Plasma display apparatus and method of driving the plasma display apparatus

A plasma display apparatus in which one field comprises plural subfields having a reset period followed by an address period and a sustain period, the plasma display apparatus displaying by controlling lighting of subfields, and comprising:

• a plasma display panel in which plural first electrodes and plural second electrodes are arranged adjacently and plural third electrodes are arranged to cross the plural first and second electrodes;
• a first electrode drive circuit driving the first electrodes;
• a second electrode drive circuit driving the second electrodes;
• a third electrode drive circuit driving the third electrodes, wherein:
• the second electrode drive circuit comprises:
• a waveform generating circuit generating a slope-shaped waveform in which a value of an applied voltage has a predetermined slope and increases with time during the reset period;
• and
• a voltage control circuit controlling start timing and termination timing of the slope-shaped waveform, and wherein:
• the voltage control circuit controls a final voltage value in the reset period reached by the slope-shaped waveform so that the final voltage value differs in at least two of the plural subfields of a given field.
