— A hopping‐electron field‐emission display (HOPFED) is a field‐emission display (FED) with a new and revolutionary spacer structure. In a HOPFED, two insulator plates, referred to as hop and flu spacers, are sandwiched between the emitter and front plate. The objective of this spacer structure is to improve the performance of a FED substantially, notably contrast, color purity, and luminance uniformity. Another advantage is the reduced sensitivity of ion bombardment on the field emitters. We show by numerical methods that both the luminance uniformity and the sensitivity of ion bombardment improve substantially in a HOPFED.
