摘要:
A deflection yoke attached to a color cathode ray tube forming multiple electron beams arranged in line, and in particular a deflection yoke having convergence correction apparatus. Circuit components such as a plurality of resistors, variable resistors, and diodes are connected in parallel with vertical deflection coils. A part of a vertical deflection current flowing through the vertical deflection coils is diverted to the circuit components. Furthermore, the amount of the diverted current is made adjustable so that it will differ between a former part of a vertical deflection period and a latter part thereof. As a result, horizontal line misconvergence at upper and lower ends of the screen can be completely corrected.
