field emission display (FED)

Definition

field emission display (FED)

A field emission display (FED) is a new type of flat-panel display in which electron emitters, arranged in a grid, are individually controlled by "cold" cathodes to generate colored light. Field emission display technology makes possible the thin panel of today's liquid crystal displays (LCD), offers a wider field-of-view, provides the high image quality of today's cathode ray tube (CRT) displays, and requires less power than today's CRT displays.

Some FED products are now available and developers continue to refine the technology. Two companies working on this technology are Candescent Technologies and PixTech.
