Abstract:
1. A method of driving a plasma display panel on which images are displayed of a video signal, said plasma display panel comprising a first substrate, a second substrate disposed facing said first substrate, a plurality of scanning electrodes that are disposed on a surface of said first substrate facing said second substrate and extend in a first direction, a plurality of common electrodes that extend parallel with said scanning electrodes on said surface facing said second substrate and are disposed alternately with said scanning electrodes, a plurality of data electrodes that are disposed on a surface of said second substrate facing said first substrate and extend in a second direction crossing said first direction, and display cells disposed at the respective intersections of pairs of said scanning electrode and said common electrode with said data electrodes, said method comprising the steps of: dividing one field corresponding to one image into a plurality of sub-fields; and arranging at least one second sub-field after a first sub-field of said plurality of sub-fields, wherein in said first sub-field, said method comprising: in said second sub-field, said method comprising the same steps as said third, fourth and fifth steps, wherein each of said fifth steps in said first and second sub-fields includes setting a potential difference between said scanning electrode and said common electrode to be smaller than a potential difference between said scanning electrode and said common electrode in each of said third steps in said first and second sub-fields, and said second step in said first sub-field includes setting a potential of said common electrode to be equal to a potential of said common electrode in said fifth step.
