FIELD EMITTER DEVICES INCORPORATING AN IMPROVED BALLAST RESISTOR

摘要

A field emitter device is disclosed which comprises a layer of a non-conducting support material having thereon successive layers of an address electrode, a dielectric anodic metal oxide layer and, optionally, lastly, a grid electrode, the dielectric anodic metal oxide layer possessing an array of pores extending from the surface in contact with the grid electrode to the address electrode, said pores containing wires which extend from the address electrode to the surface of the anodic metal oxide layer in contact with the grid electrode, at least one section along the wires not in contact with the address electrode being formed of a resistive material.
