Patent ID: 7796096

Claim:
A plasma display apparatus comprising: a plasma display panel having a plurality of discharge cells, and time-division components driven by dividing a unit frame into a plurality of subfields; and a driver for supplying a reset signal for initializing the plurality of discharge cells to a scan electrode of the panel in a reset period, wherein the driver supplies rising setup signals to the scan electrode in reset periods of the plurality of subfields, and an average slope of the rising setup signal supplied in a first subfield among the plurality of subfields is different from an average slope of the rising setup signal supplied in a second subfield, wherein the rising setup signal comprises two or more variation periods for which the setup signal rises with a first slope, and the rising setup signal comprises two or more sustain periods for sustaining a predetermined voltage between two adjacent variation periods among the variation periods, wherein a time duration of the two or more sustain periods for sustaining a predetermined voltage between two adjacent variation periods among the variations periods are the same in the rising setup signal supplied in the plurality of subfields, wherein the first slope of the two or more variation periods are the same in the rising setup signal supplied in the plurality of subfields, and wherein the time duration of the two or more sustain periods for sustaining a predetermined voltage between two adjacent variation periods among the variations periods of the rising setup signal supplied in a first subfield is different from a time duration of the two or more sustain periods of the rising setup signal supplied in a second subfield.
