The Free On-line Dictionary of Computing (19 January 2023):

field emission display
FED

    (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.
