Patent ID: 7724213

Claim:
A plasma display device including a plasma display panel having a plurality of row electrode pairs and a plurality of column electrodes arranged to intersect with the row electrode pairs so as to form a display cell at each intersection thereof, the plasma display device displaying an image by configuring a plurality of subfields within a unit display period of an input video signal, each of the subfields including an address period and a sustain period, the plasma display device comprising: a magnesium oxide layer formed in each of the display cells; addressing means for selectively generating address discharge in each of the display cells in accordance with pixel data based on the video signal in the address period; and sustaining means for repeatedly applying sustain pulses between row electrodes configuring the row electrode pairs in the sustain period, wherein a rear edge part of the sustain pulse applied at the end of the sustain period of each of the subfields is formed by a first section in which a voltage value slowly changes from a peak voltage value of the sustain pulse to a predetermined first voltage value, a second section in which the first voltage value is maintained for a predetermined period, and a third section in which the voltage value slowly changes from the first voltage value to a second voltage value having a polarity different from that of the first voltage value.
