Abstract
In a convergence adjusting apparatus, there are generated waveform signals for adjustment, each level of which becomes zero at a plurality of adjustment points on a display except for one adjustment point. The levels of the waveform signals for adjustment are adjusted in accordance with convergence adjusting signals, and a convergence deflection yoke is supplied with the waveform signals having adjusted levels. In the convergence adjusting apparatus, only a beam spot at any adjustment point subjected to adjustment is moved when convergence adjustment is effected, without affecting adjustment for other adjustment points.
