Method of driving plasma display panel

A method of driving a plasma display panel in which a plurality of row electrode pairs and a plurality of column electrode form discharge cells at each of an intersections, and a fluorescent layer is provided in the discharge cells, the plasma display panel being gray-level driven in accordance with a video signal,

• the method comprising:
• executing, in each of the subfields when the display period of one field of the video signal is divided into a plurality of subfields which correspond to respective weightings, an address process which selectively sets the discharge cells to a lighting-on mode or lighting-off mode, and a maintained light emission process which applies a sustain pulse to the row electrodes which constitute the row electrode pairs;
• and
• applying an auxiliary pulse of the same polarity as that of the sustain pulse to the column electrodes in a first period which extends from after the application of a final scan pulse which is applied to one of each of the row electrodes of the row electrode pairs in the address process until the application of a leading sustain pulse, which is applied in the maintained light emission process, starts.

A method of driving a plasma display panel in which discharge cells on which a fluorescent layer including a fluorescent material is provided are formed at respective intersections between a plurality of row electrode pairs and a plurality of column electrode, the plasma display panel being driven in accordance with pixel data for each of the pixels based on a video signal,

• the method comprising:
• executing a write address process that sets the discharge cells to lighting-on mode by applying a pixel data pulse to the column electrodes selectively in one subfield when one frame display period of the video signal is divided into a plurality of subfields, and a sustain process which applies a sustain pulse to the row electrode pairs;
• executing, in the subfield which follows the one subfield, an erase address process which sets the discharge cells to lighting-off mode selectively and the sustain process;
• and
• taking, as an adjustment period, a period extending from time of the application of the final sustain pulse which is a sustain pulse that is applied last in the immediately preceding frame which is the one frame display period up until time of the application of the leading pixel data pulse which is a pixel data pulse that is applied first in the write address process of the one subfield of the subsequent frame which follows the immediately preceding frame, and making the adjustment period 1 msec (millisecond) or more.

• the method comprising:
• executing a write address process that sets the discharge cells to lighting-on mode by applying a pixel data pulse to the column electrodes selectively in one subfield when one frame display period of the video signal is divided into a plurality of subfields and a sustain process which subjects the discharge cells which have been set to the lighting-on mode to a sustain discharge by applying a sustain pulse to the row electrode pairs;
• executing an erase address process which sets the discharge cells to lighting-off mode selectively and the sustain process in the subfield which follows the one subfield;
• and
• taking, as an adjustment period, a period extending from the time of the application of the final light emission sustain pulse which is the sustain pulse which produces the sustain discharge last in the immediately preceding frame which is the first frame display period up until the time of the application of the leading pixel data pulse which is the pixel data pulse that is applied first in the write address process of the one subfield of the subsequent frame which follows the immediately preceding frame, and making the adjustment period 1 msec (millisecond) or more.
