Abstract:
The patent describes a flat panel display device having a striped address system wherein an electron beam from a selected one of several elemental emitting strips of either a field emission type cathode, a photoemissive cathode or a thermionically emissive cathode is caused to impinge upon a corresponding region of a phosphor screen to produce visible emission from said region, said device including means for multiplying the number of electrons emitted from the cathode so as to permit use of a cathode of smaller current density.
