field emission display


field emission display

(hardware)(FED) A type of flat panel display in which fieldemitting cathodes bombard a phosphor coating causing it toemit light.

A field emission display is similar to a cathode ray tubebut only a few millimeters thick. They use a large array offine metal tips or carbon nanotubes (which are the mostefficient electron emitters known), to emit electrons througha process known as field emission. Many of these are behindeach phosphor dot so FEDs do not display dead pixels like LCDseven if 20% of the emitters fail. Sony is researching FEDbecause it is the flat-panel technology that comes closest tomatching the picture of a CRT.
