Abstract
An apparatus for stabilizing the threshold voltage in an active matrix field emission device is disclosed. The apparatus includes the formation of radiation-blocking elements between a cathodoluminescent display screen of the FED and semiconductor junctions formed on a baseplate of the FED.
Claims8
A display device having an anode and a plurality of emitters comprising:
- at least one emitter located opposite to the anode being electrically isolated therefrom;
- an insulating layer having at least one conductive line embedded therein;
- a P/N junction disposed adjacent the at least one emitter;
- and
- a radiation blocker for passing electrons emitted from the at least one emitter to the anode while blocking radiation from at least a portion of the anode.
