Discharge Efficiency Improvement in PDP Cell via a 1-D PIC/MCC Method

The aim of this paper is to study the different ways to optimize plasma display panel (PDP)´s efficiency. A particle-in-cell (PIC) model was developed. The major characteristics of a single discharge calculated by this model are compared to those obtained by the fluid model. The PIC model, although it is high cost in time, remains an efficient tool to understand the fundamental discharge physics of the PDP. Even there is some difference as in the delay time and ionization, the discharge behaviors have been correctly described, as well as the energy balance. The results indicate that the energy deposition and the xenon excitation efficiency are influenced by many parameters as the gas mixture composition, gas pressure, applied voltage, and the gap length. The values of the xenon excitation efficiency predicted by the model for a total gas pressure of 750 torr is in the order of 15% at low discharge gap (50) and of 20% at a long gap (200 ).
