A one dimensional model of the discharge occurring in the alternating current plasma display panel cell is developed. The model includes a continuity equation for each species and Poisson’s equation. The space and time variation of the charge particle densities, electric potential, electric field and surface charge densities are described. Results are presented in a 90% Neon-10% Xenon gas mixture, for a gap length of 100 μm and a gas pressure of 560 Torr at ambient temperature. Both single pulse and multipulse simulation is done. The duration of discharge pulse is taken to be 2µs or 4µs, depending on the applied voltage. The code shows a reasonable good agreement with the published literature. The simulation shows that considering neutral density as fixed or variable does not affect the results. Voltage transfer curves and margin obtained with this model are presented. In case of multipulse simulation, the results are found to be a function of sustain voltage and not of firing voltage.
