We performed a discharge analysis on ac plasma display panel through the numerical simulation of the EF (Energy Fluid) model using the electron's energy equation. When it is compared to the results of commonly used LFA (Local Field Approximation) model, there is a clear difference in the spatiotemporal distribution of Xe excited species. In particular, the experimentally observed striation phenomena in the anode region could be observed in EF model and the occurrence of the striation was attributed to the ionization and excitation instability due to the streaming electrons in the anode region plasma.

The sustain driver for AC plasma display panel should provide alternating high voltage pulses to ignite plasma and recover the energy discharged from the intrinsic capacitance between the scanning and sustaining electrodes inside the panel. In this paper, an efficient sustain circuit employing boost-up function is proposed to achieve a faster rise-time in order to be suitable to widely used the address display period separated (ADS) driving method. The proposed circuit improves the recovery efficiency, regardless of the variation of the panel capacitance. The principle of operation, features, and simulated results are illustrated and verified on a 7.5-inch diagonal panel at 200 [kHz] operating frequency based on experimental prototype.

A new electrode structure in a plasma display panel was designed in a way to increase the bright room contrast ratio (BRCR). The area of the black matrix pattern to get a low reflection from the panel surface was enlarged using the new electrode design concept. The electrical characteristics such as firing voltage, voltage margin and power consumption were measured. The luminance of the panel was measured and the luminous efficiency was calculated. It was found that the new electrode structure was very effective to enhance the BRCR.

We have investigated the micro-discharge in plasma display panel using 2 dimensional 2 fluid MHD equations. Plasma display utilizes the physical phenomena of the normal glow or abnormal glow and is considered to be able to provide the largest display area among various flat panel. 2 fluid, 2 dimensional Magneto-Hydro-Dynamic equations are applied to Computational field of 100${\times}$800${\mu}m^2$. Time varing glows and after-glows were investigated for 11 $\mu$sec. We obtained the distribution of the microscopic variables such as the density, temperature, velocity of Ne+Ar0.1% gas plasma. During the first 6$\mu$ sec, glow discharge dued to DC pulse was investigated. Time varing phenomena of after-glow was also investigated during the last 5 $\mu$set. From results, it was found that the driving efficiency of a DC Plasma Display Panel could be improved when the diffusion of ions and electrons are controlled by the pulses applied to the auxiliary anode.

In this paper, several energy recovery circuits (ERC) for the plasma display panel (PDP) are reviewed and classified in a manner of operation characteristics. A typical ERC using the Regenerative Transformer (RT) is introduced and compared with conventional ones. RT-ERC can achieve zero-voltage-switching (ZVS) for main full-bridge switches and zero-current-switching (ZCS) for the resonant switches and diodes. The charging/discharging energy of panel capacitance is efficiently recovered with the RT and without a sub-circuit. The presented circuit is verified with simulation and experimental results.

The glass compositions of $PbO-SiO_2-B_2O_3$ system and $P_2O_5-PbO-ZnO$ system for the transparent dielectric materials for front panel and $P_2O_5-ZnO-BaO$ and $SiO_2-ZnO-B_2O_3$ for the reflective dielectric materials for back panel of PDP(Plasma Display Panel) were investigated. As a transparent dielectric materials for front panel, $PbO-SiO_2-B_2O_3$ glass showed good dielectric properties, high transparency and proper thermal expansion matching to soda-lime glass substrate. And the reflective dielectric materials for back panel were prepared from parent glass of $SiO_2-ZnO-B_2O_3$ system and oxide filler. It was found that these glass-ceramics are useful materials for reflective dielectric layers, as those have a similar thermal expansion to soda-lime glass plate, high reflectance, low sintering temperature.

21세기에 접어들면서 Digital시험방송의 시작과 다양한 Contents의 유입으로 평판디스플레이 (Flat Panel Display)에 관한 관심과 수요가 증가하고 있다. 이 중 PDP는 90년대 후반부터 양산 및 개발을 시작하여 현재는 40 inch에서 60 inch 화면 크기의 제품을 시장에서 구입할 수 있으며, 03년도에는 80 inch 크기의 Proto-type Model을 공개한 바 있다. PDP는 40 inch 이상의 대면적 구현이 용이하다는 점, CRT와 동등 수준의 화상 구현이 가능하다는 점, 제조공법이 간단하고 제조원가가 저렴하다는 점 등을 특징으로 시장을 확대하고 있으나, 좀 더 대중적인 디스플레이가 되기 위해서는 고휘도 및 고효율화, 화질개선 그리고 저가격화 등과 같은 과제를 해결하여야 한다. 본 논문에서는 PDP의 개발역사 및 시장현황, 구조 및 구동 방법 그리고 해결과제 및 전망에 대해서 포괄적으로 살펴보기로 한다.

We analyzed the effect of cell resolution on the luminous efficacy through three-dimensional numerical simulation to understand the inherent discharge mechanism change in the plasma display panel. As the resolution increases from VGA to Full HD, the luminous efficacy decreases. With higher Xe content, VUV generation efficacy of Full HD becomes much lower than those of VGA or XGA cells, due to the increased plasma loss and lower electron heating. However a long electrode gap $140{\mu}m$ in Full HD cell with Ne-Xe [20%] results in the high luminous efficacy comparable to that of the XGA cell with $60{\mu}m$ gap. When comparing the effects of Xe content variation on the luminous efficacy of two different subpixel types, i. e., SDE (Segmented electrode in Delta color arrayed, Enclosed subpixel) [1] and conventional stripe barrier type in the XGA and Full HD cells, the luminous efficacy of SDE structure shows higher improvement in Full HD resolution compared with that of conventional type XGA cell, whose cause is identified as the reduced plasma loss.
