Patent ID: 7889155

Claim:
A plasma display apparatus comprising: a plasma display panel including a scan electrode; a sustain voltage supply unit that supplies a sustain voltage to the scan electrode; a scan reference voltage supply unit that supplies a scan reference voltage to the scan electrode; a scan reference voltage controller that is connected between the scan reference voltage supply unit and the scan electrode and includes a resistor changing the scan reference voltage into a reset signal with a predetermined slope; a voltage storing unit that is connected between the sustain voltage supply unit and the scan reference voltage supply unit and stores the scan reference voltage; and a driving signal output unit that controls an output of a voltage supplied to the scan electrode using a single switch, wherein a first terminal of the resistor of the scan reference voltage controller is directly connected to the scan reference voltage supply unit and a second terminal of the resistor of the scan reference voltage controller is directly connected to the scan electrode and the driving signal output unit, and a first terminal of the single switch of the driving signal output unit is directly connected to the scan electrode and the resistor of the scan reference voltage controller and a second terminal of the single switch of the driving signal output unit is directly connected to the voltage storing unit and the sustain voltage supply unit.
