ABSTRACT:
A television display arrangement includes a kinescope comprising a viewing screen, an in-line electron beam gun assembly for producing a plurality of electron beams and an envelope defining a neck, at one end of which the electron gun assembly is mounted. A deflection yoke is associated with the kinescope for producing astigmatic deflection fields for substantially converging the beams at all points on the viewing screen. The astigmatic fields have balanced nonuniformity functions with low peak excursions for reducing the sensitivity of the beam convergence to the position of the yoke relative to the electron beams, by which relative movement between the yoke and the kinescope does not substantially affect the convergence.
