55.4: Influence of He‐Ne‐Xe Gas Composition on Vacuum Ultraviolet Ray Spectra in Plasma Display Panel

Abstract

The vacuum ultra-violet (VUV) ray emission characteristics for Plasma Display Panels (PDP) were studied using various systems.In the 3-component (Xe-25%Ne-He bal.) systems, an increase in the pressure and Xe content contributed to an increase in the 147nm atomic emission, whereas above a certain point this decreased. In contrast, in the 2-component 4%Xe-Ne bal. System, the 147 nm atomic emission was saturated with an increase in pressure. Integrated intensities of 147nm, 172nm and the total were largely changed with different measuring conditions (V fixed and V sus ), with Xe content variation. With the increase of Xe content, when measured at V sus, atomic emission shows maximum value at 8 % while dimer emission linearly increased. On the other hand, atomic emission shows maximum value at 4 % in V fixed condition . Different 3-component gas compositions with the same Xe partial pressure showed nearly the same optical properties at a fixed applied voltage. In the case of Ne, the 147nm peak increased and the 172nm peak decreased with an increasing Ne content.
