Title:
TELEVISION IMAGE DISPLAY UNIT
Document Type and Number:
Japanese Patent JPS59134530
Kind Code:
A
Abstract:
A device for displaying television pictures comprising a display tube in the neck of which a gun system is present for emitting at least one electron beam towards a display screen, and comprising an electromagnetic deflection unit which is provided around the envelope of the display tube and which comprises a first deflection coil and a second deflection situated coaxially with respect to the first deflection coil, each having two diametrically oppositely located coil units. Each coil unit of the first deflection coil consists of two sub-coil units which are arranged axially with respect to each other, the sub-coil units which are present on the side of the gun system having a winding distribution for together generating a dipole deflection field in combination with a positive sixpole deflection field, the sub-coil units which are present on the side of the display screen having a winding distribution for together generating a dipole field in combination with a negative sixpole field on their sides remote from the display screen and a positive sixpole field on their sides facing the display screen.
