Abstract:
A method of driving a plasma display panel having a plurality of scan electrodes aligned in a row direction, a plurality of data electrodes aligned in a column direction, and a plurality of sustain electrodes formed parallel to said scan electrodes and each of said sustain electrodes formed as a pair with a respective scan electrode, comprising:ON/OFF controlling display data by scan pulses applied to said scan electrodes and data pulses applied to said data electrodes in each of a plurality of sub-fields into which a unit image display period is divided; and effecting sustain discharge between said scan electrodes and sustain electrodes parallel to said scan electrodes in only those cells in which display data are ON following ON/OFF control of display data, wherein a sustain discharge period of at least one sub-field comprises a divided sustain discharge period comprising a plurality of sub-sustain discharge periods, and wherein in said divided sustain discharge period, sustain discharge pulses are applied to said sustain electrodes and said scan electrodes at a first frequency in a first sub-sustain discharge period and at a second frequency that is lower than said first frequency in a last sub-sustain discharge period.
