CRT arrangement compensating misconvergence of side beams |
摘要 |
A color cathode-ray tube apparatus has a compensation mechanism for generating a magnetic field that compensates a change in a horizontal-deflection magnetic field due to a change in the temperature of horizontal-deflection coils. The compensation mechanism is formed of auxiliary coils to which a current is supplied in synchronism with horizontal deflection of electron beams, and a control element for controlling the current supplied to the auxiliary coils in accordance with a change in the temperature of the horizontal-deflection coils.
