ABSTRACT:
A picture display device adapted for use in a projection color television receiver and comprising a monochrome display tube provided with a line deflection coil and a field deflection coil arranged contiguously in the direction of the tube axis, the line deflection coil being closer to the display screen of the picture tube. A convergence correction coil system is provided including a first convergence correction coil arranged coaxially with respect to the line deflection coil, one of such coils extending within the other, the first convergence correction coil generating a magnetic field at right angles to that produced by the line deflection coil. A second convergence correction coil is arranged coaxially with respect to the field deflection coil, one of such coils extending within the other, the second convergence correction coil generating a magnetic field at right angles to that produced by the field deflection coil. Crosstalk between the associated convergence correction coils and deflection coils is thereby minimized.
