Improvement of the Performance and Aging Characteristics of Color Plasma Displays by Using a Co-Evaporated Protecting Layer

Abstract

This work shows that the application of a MgO and MgF₂ co-evaporated protecting layer to a combination of transmissive and reflective phosphor type color PDPs improves the luminance and the luminous efficiency and the optimum composition of the co-evaporated layers is 24% MgO and 76% MgF₂. This work also confirms that the sustaining voltage and life of reflective phosphor type color PDPs with the co-evaporated protecting layer are almost the same as those with a MgO single protecting layer. The sustaining voltage of combination of transmissive and reflective phosphor type color PDPs, however, is higher than that of reflective phosphor type color PDPs. It is probable that sustaining voltage can be decreased by thinning the thickness of the phosphors.
