Abstract

The present invention provides an FED with a getter material deposited and activated on the substrates of the faceplate and the baseplate of the FED. In one embodiment of the invention, a large FED includes a faceplate, a baseplate, and an unactivated non-evaporable getter material. The faceplate has a transparent substrate with an inner surface, and a cathodoluminescent material disposed on a portion of the inner surface. The baseplate has a base substrate with a first surface and an emitter array formed on the first surface. The baseplate and the faceplate are coupled together to form a sealed vacuum space in which the inner surface and the first surface are juxtaposed to one another in a spaced-apart relationship across a vacuum gap. The unactivated non-evaporating getter material is deposited directly on the inner surface and/or the first surface. The unactivated non-evaporating getter material may alternatively be deposited on a thin film of bonding material that is disposed on the inner surface and/or the first surface.
