  • Patent number: 6911885
    Abstract: Disclosed is a deflection yoke to improve screen quality, including a coiling density adjustment groove formed along a vertical direction of a coil by way of increasing the coiling density at an arbitrary portion of the electric field at the internal side of the deflection coil. To this end, a winding frame is provided for winding coil around the deflection yoke, having a curvature of a designated shape at the center, in which the winding frame includes a wire position guide that projects as much as a designated width to a vertical direction of a coil to be wound around an arbitrary portion of the internal electric field for increasing a coiling density.
    Type: Grant
    Filed: February 27, 2002
    Date of Patent: June 28, 2005
    Assignee: Samsung Electro-Mechanics Co., Ltd.
    Inventors: Gyoung Su Kim, Young Gil Namgong, Cheong Moon Lee, Seok Hwan Hwang
  • Patent number: 6791252
    Abstract: Disclosed is a deflection yoke which is so configured that a coil separator and horizontal deflection coils have angular cross sectional shapes and a ferrite core and vertical deflection coils have circular cross sectional shapes to improve deflection sensitivity thereby reducing power consumption.
