High-luminous-efficiency AC-plasma display panel using separate discharge mode in tiled sustain electrode structure

Abstract

The discharge characteristics of high-efficiency AC-plasma display panels (PDPs) using a separate discharge mode were investigated using both numerical simulation and experiments. New types of segmented sustain electrodes have been proposed in order to increase the luminous efficiency with low power consumption and without major changes in the manufacturing process. We have obtained the higher efficiency with a wider separation between the left-side and right-side discharges in a cell. This effect can be explained in that a wider gap between the tiles is beneficial because the discharge remains confined to the walls, thus efficiently exploiting the phosphor on the walls. The discharge images of an intensified charge-coupled device (ICCD) camera in a tiled sustain electrode structure support these results.
