METHOD OF FABRICATING A MULTIBEAM ELECTRON GUN STRUCTURE

摘要

A method of fabricating a multibeam single electron gun structure for an electron discharge device, such as a high resolution cathode ray tube, wherein a plurality of beams emanating from a common emission plane are separately modulated by a planar arrangement of separate control electrode members each having a beam aperture therein forming an aperture array. At least one accelerating-collimating electrode plane having a similar array of apertures is oriented in spaced and substantially parallel relationship with the control grid plane to provide a collimated array of beams directed to impinge the cathodoluminescent screen in a defined pattern array.
