Patent ID: 7834820

Claim:
A plasma display device for displaying an image on a plasma display panel in accordance with an input video signal, said plasma display panel having a plurality of row electrode pairs, and a plurality of column electrodes intersecting with said plurality of row electrode pairs, so as to form display cells at the intersections, respectively, and a display period for one field of the input video signal being configured of a plurality of subfields each formed of an address period and a sustain period for the image display, said plasma display device comprising: an addressing portion which selectively generates address discharge in each of said display cells in accordance with pixel data based on the video signal in the address period; and a sustaining portion which applies a sustain pulse between row electrodes forming each of said row electrode pairs in said sustain period; wherein said sustaining portion allows to make longer a leading period of each sustain pulse belonging to a first group including at least a sustain pulse to be applied secondly in the sustain period of each of the subfields as compared to a leading period of each sustain pulse belonging to another group including at least one sustain pulse to be applied thirdly or later.
