ABSTRACT:
A driving circuit suitable for driving a capacitive load such as an EL display panel is disclosed, which comprises a first power source terminal; a second power source terminal; an output terminal, with which a capacitive load is connected; a source side thyristor connected between the first power source terminal and the output terminal, and supplying current to the load; a sink side thyristor connected between the second power source terminal and the output terminal and drawing-out current from the load; and a control section connected between the first power source terminal and the second power source terminal and ON-OFF controlling the source side thyristor and the sink side thyristor through a circuit arrangement coupled between the control circuit and the gates of the thyristors.
