Effect of He-Xe mixtures on excitation efficiency in PDP and comparison of Ne-Xe mixtures with computational method

Each cell in a plasma display panel (PDP) is activated by discharge of a mixture of rare gases such as He or Ne and the excitation of a main gas such as Xe. Due to the limitation in increasing Xe partial pressure, the luminous efficiency of PDP is usually lower than that of Cathode Ray Tube (CRT). In this paper we have investigated the effect of mixture composition on the micro discharge cell efficiency. We show that the excitation efficiency and luminous efficiency in He-Xe mixtures is lower than that of Ne-Xe mixtures. We find that adding a small amount of Ar in a Ne-Xe mixture increases cell efficiency, while for He-Xe mixtures cell efficiency is reduced.
