Abstract— In this study, the effects of diamond and AlN layers inserted beneath the phosphor layer of the rear plate of a PDP were investigated. The layers were formed via an osmotic‐pressure coating process. Macrocells and test panels were prepared to examine their effects on luminance and luminous efficacy. The results indicate that the layers primarily affect the glow‐discharge behavior and eventually enhance the luminous efficacy of the PDP, suggesting the possibile improvement in the performance of PDPs.

Abstract— In this study, the effects of barrier‐rib morphology on the luminance efficacy of PDPs were examined. Barrier ribs such as stripe, waffle, rectangular, honeycomb, SDR, and inverse SDR types were prepared using the capillary molding process. By using rear plates with such barrier ribs, the luminance and its efficacy were measured. The results demonstrated the feasibility of a capillary molding process in fabricating high‐efficacy PDP discharge cells.
