Abstract:
1. A plasma display apparatus comprising: a plasma display panel comprising a plurality of scan electrodes arranged to be driven in groups; and a scan driver for driving the plurality of scan electrode groups, and for distinguishing a level of a reset pulse supplied to at least one of the plurality of scan electrode groups from a level of a reset pulse supplied to one or more others ones of the plurality of scan electrode groups, wherein the scan driver comprises a first reset driver, a second reset driver, and a third reset driver and wherein the plurality of scan electrode groups comprise a first scan electrode group, a second scan electrode group, and a third scan electrode group, and wherein: the first reset pulse is supplied to the first scan electrode group in the setup period of the reset period of said one subfield in a first frame, and then the second reset pulse is supplied to the first scan electrode group in a setup period of a reset period of a subfield corresponding to said one subfield in a second frame, and then the third reset pulse is supplied to the first scan electrode group in a setup period of a reset period of a subfield corresponding to said one subfield in a third frame, the second reset pulse is supplied to the second scan electrode group in the setup period of the reset period of said one subfield in the first frame, and then the third reset pulse is supplied to the second scan electrode group in the setup period of the reset period of the subfield corresponding to said one subfield in the second frame, and then the first reset pulse is supplied to the second scan electrode group in the setup period of the reset period of the subfield corresponding to said one subfield in the third frame, and the third reset pulse is supplied to the third scan electrode group in the setup period of the reset period of said one subfield in the first frame, and then the first reset pulse is supplied to the third scan electrode group in the setup period of the reset period of the subfield corresponding to said one subfield in the second frame, and then the second reset pulse is supplied to the third scan electrode group in the setup period of the reset period of the subfield corresponding to said one subfield in the third frame.
