Abstract

The discharge-time lag in an ac plasma display panel was studied and the discharge phenomena in the cells were considered. As a result, it was confirmed that time lag characteristics are unique in ac-driven capacitively coupled discharge elements and that such characteristics have a decisive effect on the dynamic characteristics. It was further clarified that the secondary emission coefficient γ of the protection layer determines the time lag characteristics and it is an important determining factor of the dynamic characteristics. As a result of the study of the effect of γ, it was possible to confirm that high γ leads to high performance and, accordingly, MgO is appropriate as protection-layer material.
