Planer Type Plasma Display as a Next Generation High-Efficiency PDP

Summary form only given. Low luminous efficiency is one of the major problems of a plasma display panel (PDP). The luminous efficiency of the state of the art PDP in the market remains below 2.5 lm/W. Here we have investigated and suggest the planar type plasma display as a new candidate for a next-generation high-efficiency PDP. Numerical simulation technique is used for the study. It is found that planar type PDP cell structure is getting more advantageous than conventional coplanar type PDP as the cell size is getting smaller. The calculated luminous efficiency of the suggested panel of 42" HD size is 3.9 lm/watt, with somewhat increased driving voltage. Usually, there is a trade-off between high-efficiency and low driving voltage. We have investigated this relation by changing Xe partial pressure and the gap between the electrodes. The method to reduce driving voltage while sustaining high-efficiency is also discussed.
