ABSTRACT:
An improved lateral convergence deflection system for a delta-gun shadow mask color CRT includes first, second and third lateral convergence coils mounted on the CRT neck radially outward from the paths of the electron beams from the three guns. The coils are connected in series electrically, and are of suitable strength and orientation to provide a substantially unidirectional, vertical field in the path of one (e.g., the blue) beam, and field nulls in the paths of the other two (e.g. the red and green beams). By varying the current passed through the coil by a convergence drive amplifier, the blue beam may be shifted laterally without producing any substantial movement of the other two beams.
