20100214197CAPACITIVE-LOAD DRIVE DEVICE AND PDP DISPLAY APPARATUS - In a row-electrode drive circuit of a PDP display device, an N-channel MOS low-side transistor of an output section is in an ON state while a light emission of a capacitive load is sustained. Now, if power to a driver section is lost due to, for example, a disconnection of a line from an external power supply to a low-voltage power terminal, this loss of power is detected by a detection section, and a current path via a parasitic diode of a P-channel MOS transistor, which has turned off, in the driver section to the low-voltage power terminal is interrupted. As a result, the N-channel MOS low-side transistor of the output section has the charged electric charge of the capacitive load stored in a parasitic capacity between its drain and gate, so maintains the ON state. Therefore, even when power to the driver section is lost due to, for example, a disconnection of the line while a light emission of the capacitive load is sustained, a case where the low-side transistor of the output section turns off and breaks down is prevented.08-26-2010
