Abstract
A plasma display apparatus and method of driving the same is disclosed. The plasma display apparatus includes a calculation unit for calculating an average picture level of an input picture, a sub-field mapping unit for mapping data of the input picture to a first sub-field group and a second sub-field group, and a controller for controlling a time range between the data mapped to the first sub-field group and the data mapped to the second sub-field group according to the average picture level. If the average picture level is calculated at a first level, a generating time point of the data mapped to the second sub-field group is controlled to be at a first starting time point. If the average picture level is calculated at a second level higher than the first level, the generating time point of the data mapped to the second sub-field group is controlled to be at a second starting time point later than the first starting time point. If the average picture level is calculated at a third level higher than the second level, the generating time point of the data mapped to the second sub-filed group is controlled to be at a third starting time point earlier than the second starting time point.
