Abstract:
1. A method of driving a plasma display panel in which one field has a plurality of sub-fields and each of the sub-fields includes a setup period for generating initializing discharge in discharge cells, an address period for generating address discharge in the discharge cells, and a sustain period for generating sustain discharge in the discharge cells having generated the address discharge therein, and the plasma display panel includes a thermal sensor, the method comprising: estimating a lowest temperature and a highest temperature of the plasma display panel, according to a temperature detected by the thermal sensor; and selecting one driving mode from a plurality of driving modes based on the estimated lowest temperature and the estimated highest temperature, the plurality of driving modes have at least one different operation in the setup period, each driving mode includes sub-fields having an all-cell initializing operation to initialize discharge in all of the discharge cells in the setup period, and the at least one different operation includes driving the sub-fields having the all-cell initializing operation with a different maximum voltage or the at least one different operation includes driving a different number of the sub-fields having the all-cell initializing operation with the different maximum voltage in the setup period;
