Abstract:
1. A method of driving a plasma display apparatus comprising: supplying a first scan signal to a first scan electrode group of a plurality of scan electrode groups each including at least one scan electrode during an address period; supplying a second scan signal having a different voltage magnitude from a voltage magnitude of the first scan signal to a second scan electrode group of the plurality of scan electrode groups during the address period; and supplying a data signal corresponding to the first scan signal and the second scan signal to an address electrode, wherein the first scan signal or the second scan signal is supplied depending on scanning order of the plurality of scan electrodes during the address period, wherein when a temperature of the plasma display panel is higher than a critical temperature, the voltage magnitude of the first scan signal is smaller than the voltage magnitude of the second scan signal, wherein when a temperature of the plasma display panel is lower than a critical temperature, the voltage magnitude of the first scan signal is larger than the voltage magnitude of the second scan signal, and the first scan signal is applied prior to the second scan signal.
