Patent ID: 7009336

Claim:
A field emission device comprising: a cathode plate formed by: exposing a first face of a sheet of bundled fiber segments to a reactive liquid to allow first ends of said fiber segments to react with said reactive liquid to remove material therefrom, wherein outer surfaces of adjacent fiber segments are in contact with each other; depositing a coating material on said first face with said material removed; and exposing a second face of said sheet of bundled fiber segments to a reactive liquid to allow second ends of said fiber segments to react with said reactive liquid to remove material therefrom to expose said coating material; and an anode plate formed by: providing a transparent substrate having a transparent conductive material deposited thereon; forming a dielectric spacer on said transparent substrate; and etching selective areas of said dielectric spacer to form chambers for containing color phosphors; said anode plate and said cathode plate formed together to align said etched selective areas wit said exposed coating material.
