Abstract

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.

Description

technical field [0001] The present invention relates to a driving method and a plasma display device for a plasma display panel used in a wall-mounted television or a large monitor. Background technique [0002] A typical AC surface discharge panel as a plasma display panel (hereinafter simply referred to as a "panel") has a plurality of discharge cells formed between a front panel and a rear panel that are arranged to face each other. In the front panel, a plurality of display electrode pairs consisting of a pair of scan electrodes and sustain electrodes are formed parallel to each other on a front glass substrate, and a dielectric layer and a protective layer are formed to cover these display electrode pairs. The back panel is respectively formed with a plurality of parallel data electrodes, a dielectric layer covering these data electrodes, and a plurality of barrier ribs parallel to the data electrodes on the dielectric layer, and formed on the surface of the dielectric ...
