ABSTRACT:
An apparatus for driving a display panel can execute quality image display. To allow discharge cells operating as pixels of the display panel to repeatedly perform sustain discharge, a fall period of a last sustain pulse of sustain pulses repeatedly applied to row electrodes includes a first voltage drop period in which a voltage value gently drops, a voltage constant period which follows the first voltage drop period and in which the voltage value remains constant for a predetermined period, and a second voltage drop period which follows the voltage constant period and in which the voltage value drops more gently than in the first voltage drop period.
