Abstract (en)
[origin: WO9624152A1] A gated filament structure for a field emission display includes a plurality of filaments. Included is a substrate, an insulating layer positioned adjacent to the substrate, and a metal gate layer position adjacent to the insulating layer. The metal gate layer has a plurality of gates, the metal gate layer having an average thickness "s" and a top metal gate layer planar surface that is substantially parallel to a bottom metal gate layer planar surface. The metal gate layer includes a plurality of apertures extending through the gates. Each aperture has an average width "r" along a bottom planar surface of the aperture. Each aperture defines a midpoint plane positioned parallel to and equally distant from the top metal gate layer planar surface and the bottom metal gate layer planar surface. A plurality of filaments are individually positioned in an aperture. Each filament has a filament axis. The intersection of the filament axis and the midpoint plane defines a point "O". Each filament includes a filament tip terminating at a point "A". A majority of all filament tips of the display have a length "L" between each filament tip at point A and point O along the filament axis where, L </= (s + r)/2.
