Discharge analysis of high‐efficacy PDP with a luminous efficacy of 5 lm/W

Abstract

Abstract— The discharge mechanism concerning the width of the display electrodes in high‐Xe‐content gas mixtures to improve the luminous efficacy of PDPs has been researched. It was found that a luminous efficacy of 5 lm/W was realized for a high‐Xe‐content gas mixture and narrower display electrodes. For a high‐Xe‐content gas mixture, the luminous efficacy increases as the display electrode becomes narrower. This phenomenon was analyzed by observing the emission from a discharge cell. The observation data indicate that a high electron heating efficiency contributes to increased luminous efficacy along with narrow electrodes for a high‐Xe‐content gas mixture as well as high excitation efficiency.

Characteristics of a micro dielectric barrier discharge ignited by a cold cathode with high ion-induced secondary electron emission for plasma display panel

“…1, 2 The fundamental property of microdischarge in a PDP cell has been experimentally investigated for the last 10 years, [3][4][5][6][7][8][9][10][11][12] and the high Xe concentration of the discharge gas becomes one of the most promising approaches to improve the luminous efficiency. 13,14 But, the condition of high Xe partial pressure accompanies an increase in breakdown voltage, and the development of new cathode material is strongly required for low voltage PDP operation.…”

The effect of the cell size on the discharge characteristics of a plasma display panel

“…Many studies have been conducted with the aim of increasing the luminance efficiency of a plasma display panel (PDP) through the optimization of the discharge mode, by using a higher Xe gas content [1], changing the position of the bus electrode [2], using a new-type sustaining electrode [3], using a counter-type electrode configuration [4], separating the bus electrodes from the indium tin oxide (ITO) electrode lines [5], adapting an auxiliary electrode [6], or using a narrower ITO structure [7]. All these approaches are based on gas-discharge physics, in which the incremental number of electron creation and excitation is important for the luminance efficiency.…”

Simple Model of Bright-room Contrast Ratio Measurement System for Plasma Display Panels with Contrast Enhancement Film

“…Several studies have been conducted on the modeling and simulation of either the discharge characteristics for PDPs [8][9][10][11] or optical characteristics for liquid crystal displays adopting various optical films [12][13][14][15]. However, to the best of our knowledge, the modeling and simulation of the optical characteristics of PDPs, including the BRCR Simple Model of Bright-room Contrast Ratio Measurement System for … -Tae Won Beom et al performance, has not yet been reported.…”
