摘要： In an apparatus and method for driving a plasma display including first and second electrode driving units for applying a driving waveform to first and second electrodes formed in parallel on a front panel, the second electrode driving unit applies a first bias voltage having a certain value not greater than a sustain voltage to the second electrode during a set-up period. That is, the second electrode driving unit does not apply a voltage of a ground level but applies a voltage having a certain value not greater than the sustain voltage, particularly, a voltage of a size of about half the sustain voltage, to reduce the potential difference between a scan electrode and a sustain electrode to thereby prevent occurrence of an erroneous discharge. Since the voltage of about half the sustain voltage can be implemented by using an output of an energy recovery unit, an additional device is not required, so its cost can be reduced, and in case of using the output of the energy recovery unit, since a free resonance waveform is generated, the possibility of preventing the erroneous discharge can be increased.
