Patent ID: 7952539

Claim:
A plasma display apparatus, comprising: a plasma display panel having a plurality of scan electrodes and sustain electrodes formed on a front substrate and a plurality of address electrodes formed on a rear substrate; and a driver that supplies driving signals to the plurality of electrodes, wherein the plasma display panel is driven with a unit frame which is divided into a plurality of subfields; wherein a reset signal supplied during a reset period of a first subfield of the plurality of subfields comprises a first rising period during which a voltage rises up to a first voltage, and a first sustain period during which the first voltage is sustained; wherein a reset signal supplied during a reset period of a second subfield of the plurality of subfields comprises a second rising period during which a voltage rises up to a second voltage lower than the first voltage, and a second sustain period during which the second voltage is sustained; wherein the second voltage is higher than a sustain voltage; and wherein a slope of the second rising period is in inverse proportion to an average picture level of a display screen and a length of the second sustain period is in inverse proportion to the average picture level of the display screen.
