“…When Xe concentration was increased to 15%, the efficacy improvement was in the range of 100~130%. In summary, when CNTs were used as electron sources for dielectric barrier plasma discharge, we were able to improve both luminance and luminance efficacy of PDPs, which contravenes the general understanding where an increase in luminance of PDP typically leads to reduction in luminance efficacy [11]. The fact that luminance efficacy was increased more than that of luminance should be a direct result of reduced power consumption of the panel with the CNTs planting.…”

In order to increase the effective yield of secondary electron emission from MgO protective layer, we used carbon nanotubes (CNTs) as a supplementary electron source for plasma discharge of PDP. CNTs were planted on the surface of transparent dielectric layer and coated with MgO in order to induce field emission of electrons under electric field formed during operation of PDP. Luminance and luminance efficiency of the panel with the CNTs were increased significantly, demonstrating a possibility of hybrid PDPs.

This work has been devoted to a numerical and analytical calculus of the voltage breakdown in electrical discharge for several rare gases such as argon, krypton, neon, xenon and helium. It was performed using a fluid model 2D, which is based on the numerical solution of the two Boltzmann equations (equation of continuity and momentum), coupled to Poisson's equation to measure the breakdown voltage according to the product of the electrode spacing and the pressure. This study allowed a better comprehension of the physical phenomena occurring in the discharges. We, thus, developed a calculation, based on the empirically Paschen's law, allowing the determination of the breakdown voltage, which describes the transition from insulating gas to the conductive state. Paschen's curves of the different gases are plotted and a comparison between numerical and experimental as well as analytical results is also presented and analyzed.

“…Considering the energy balance in PDP discharge, the discharge efficiency can be mainly divided into the electron-heating efficiency, the Xe excitation efficiency and the VUV-radiation efficiency. 11 The electron-heating efficiency is defined as the fraction of the total discharge power energy which is used for the electron heating. The Xe excitation efficiency is the ratio of the energy that is used for Xe excitation to the energy of electron heating.…”

Abstract— The high‐Xe‐concentration and high‐γ (ion‐induced secondary‐electron emission coefficient) protective layer have been diagnosed from both experimentation and simulation. The experimental results show that there is a great increase in luminance and luminous efficacy, while the breakdown voltage decreases in the high‐Xe and high‐γ discharge. In the high‐Xe discharge, the great increase in VUV radiation mainly results from an increase in excimer VUV emission. The application of high‐Xe concentration can greatly increase the luminous efficacy, while the high‐γ protective layer can promote it further. Considering that the total discharge efficiency can be divided into the electron heating efficiency, the Xe excitation efficiency, and the VUV radiation efficiency, both the electron heating efficiency and Xe excitation efficiency increased for a high‐Xe discharge; while for a high‐γ discharge, the increase in electron heating efficiency contributes to the improvement in discharge efficiency.
