Abstract:
A field emission display comprising:a baseplate comprising: a substrate; an emitter formed on the substrate, the emitter being electrically coupled to a first node; a dielectric layer formed on the substrate and having an opening formed about the emitter; a conductive extraction grid formed on the dielectric layer and having an opening formed about the emitter; and a focusing electrode formed on the substrate and having an opening formed above the emitter such that the focusing electrode physically confines electrons emitted from the emitter, the focusing electrode being electrically coupled to the first node; a current source coupled to the first node; and a faceplate comprising: a transparent insulating viewing layer; a transparent conductive layer formed on the transparent viewing layer; and a cathodoluminescent layer formed on the transparent conductive layer, the faceplate positioned with the cathodoluminescent layer towards the substrate.
