Abstract
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.
