PROBLEM TO BE SOLVED: To provide a method for improving display characteristics of a plasma display panel. SOLUTION: A method and apparatus for driving the plasma display panel and improving the display characteristics through multi-discharge phenomenon is provided. The driving method is used for providing energy to light up at least a display unit in the plasma display panel and includes the following steps. Before providing any external energy, an energy recovery circuit provides internally stored energy so that the display unit has a first discharge through a resonance effect initiated by the internally stored energy. After the first discharge, external energy is provided to the display unit to trigger a second discharge. Thereafter, the energy recovery circuit stops providing internally stored energy to the display unit. Similarly, external energy to the display unit is also stopped. After the second discharge, the energy in the display unit is returned to the energy recovery circuit to serve as internally stored energy. COPYRIGHT: (C)2007,JPO&INPIT
