Field emission

A type of flat panel display using phosphor coatings as the emissive medium, which works as a variation on the CRT idea. Instead of a single electron gun, a field emission display (FED) uses a large array of fine metal tips, one positioned behind each phosphor dot, to emit excitatory electrons.

Since it builds on a century of know-how honed on CRTs, FEDs hold promise. As of yet, however, there are no consumer production models available in the United States.
