A one dimensional multi-species fluid model has been developed to analyze the operation of an ac plasma display panel (AC PDP) that is filled with a helium-xenon Penning mixture. The AC PDP is a promising candidate in the flat panel display industry especially for information displays having large screen areas. A PDP consists of a matrix of gas cells operating at pressures of several hundred Torr. In each cell a micro discharge is initiated using special driving circuitry that typically have address, sustain and erase pulse wave forms. The AC PDP has a memory characteristic which eliminates the need for a refresh pulse once a cell has been addressed. To ensure that a single sustain pulse can maintain a cell in the ON or OFF state, a large memory margin is essential. The model can be used for parametric studies to observe the effects of variations in pressure, gap width, and percentage of xenon on the first on and first off voltages, bi-stable margin and on xenon metastable and dimer populations. The authors present results of such parametric variations and comparisons with experiments.
