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.
Claims20
A process for producing a field emitter flat display comprising:
- a) providing a porous layer by depositing a non-evaporable getter material on a substrate and by sintering said deposited material, a support layer is formed which separates said porous layer from said substrate;
- b) housing said porous layer in an inner space;
- and
- c) evacuating and hermetically sealing said inner space.
A process for producing a field emitter flat display comprising:
- preparing a suspension of non-evaporable getter material particles in a suspending medium;
- spraying a surface of a supporting substrate with said suspension for a first period of time;
- pausing for a second period of time to allow volatile components in said suspending medium to at least partially evaporate;
- sintering said non-evaporable getter material particles to form a porous layer of non-evaporable getter material on said supporting substrate;
- housing said supporting substrate having said porous layer of non-evaporable getter material thereon in an inner space;
- and
- evacuating and hermetically sealing said inner space.
