Abstract
A circuit configuration for realizing high impedance in an address drive circuit is provided in order to reduce the number of recovery switches without reducing power recovery efficiency. A mechanism for realizing the high impedance in an address drive circuit during a sustain period of a plasma display panel is provided. By achieving the high impedance, capacitance coupling between an X electrode and an address electrode and between a Y electrode and an address electrode can be cancelled, and a power recovery circuit can be simplified without reducing the power recovery efficiency.
