Summary :

A method to characterise the wall voltage distribution in a three-electrode AC PDP cell is discussed. The method makes use of a firing voltage loop in a two-dimensional voltage plane. From this "fingerprint," data on the relative wall voltages as well as on the non-uniformity of the wall voltages can be inferred. The properties of the loop are explained using a simple numerical model based on field line tracing. The fingerprint method is applied to analyse ramp waveforms on the scan and data electrode of a surface discharge PDP. Many features of the measurements can be understood in terms of uniform wall voltage distributions on the dielectrics covering the electrodes. A more detailed analysis, however, shows that considerable wall voltage non-uniformities can exist, which play an important role in the firing behaviour of the cell.
