A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode-ray tubes, each tube producing a single sub-pixel, grouped in threes to form red-green-blue (RGB) pixels.
