DEFLECTING DEVICE OF VIDEO DISPLAY APPARATUS

摘要

PURPOSE: To reduce the influence on a deflecting current by reducing a change in the resistance of a deflecting circuit due to a temperature change. CONSTITUTION: In a DC coupled type vertical deflecting circuit, an input tooth- shaped wave signal is connected to an inversion input of a vertical deflecting amplifier 11a through 1st resistance circuit networks R40, R50 and R60. A DC voltage is connected to a 2nd input of this amplifier through 2nd resistance circuit networks R10, R20 and R30 to prevent the DC signal component from affecting the deflecting current. In order to execute a temperature compensation, the corresponding resistances having the same values to the respective resistances included in the 1st resistance circuit networks are included in the 2nd resistance circuit networks.
