Array field emission display device utilizing field emitters with downwardly descending lip projected gate electrodes

摘要

An array field emitter device utilizes field emission devices disposed in a matrix or array each comprising an opening in an insulating layer with an upwardly extended cathode with a tip disposed centrally within the opening and a gate electrode substantially concentric with each the cathode tip and having a lip extending into the opening forming a downwardly descending lip projection. Such an array display device can be of the multiplex driven type or can be of the active matrix type.
