The low capacitance in the panel contributes to a reduction of power consumption in a Plasma Display Panel system. In this paper, the capacitances of the counter and coplanar electrode structures are compared on the basis of the measurement of discharge and displacement current. The sustain gap of the counter structure is wider than that of the coplanar structure under the same discharge volume. Furthermore, the sustain electrode area of the counter structure is smaller than that of the coplanar structure. Accordingly, the capacitance of the counter structure is lower than that of the coplanar structure for the same discharge volume and sustain gap.
