Abstract

Here is presented the measurement on SrO- and SrCaO-PDP operated at lower voltage. SrO- and SrCaO-PDP attain high luminous efficacy at low voltage, where the breakdown voltage is 30 % lower than that of the ordinary MgO-PDP. A one-dimensional fluid model is applied for the simulation of PDP discharge. High VUV radiation efficiency is confirmed at high ${\gamma}_i$ and both low and high $V_s$ as in the experiment. Discharge analysis in simulation also shows that the high ${\gamma}_i$ protective layer leads to high plasma density especially near the cathode electrode, being responsible for high efficiency.
