  • Device for electron beam control in a cathode ray tube
    Patent number: 5189336
    Abstract: This invention enables the control of the electron beam position within a picture tube. Control is achieved by the use of a magnetized strip which is formed into a ring around the neck and secured by an adhesive film. In one implementation of this invention the strip has at least one end tapered in thickness for preventing an increase in thickness at the ring overlap. The strip ends are overlapped to provide a continuous ring of magnetic medium for optimum control capability.
