Abstract
A flat panel display of the field emission cathode type having polyimide spacers or pillars separating the emitting surface and display face of the same and a method of forming the spacers by integrated circuit techniques.
Claims5
An electronic device comprising:
- an array of field emission cathodes providing an electron emitting surface;
- a display panel having a face including an anode opposing said surface;
- and
- a plurality of prebaked spacers of uniform height of an organic polymer and substantially free of volatile material, said spacers extending between said surface of said face;
- said electron emitting surface and said display panel being sandwiched together with said spacers defining a space therebetween, said space being subjected to a vacuum during emission of electrons from said field emitting surface to said display panel.
