ABSTRACT:
A flat panel display includes a magnetic material for focusing electrons onto a faceplate or phosphors of each pixel on a screen. In one embodiment, a display screen includes a faceplate having a magnetic material (30) deposited thereon. In an alternate embodiment, a field emission display including a substrate (11) with a cathode conductor (12); electron emitting tips (13) disposed over the cathode conductor (12); an insulator (14) disposed around the electron emitting tips (13); a conductive gate (15) over the insulator (14); and a magnetic material layer (19) for focusing electrons emitted from the emitting tips (13).
