Emissive flat panel display with improved regenerative cathode

摘要: Method and apparatus are presented for the generation, regeneration, transplantation of field enhancing whiskers to provide an improved cathode in flat panel displays particular, other applications. Such applications comprise devices which there is emissive structure producing electrons. There dear advantages instant invention case a display requires relatively large area, because present avoids excessive power loss due radiation conduction by permitting operation at significantly lower temperature than if it operated solely as thermionic emitter. The combination moderately elevated enhanced electric allows thermo-field assisted emission.
