Patterned ion-bombarded graphite electron emitters are disclosed as well as processes for producing them. The electron emitters are produced by forming a layer of composite of graphite particles and glass on a substrate then bombarding the composite with an ion beam. The electron emitters are useful in field emitter cathode assemblies which are fabricated into flat panel displays.

Ion-bombarded graphite electron emitters

Patterned graphite electron emitters are disclosed. These field emitters find particular usefulness in field emitter cathodes and display panels. These graphite field emitters can be formed by screen printing a paste comprised of graphite and electrically insulating material (glass frit) in the desired patterned paste and bombarding the fire product with an ion beam.

Ion bombarded graphite electron emitters

Wire-coated graphite electron emitters are disclosed. These field emitters find particular usefulness in field emitter cathodes, display panels and lighting devices. These graphite field emitters can be formed by coating a paste comprised of graphite and glass frit onto the wire, firing the paste and bombarding the fired product with an ion beam.

Coated-wire ion bombarded graphite electron emitters

Patterned ion-bombarded carbon electron emitters and the processes for producing them. The electron emitters are produced by forming a layer of composite of carbon particles and glass on a substrate then bombarding the composite with an ion beam. The electron emitters are useful in field emitter cathode assemblies which are fabricated into flat panel displays.

Past-deposited carbon electron emitters

Annealed carbon soot is useful as an electron field emitter. Field emitting cathodes made up of annealed carbon soot attached to the surface of a substrate are also provided. The field emitters and field emitter cathodes are useful in vacuum electronic devices, flat panel computer and television displays, emission gate amplifiers, klystrons and lighting devices.
