Patent ID: 7649509

Claim:
A driving method for a plasma display device, wherein a frame is divided into a plurality of subfields, the plurality of subfields being divided into a first subfield group and a second subfield group and the plurality of subfields being driven, and wherein scan lines defining a plurality of discharge cells are divided into a first line group and a second line group, the first subfield group comprising first subfield having a first weight and a second subfield having a second weight that is greater than the first weight and is adjacent to the first weight in an order of weights of the first subfield group, the second subfield group comprising a third subfield having a third weight and a fourth subfield having a fourth weight that is greater than the third weight and is adjacent to the third weight in an order of weights of the second subfield group, the driving method comprising: resetting the plurality of discharge cells a first time during a first time period, the first time period comprising a single reset period; addressing discharge cells corresponding to the first line group of the plurality of discharge cells during a first address period of the first time period; after the first address period, generating a first sustain discharge during a first sustain period of the first time period; after the first sustain period, addressing discharge cells corresponding to the second line group of the plurality of discharge cells during a second address period of the first time period; after the second address period, generating a second sustain discharge during a second sustain period of the first time period; resetting the plurality of discharge cells during a second time period, the second time period comprising a single reset period; addressing the discharge cells corresponding to the second line group of the plurality of discharge cells during a third address period of the second time period, after the third address period, generating a third sustain discharge during a third sustain period of second time period; after the third sustain period, addressing the discharge cells corresponding to the first line group of the plurality of discharge cells during a fourth address period of the second time period; and after the fourth address period, generating a fourth sustain discharge during a fourth sustain period of the second time period.
