Abstract
An erasing method and apparatus for a plasma display panel that is capable of minimizing spurious wall charges left after an erasing discharge. In the erasing method, an erasing signal taking a ramp waveform shape is applied to any one of first and second electrodes for alternately causing a sustain discharge. A voltage of said erasing signal is sustained at a voltage upon erasing discharge after the erasing discharge caused by said erasing signal.
