P‐67: Luminance Improvements of PDP using Reflection Layers Formed via Osmotic Coating Process

Abstract

In this study, a reflection layer on rear plate of plasma display panel (PDP) was formed via osmotic coating process in an attempt to improve luminance efficiency of PDP. The processing parameters of the osmotic coating process which include coating solvent, swelling characteristics, and coating time were optimized to obtain uniform reflection layer on inside walls of discharge cell. The effect of TiO2 reflection layer thickness on luminance of the panel was investigated. Comparison with the panel without the layer showed that luminance and its efficacy could be improved by 50%.

Effects of diamond and AlN layers inserted beneath the phosphor layer on the discharge characteristics of PDPs

“…The enhanced improvement was also confirmed by other experiments. 6 These results suggest that the use of a reflection layer beneath the phosphor layer not only reflects the visible light, but also influences other phenomena that may affect the efficacy of discharge in the cells.…”
