Abstract
PURPOSE:To supply a large deflection current to a vertical deflection coil by mounting externally further an output circuit to a vertical deflection output circuit of IC configuration. CONSTITUTION:A TR 28 is turned on during the vertical period and the TR 30 is turned off and a capacitor C21 is charge up to a power voltage Vs. Moreover, during the blanking period, a TR 28 is turned off and a TR 30 is turned on, then a voltage at a terminal 3 goes to Vs and 2Vs voltage is applied to the power supply terminal 1. Thus, a large sized CRT is driven by mounting an output circuit 7 with a large rated output externally the IC circuit 6. In this case, a diode D10 is added to activate a pump-up circuit of the IC circuit 6 without any hindrance, then a sufficiently higher power voltage is supplied to the output circuit during the blanking period and the width of the vertical blanking period is made narrow sufficiently.
