ABSTRACT:
A plurality of field emission device cathodes each generate emission of electrons, which are then controlled and focused using various electrodes to produce an electron beam. Horizontal and vertical deflection techniques, similar to those used within a cathode ray tube, operate to scan the individual electron beams onto portions of a phosphor screen in order to generate images. The use of the plurality of field emission cathodes provides for a flatter screen depth than possible with a typical cathode ray tube.
