ABSTRACT:
In an apparatus for driving a luminescent display panel, in a state in which scanning lines are sequentially scanned to drive and illuminate light-emitting elements, a voltage peak value arising in a scanning line in a non-scanning state is held by a capacitor through parasitic capacitance of the light-emitting element in a non-scanning state. On the basis of the voltage value held by the capacitor, a reverse bias voltage to be output from a reverse bias voltage generation circuit is controlled, and the voltage is supplied to the scanning lines.
