Abstract:
1. A plasma display apparatus, comprising: a plasma display panel comprising a first electrode and a second electrode; a first energy recovery unit supplying the first energy to the plasma display panel through the first electrode with resonance or recovering the first energy from the plasma display panel through the first electrode with resonance; a first positive voltage supply unit supplying a first positive voltage to the first electrode after the first energy is supplied; a first negative voltage supply unit supplying a first negative voltage to the first electrode while the first energy is recovered or after the first energy is recovered; a second energy recovery unit supplying a second energy to the plasma display panel through the second electrode with resonance or recovering the second energy from the plasma display panel through the second electrode with resonance; a second positive voltage supply unit supplying a second positive voltage to the second electrode after the second energy is supplied; and a second negative voltage supply unit supplying the second negative voltage to the second electrode while the second energy is recovered or after the second energy is recovered, wherein the first negative voltage supply unit comprises a first negative voltage supply switch having a first gate terminal, the first gate terminal being connected to a first variable resistor and operating in an active area, and wherein the second negative voltage supply unit comprises a second negative voltage supply switch having a second gate terminal, the second gate terminal being connected to a second variable resistor and operating in an active area.
