A closer look at SED, FED technologies
Author: Richard Fink, Zvi Yaniv, L. H. Thuesen, Igor Pavlovsky

The surface-conduction electron-emitter display (SED) and the field emission display (FED) have many components in common, such as the anode configuration and phosphors used on the anode, and much of the assembly process. But significant differences exist in the emitter structure. This article discusses the similarities and differences between the two technologies, and their effect on performance.
