ABSTRACT:
A display device for use in conjunction with a computer system includes a cathode having a layer of conductive material and a layer of low-effective work function material deposited over the conductive material wherein the low-effective work function material has an emission surface comprising a plurality of distributed localized electron emission sites. The emission sites may have electrical properties which are discontinuous from each other. The emission surface may be relatively flat.
