Abstract:
1. A plasma display apparatus, comprising: a plasma display panel comprising a scan electrode; and a driver configured to supply a reset signal including a ramp-up signal to the scan electrode during a reset period of a subfield, and a negative polarity scan voltage supplied from a negative polarity scan voltage source, which is different from a sustain voltage source that is to supply a sustain voltage, to the scan electrode during a address period after the reset period of the subfield, wherein: the driver includes a capacitor and a ramp-up generator having one end directly connected to the capacitor via a countercurrent interceptor and another end directly connected to a scan drive integrated circuit, the capacitor stores the negative polarity scan voltage supplied from the negative polarity scan voltage source, the ramp-up signal, which is generated by the ramp-up generator only using the negative polarity scan voltage stored in the capacitor and the sustain voltage supplied from the sustain voltage source, is applied to the scan electrode during the reset period, and the scan driver integrated circuit controls application of the ramp-up signal generated by the ramp-up generator and the negative polarity scan voltage supplied from the negative polarity scan voltage source to the scan electrode.
