plate 12. Metal layer 49, functioning as the gate electrode, is subsequently deposited over the aerogel layer 48. The use of aerogel as a gate dielectric reduces power consumption. In a disclosed embodiment, aerogel layer 48 is comprised of sublayers 48a, 48b, and 48c of aerogels of differing densities, thereby providing better adhesion of the aerogel gate dielectric to both the resistive layer 44 and metal layer 49. Methods of fabricating the aerogel gate dielectric are disclosed.

摘要： A spacer 40 for use in a field emission device comprises a comb-like structure having a plurality of elongated filaments 42 joined to a support member 44. The filaments 42, which may be glass, are positioned longitudinally in a single layer between the facing surfaces of the anode structure 10 and the electron emitting structure 12. Support member 44 is positioned entirely outside the active regions of anode structure 10 and emitting structure 12. Spacer 40 provides voltage isolation between the anode structure 10 and the cathode structure 12, and also provides standoff of the mechanical forces of vacuum within the assembly. In a second embodiment, spacer 50 comprises elongated filaments 52 joined at each end to a support member 54a and 54b, the additional support facilitating handling, fabrication and assembly. In an additional embodiment, a filament 70 of nonuniform diameter contacts planar surfaces 74 and 76 only at the high spots 72 of filament 70, thereby reducing the shadowing of the beam on the display surface.
