Abstract
A device and method for forming a device including electron emitters. The method includes exposing a first face of a sheet of bundled fiber segments to a reactive liquid to allow first ends of the fiber segments to react with the reactive liquid to remove material therefrom. A coating material is deposited on the first face which has the material removed. The method also includes exposing a second face of the sheet of bundled fiber segments to a reactive liquid to allow second ends of the fiber segments to react with the reactive liquid to remove material therefrom to expose the coating material.
Claims9
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.
