PURPOSE: A plasma display device is provided to control the magnitude of a sustain bias voltage according to a panel. CONSTITUTION: A plasma display panel includes a scan electrode. A reference voltage generator(210) generates a reference voltage falling from a first voltage and a second voltage by receiving a mode signal from the outside. A feedback unit(220) outputs a control signal by comparing the reference voltage with the feedback voltage. A voltage detector(230) supplies the feedback voltage to the feedback unit by detecting the voltage of the sustain electrode and forming the feedback voltage. A signal supply unit(240) supplies a first setup signal rising to a first setup voltage to a scan electrode by corresponding to the reference voltage according to the control signal. A voltage controller(250) receives the first voltage from the outside and controls the magnitude of the second voltage of the reference voltage. |
