Field emission display panel equipped with two cathodes and an anode

A method for fabricating a field emission display panel with two cathodes and an anode comprising the steps of:

• providing a first plate formed of an electrically insulating material,
• forming a first plurality of electrically conductive strips of a substantially transparent material on said first electrically insulating plate, said first plurality of electrically conductive strips being an anode,
• forming a first plurality of emitter stacks on said first electrically insulating plate by a thick film printing technique parallel to a transverse direction of said first electrically insulating plate, each of said emitter stacks comprises sequentially a layer of a dielectric material, a layer of a second electrically conductive material and a layer of nanotube emitters with said layer of dielectric material intimately contacting said fist electrically insulating plate,
• forming a second plurality of nanotube emitters spaced-apart and insulated from each other in two parallelly situated and spaced-apart rows on top of each said emitter stack from said layer of nanotube emitters, said second plurality of nanotube emitters being a first cathode,
• forming a second plurality of fluorescent coating strips on said first plurality of electrically conductive strips each for emitting a red, green or blue light when activated by electrons emitted from said second plurality of nanotube emitters on said first plurality of emitter stacks,
• positioning a second plate formed of an electrically insulating material 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 material coated-forming a second cathode, and
• joining said first and second plates together by side panels and forming a vacuum-tight cavity therein.
