Abstract:
A method of driving a plasma display panel having a first substrate, first and second electrodes formed on the first substrate, each pair of the first and second electrodes extending in parallel with each other and corresponding to a display line, a second substrate facing the first substrate, third electrodes formed on one of the first and second substrates orthogonal to and electrically separated from the first and second electrodes, and discharge cells formed at intersections of the first and second electrodes and the third electrodes, said method comprising:in a reset period, producing a potential difference between the first and second electrodes and resulting reset discharges in the discharge cells to accumulate wall charges therein so that a potential difference among the wall charges achieves self-erase discharges and equalizes the distribution of charges among the discharge cells;in an addressing period, producing selective discharges with the second and third electrodes in selected ones of the discharge cells, in accordance with writing display data into the selected discharge cells;in a sustain discharge period, applying sustain discharge pulses to the first and second electrodes, enabling the selected discharge cells to discharge and emit light; andsetting the polarity of the potential difference between the first and second electrodes in the reset period to be opposite to the polarity of the potential difference between the first and second electrodes in the addressing period.
