Abstract: A convergence correction system is disclosed for digitally controlling the convergence correction signals applied to the convergence correction coils of a color CRT. The convergence correction signals correspond to a plurality of segments defined for the phosphor face of the CRT, so as to produce the convergence of the associated electron beams at the phosphor triads within the individual segments. The system provides for the independent adjustment of the convergence of each electron beam within each of the four quadrants of the phosphor face, independent of the adjustments for the convergence of the other electron beams. The system further provides for the use of only one convergence correction coil for each associated electron beam.
