A Study of the New Penning Gas Mixture, He-Ne-Xe-Kr-Ar, for the Improvement of the Luminous Efficiency in AC Plasma Display Panel

Abstract

Alternative Current Plasma Display Panel(AC-PDP) has been the most promising one next generation Flat Panel Display (FPD) device, and has been regarded as a good candidate for the large-sized, wall hanging multimedia display. However, the demerit of AC-PDP is low luminance and the luminous efficiency. The improvement of the luminance and the luminous efficiency is the one of the most important parts in the AC-PDP. Especially, Penning effect has influenced on the improvement of the luminance and the luminous efficiency. It is dependent on the species and the partial pressure of the Penning gases. We investigated the Penning effect in mixture gas, He(70%)-Ne(27%)-Xe(3%)-Kr(0.005%)Ar(0.005-0.1%) to improve the luminance and the luminous efficiency in AC-PDP. When a small amount of Kr(0.005%) and Ar(0.005-0.1%) were added to He-Ne-Xe, the luminance increases for 8%, the wall charge increases for 18 %, and the luminous efficiency increases for 12 % at 400 Torr.
