Picture display device.

摘要

Picture display device comprising an in-line colour display tube having an elongate display screen with a short axis and a long axis, which screen is provided on an inner surface, and a deflection system. The plane in which the undeflected electron beams are located is parallel to the short axis of the display screen. The deflection system comprises a first system of deflection coils for generating a substantially pincushion-shaped deflection field in the direction of the short axis of the display screen and a second system of deflection coils for generating a substantially barrel-shaped deflection field in the direction of the long axis of the display screen. The deflection system has terminals to be connected to a signal generator for scanning the display screen in a raster having a plurality of lines oriented along the short axis of the display screen.
