Deflection yoke for correcting misconvergence

The deflection yoke of claim 2, wherein the misconvergence correcting means comprises:

• a first correcting part for generating the first magnetic field using the sawtooth current so as to enhance intensity of the barrel magnetic field to correct the misconvergence incurred when the light spot eradiated on a middle portion of the screen is deflected;
• a second correcting part for generating the second magnetic field opposite to the first magnetic field generated at the first correcting part and compensating for the first magnetic field and the second magnetic field so as to change the barrel magnetic field to the pinned magnetic field, the barrel magnetic field correcting misconvergence incurred when the light spot eradiated on an upper portion of the screen;
• and
• a current flow control part for controlling the current flow of the second correcting part, the current flow control part being turned on and off by the current inputted from the external power source.

A deflection yoke comprising:

• a first loop for generating a magnetic field using sawtooth current inputted from an external power source, the first loop being comprised of first to fourth coils and a first diode;
• and
• a second loop comprised of the first diode and a second diode,
• wherein the first and second coils are connected to each other in a series, and the third and fourth coils are connected to each other in a series but are connected to the first and second coils in parallel;
• the first diode has an anode connected to one end of the second coil, and a cathode commonly connected to one end of the fourth coil and an anode of the second diode;
• and
• the second diode has an anode commonly connected to one end of the second coil and the cathode of the first diode, and a cathode commonly connected to one end of the fourth coil and the anode of the first diode.
