Abstract: An energy recovery circuit of a plasma display panel is disclosed, which can drive the sustain electrode of the plasma display panel during the sustain period. The energy recovery circuit includes a voltage source which can store electrical energy, a first channel for raising the voltage of the sustain electrode to high potential, a second channel for pulling the voltage of the sustain electrode down to ground, and other auxiliary circuits. When the first channel is turned on, the voltage source can transmit electrical energy to the sustain electrode. When the second channel is turned on, the voltage source retrieves the electrical energy from the sustain electrode. Thereby the sustain electrode is driven between high potential and ground. Moreover, the first channel and the second channel can share a part of common channel.
