ABSTRACT:
A cathodoluminescent display device is composed of a plurality of channels. Each of the channels includes spaced guide meshes between which electrons from an electron gun are propagated as beams. At the end of the channels away from the electron gun is a collector and a deflection electrode. The guide meshes are extended between the collector and deflection electrode. Collection apertures in the extended portions pass electrons to the collector. Collection of the electrons by the collector generates a signal which is sensed and used to maintain uniformity of the characteristics of the beams.
