field emission display definition
hardware (FED) A type of
flat panel display in which field emitting cathodes bombard a phosphor coating causing it to emit light.
A field emission display is similar to a
cathode ray tube but only a few millimeters thick. They use a large array of fine metal tips or carbon nanotubes (which are the most efficient electron emitters known), to emit electrons through a process known as field emission. Many of these are behind each phosphor dot so FEDs do not display dead pixels like LCDs even if 20% of the emitters fail.
Sony is researching FED because it is the flat-panel technology that comes closest to matching the picture of a CRT.
