Abstract
A flat type cathode ray tube. Electrode beams are vertically emitted from electron beam emitting sources along vertical scanning electrodes which have a strip-shaped configuration in horizontal direction and are insulated from each other and lined up in the vertical direction. The beams turn at a predetermined position toward a phosphor screen for vertically scanning and are horizontally focussed and deflected onto the phosphor screen by horizontal focussing and deflection electrodes.
