ABSTRACT:
A strip or sheath-type beam bender providing purity and static convergence correction for an in-line color kinescope further includes a pair of oppositely polarized magnetic regions or zones on opposite sides of the kinescope neck and aligned with a plane passing through the horizontal beam axis in order to provide vertical beam movement. In order to conserve material, the beam movement zones may be located between purity correcting magnetized zones in the same longitudinal plane of the beam bender.
