Abstract
A process for producing a field emitter flat display includes providing a supported porous layer of a non-evaporable getter material by depositing the non-evaporable getter material on a substrate followed by sintering the deposited material. The substrate having the porous layer of non-evaporable getter material thereon is then housed in an inner space defined by opposing plates. The inner space is then evacuated and hermetically sealed. The non-evaporable getter material is preferably deposited by preparing a suspension of non-evaporable getter material particles in a suspending medium, coating a surface of a substrate with the suspension by, e.g., spraying, and sintering the coating.
