Colour picture tube device in which YH misconvergence is corrected |
摘要 |
A group of an upper coma correction coil and an upper four-pole coil is positioned in opposition to a group of a lower coma correction coil and a lower four-pole coil, with respect to an electron beam. A first circuit is composed of a circuit in which the lower four-pole coil and a first diode are connected in series is connected in parallel to the upper coma correction coil. A second circuit is composed of a circuit in which the upper four-pole coil and a second diode are connected in series is connected in parallel to the lower coma correction coil. The first circuit and the second circuit connected in series compose a YH correction circuit. The first diode and the second diode are positioned so as to have opposite polarities. Vertical deflection current is diverted to the YH correction circuit. <IMAGE> |
