35.4: Temperature Dependence of Exo‐electron Emission for AC PDP

Abstract

In this study, we attempted to understand the temperature dependence of statistical delay of ac-PDPs. Two theoretical models, Auger mechanism of thermal excitation and Tunneling model, were used to predict the temperature and time dependency of exo-electron currents. In the Auger mechanism model, a distributed source of trapped electrons was used. The theoretical prediction from the Auger model showed a significant discrepancy from the experimentally measured results from the panels with MgO nano-cube powder coating. The tunneling model seems to describe the exo-electron currents from MgO nano-cube powders better.
