摘要： The present invention relates to a method of driving an AC-type plasma display panel and plasma display apparatus, in which differences between scan lines are reduced, so that it is advantageous in high-speed driving and it is stable, in which the power consumption is not concentrated on a specific period, so that a power circuit is easily designed, in which the degradation of phosphor and degradation of image quality, such as an afterimage, due to an increase in the temperature of a panel can be prevented, and in which an ability to display low gray scales is improved and pseudo contour noise is easily reduced. In the plasma display panel driving method, the image information has one or more frames each divided into one or more sub-fields used to display gray scales through combinations of the sub-fields. The sub-fields are each divided into one or more driving units T each having an address period, a sustain period and an erase period that are temporally separated. In the plasma display panel driving method, data for a corresponding sub-field is written during an address period in a first one of the driving units T constituting the sub-field. Data for the corresponding sub-field is erased during an erase period in a last one of the driving units T constituting the sub-field.
