12-7 Study on the Effective Secondary Electron Yield(γ') of a PDP Cathode

Abstract

In order to improve the discharge characteristics of a PDP, effective secondary electron yield(γ') of the cathode was studied. In the gas-discharge space, the secondary electron suffers the back diffusion due to collisions with gas molecules, resulting in considerable reduction of the yield. Thus calculated γ' in the typical PDP condition was 0.1〜0.5 times γ in the vacuum.
