Patent number: 7629754Abstract: A deflection yoke for a cathode ray tube improves assembly and productivity and enables effective control of magnetic field corrections during device processing. The deflection yoke includes a horizontal deflection coil located next to the outer circumference of a funnel to generate a horizontal magnetic field, and a vertical deflection coil installed at the outer circumference of the funnel to generate a vertical deflection magnetic field. The vertical deflection coil is insulated from the horizontal deflection coil. A ferrite core is located close to the vertical deflection coil to reduce the loss in the magnetic force generated from the horizontal and vertical deflection coils, and to enhance their magnetic efficiency. A correction unit is spaced apart from the horizontal deflection coil by a predetermined distance to correct a geometric distortion of the vertical and the horizontal deflection magnetic fields that is generated due to the vertical and horizontal deflection coils.Type: GrantFiled: February 6, 2006Date of Patent: December 8, 2009Assignee: Samsung SDI Co., Ltd.Inventors: Do-Nyun Kim, Ran-Ji Lee, Je-Wook Nam, Chang-Ryon Byon, Hoo-Deuk Kim, Moon-Jin Kim, Sang-Hoon Lee
