Abstract
Improved plasma displays utilize electrodes including low electron affinity (LEA) materials such as diamond. In dc displays the LEA materials are disposed on the cathode. In ac displays the LEA materials are disposed on the dielectric layers of both electrodes. The improved displays exhibit reduced operating voltage, higher resolution, and enhanced robustness.
