Abstract
A field emission display which includes thin film resistors disposed between the electron-emitting elements of a cathode and a conductive support which provides electrical connection to said electron-emitting element through said thin film.
Claims5
A field emission display comprising:
- a conductive anode,
- a light emitting material which emits light in response to electron bombardment carried by said conductive anode,
- a field emission cathode spaced from said anode including:
- a first substantially transparent electrode,
- a plurality of ballast resistive elements of predetermined thickness disposed on said first electrode,
- a plurality of electron-emitting elements, one for each resistive element, disposed on said resistive elements whereby the resistive elements are in series with each of said electron-emitting elements,
- a second substantially transparent conductive electrode spaced from said first conductive electrode, said second conductive electrode having a plurality of holes, one opposite from each of said electron-emitting elements, and
- a transparent insulating layer between said first and second conductive electrodes.
