Field emission display
A field emission display is a type of flat panel display using phosphor coatings as the emissive medium.
Field emission displays are very similar to cathode ray tubes. 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 electrons through a process known as field emission. A similar technology to be commercialized in 2005 is the SED (surface-conduction electron-emitter) display.
Like CRTs, FEDs are energy efficient and could provide a flat panel technology that features less power consumption than existing LCD and plasma display technologies. They can also be cheaper to make, as they have fewer total components. As of yet, however, there are no consumer production models available in the United States.
