ABSTRACT:
An evacuated envelope having a front wall encloses a plurality of electron beam guides. Extending across one end of the beam guides is a line cathode which generates a plurality of electron beams and directs the beams into the guides. A pair of parallel modulation electrodes is associated with each beam guide and is positioned with the cathode between them. Each modulation electrode partially overlaps the associated electron beam guide. A cathodoluminescent screen is on the front wall.
