发明名称 Cathode ray tube having degaussing coil for minimizing variations in landing of electron beam
摘要 A cathode ray tube includes a tube having a panel, a funnel, and a neck, a color selection apparatus mounted to the panel within the tube, an inner shield connected to the color selection apparatus. The inner shield includes a plurality of side walls that form a center opening through which electron beams pass, and at least one degaussing coil mounted at outer surface of the tube. The degaussing coil includes a first coil mounted toward the panel, a second coil mounted toward the neck, and a third coil connected to ends of the first coil and the second coil to interconnect the first coil and the second coil. The second coil is mounted on the tube in a state substantially overlapping distal edge portions of the side walls of the inner shield on which the second coil is mounted.
