Development of measurement technique of gamma coefficient for MgO film on PDPs
Details
The research and the development on a MgO film characteristics is very important for the development of recent AC-type Plasma Display Panels (PDPs). A γ coefficient is one of the MgO film characteristic which correlates to the ignition voltage or the luminous efficiency of PDPs. In this paper, we propose a new technique for γ coefficient evaluation on the MgO films using the pin-shaped electrode discharge for ion generation. And we describe the experimental results which include the correlation between the ignition voltage and the measured γ coefficient values, difference of the γ coefficient values by gas species or sample treatment before the measurement.
