Abstract

We report the enhanced secondary electron emission yield and reduced firing voltage of ac-PDPs by using vapour chopped MgO thin film as protective layer. MgO thin films have been prepared by thermal oxidation (in air) of vacuum evaporated magnesium films at 573, 623 and 673 K. SEE yield showed variation with oxidation temperature. The use of vapour chopping technique approach was aimed to improve the SEE yield. The reduced surface roughness and improved SEE yield by use of vapour chopping technique supports the better performance and greater lifetime of the panel assisting to reduce the operational costs.
