PLASMA DISPLAY PANEL DRIVE METHOD AND PLASMA DISPLAY DEVICE

摘要

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 a 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 where the write discharges are induced. 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 capacitor of a display electrode pair with an inductor and a clamp section for clamping the voltage of the sustaining pulses to a predetermined voltage. The repetition period of the sustaining pulse can be set according to the average luminance level of the image signal.
