We report on the development of solid-state hydrogen sources utilizing thin-film metal hydrides. We demonstrate that integration of these metal hydride thin films facilitate a practical method to introduce controlled amounts of hydrogen into sealed field emission display assemblies. To prove the concept, we operated Mo field emitter arrays without emission current loss for 400 h of continuous operation with titanium-hydride-coated stainless steel anode plates. Comparable arrays operated in the absence of hydride films, but in ultrahigh vacuum, had emission current degradation of over 50% in less than 100 h of operation. © 2001 American Institute of Physics.
