PLASMA DISPLAY DEVICE AND PLASMA DISPLAY PANEL DRIVE METHOD

A plasma display panel drive method for increasing the luminance of the panel and enabling reduction of power consumption and a plasma display device are provided. One field is composed of a plurality of sub-fields including a write period during which write electric discharge is selectively induced in discharge cells and a sustaining period during which sustaining pulses the number of which corresponds to the luminance weight are applied to induce sustained discharges in the discharge cells. The plasma display device has a sustaining pulse generating circuit composed of a power recovering section for inducing the rise and fall of each sustaining pulse by resonating the electrode-to-electrode capacitance of a display electrode pair composed of a scan electrode and the sustain electrode with an inductor and a clamp section for clamping the voltage of the sustaining pulses to a predetermined voltage. The sustaining pulse for inducing the second last sustained discharge by means of the sustaining pulse generating circuit is not the one whose repetition period is the shortest one.
