Electro-optical characteristics in accordance with dielectric thickness of AC-PDP

Summary form only given, as follows. The improvement of luminance and luminous efficiency is the one of the most important part in AC-PDP. To achieve high luminance and luminous efficiency, we make an experiment on electro-optical characteristics in accordance with the dielectric thickness of AC-PDP. The wall voltages play an important role in lowering the sustaining voltage through wall charges accumulated on the dielectric surface in AC-PDP. The wall charges and voltages, as well as capacitances, are experimentally measured in terms of the dielectric thickness, whose thickness is ranged from 20 /spl mu/m to 50 /spl mu/m. We have developed a simple method to measure the wall charges and voltages resulting from the measurements of all capacitances in AC-PDP. These values are based on charge-voltage (Q-V) characteristic curves before and after the discharge, along with the voltage margin relation to the wall voltage and dielectric-gap voltage induced by wall charge. To find out optimal condition of dielectric thickness in AC-PDP, we make an experiment in the variety of dielectric layer thickness.
