Abstract
The present invention relates to a plasma display apparatus and driving method of the same. Since wall charges are remained without performing an additional erasing discharge after the sustain period is terminated and before the initiation of the reset period, the set up discharge can be generated with a small voltage during the reset period to obtain the margin of the driving voltage. In particular, since the highest voltage of the reset period during other subfields is lower than the highest voltage of the reset period of a subfield implementing a low gray scale, with inducing the half discharge before the set up discharge in other subfields, the set up discharge can be generated with a low voltage to improve the contrast due to the luminous output reduction.
