Image display apparatus and method of fabrication thereof

Abstract From the Canadian patent

An image display apparatus comprising an insulating substrate having electron sources controlled by X-Y matrix electrodes and a face plate coated with a phosphor material in opposed relationship with the substrate is disclosed. An electron source at each intersection of the X-Y matrix control electrondes is made up of a plurality of cold cathodes connected to an X-control electrode and a plurality of gate electrodes connected to a Y-control electrode opposed to the cold cathodes in the same plane, and the electron source is formed on the substrate surface on other than the X- and Y-control electrodes. A voltage applied between the cold cathodes and gate electrodes arranged in opposed …
