Abstract:
A field emission display panel equipped with two cathodes and an anode comprising:a first plate formed of an electrically insulating material, a first plurality of emitter stacks formed substantially equally spaced from each other at a predetermined spacing in a longitudinal direction on said first electrically insulating plate, each of said emitter stacks being positioned parallel to a transverse direction of said first insulating plate and comprises sequentially a layer of a dielectric material, a layer of a first electrically conductive material and a layer of nanotube emitters with said layer of dielectric material intimately contacting said first electrically insulating plate, said layer of nanotube emitters being formed in two rows spaced-apart and insulated from each other, a second plurality of nanotube emitters being formed spaced-apart and insulated from each other in each row, a second plurality of electrically conductive strips being formed of a substantially transparent material and situated in-between said plurality of emitter stacks insulated from each other by said layer of dielectric material, a second plurality of fluorescent coating strips formed on said second plurality of electrically conductive strips each for emitting a red, green or blue light upon activation by electrons emitted from said second plurality of nanotube emitters on said first plurality of emitter stacks, a second plate formed of an electrically insulating material positioned over and spaced-apart from said first plate, said second plate having on a surface facing said first plate a layer of said substantially transparent conductive material coated, and a plurality of side panels joining peripheries of said first and second plates together forming a vacuum-tight cavity therein.
