Title: PLASMA DISPLAY PANEL DRIVE CIRCUIT AND PLASMA DISPLAY APPARATUS
Abstract:
A drive circuit for driving a plasma display panel (PDP) includes a pulse voltage generation circuit (5101) that contains main switching elements disposed on the high voltage side and on the low voltage side, is operable to generate a pulse voltage by operating the main switching elements in accordance with an output voltage from a first power supply (V1) and apply the pulse voltage to a PDP scan electrode and sustain electrode, and a reset voltage generation circuit (52) operable to generate a reset voltage in accordance with an output voltage from a second power supply (V2) and apply it to the PDP. The pulse voltage generator circuit contains a first diode (D11) that prevents the voltage outputted by the reset voltage generation circuit from being applied backward to the first power supply and a first switching element (S11) connected to the first diode in parallel.
