摘要： In a color picture tube apparatus, a deflection unit (27) is provided around a color picture tube (21) and a leakage magnetic (14) is generated from the deflection unit (27). A metal cover (32) made of aluminum, which covers an electrical power source is located in a space to which leakage magnetic field (14) is reached and a first opposition magnetic field is generated from the metal cover (32) due to the leakage magnetic field which produces an eddy current in the metal cover (32). A metal plate (34) made of a conductive and non-magnetic material is so located between the deflection unit (27) and the metal cover (32) as to be substantially perpendicular to the metal cover (32). Thus, a second opposition magnetic field is so generated from the metal plate (34) due to the leakage magnetic field as to substantially cancel the first opposition magnetic field.

摘要： A colour picture tube apparatus comprises a colour picture tube (11) including an envelope (15) having a phosphor screen (16) excited by a plurality of electron beams (18R, 18G, 18B), and deflection means (30) generating horizontal deflection field and barrel type vertical deflection field for the beams, including non-linear magnetic field correction means (40) generating an additional pin-cushion type magnetic field in the vertical field to have preferable convergence characteristics such that vertical direction coma errors can be appropriately corrected throughout every portion of the vertical axis on the screen, whereby high-definition colour images can be obtained thereon.
