Abstract
A display panel driving apparatus which reduces a peak value of a voltage/current upon charging or discharging of discharging cells on a display panel. The apparatus has a pulse generating part for supplying a driving pulse to a capacitive light-emitting device arranged in each of crossing positions of a plurality of row electrode pairs and column electrodes on the display panel of the display panel driving apparatus. The pulse generating circuit includes a charge/discharge resonance circuit for executing charging and discharging to the capacitive light-emitting devices through an inductor, and a harmonic multiplexing circuit for multiplexing a harmonic current having a harmonic frequency of a resonance frequency of the charge/discharge resonance circuit to a charge/discharge current by the charge/discharge resonance circuit.
