摘要： A technique which relates to discharge in sustain operation of a PDP device and a driving waveform thereof, and which can improve luminous efficiency to achieve stability while reducing a possibility of failure of discharge is provided. In a generating operation of a sustain pulse in a sustain pulse generating circuit, after LU-ON (t1 to t2), a voltage applied on electrodes is raised up to a sufficiently-high voltage, namely, a sustain voltage according to an ON state of a CU circuit (t2 to t3), and discharge is started, CU is once turned OFF (t3), then a first discharge peak is formed (t11). Thereafter, CU is turned ON again before discharge is converged (t12) to raise a voltage value and form a second discharge peak (t14). Since a voltage Vi to start discharge is sufficiently high, a possibility of discharge failure is suppressed, and an effect of improvement in luminous efficiency is not ruined.
