Patent ID: 7688285

Claim:
A driving method of a plasma display apparatus having a scan electrode and an address electrode, the method comprising: supplying a falling voltage to the scan electrode during a first time so as to form a scan signal in an address period; supplying a scan voltage sustained during a second time after the first time to the scan electrode so as to form the scan signal in the address period; and supplying a rising voltage to the scan electrode during a third time after the second time so as to form the scan signal in the address period, wherein at least one of the first time and the third time is from 20 ns to 150 ns, wherein the plasma display apparatus includes a plurality of scan electrode groups, and wherein each of the plurality of scan electrode groups includes one or more scan electrodes, a first time of a scan signal supplied to at least one of the plurality of scan electrode groups is different from a first time of a scan signal supplied to remaining ones of the plurality of scan electrode groups, or a third time of a scan signal supplied to at least one of the plurality of scan electrode groups is different from a third time of a scan signal supplied to remaining ones of the plurality of scan electrode groups.
