Abstract
A plasma display panel that is adapted to reduce the power consumption and the EMI and to prolong a life thereof. In the panel, common terminals are used in first and second sustain electrode lines arranged on a pixel cell matrix to keep a discharge in pixel cells. The common terminals simultaneously apply a driving signal to each of two sustain electrode lines, thereby charging electric charges in next line pixel cells during maintaining the discharge at one line pixel cells.
