(54)	Plasma display aparatus and method of driving the same

(57) In a plasma display apparatus, the magnitudes of reset pulses are controlled or the widths of scan pulses in units of sub-fields, thereby improving contrast, preventing driving margins from deteriorating, stabilizing discharges and improving brightness. The weighted sub-fields need not be arranged in progressive orders of weight, but may be randomly arranged.
