Investigation into plasma display panel discharge cells has developed over the last few years and has given researchers an insight into luminance efficiency. This paper discusses the effect of both the area size of the microcell discharge and phosphor on luminous efficiency. Simulation results show that by creating regular or irregular nano scale holes increases areal density of phosphors. However, the optical property of phosphor in nano scale has shown to be changed. These two advantages lead to an increase in luminous efficiency by 14 per cent compared with the conventional plasma display panel cell.
