High Xe-content PDP characteristics are discussed. A high efficacy, up to 5 lm/W for a 50% Xe in Ne gas mixture, is realized in 4-inch color PDP test panel designs with low cost stripe-type barrier rib structures, that are powder blasted in soda lime glass. Furthermore, for a high Xe-content a high luminance can be obtained with a relatively small electrode area. Therefore the inter cell gap and the driving margin can be increased in a stripe-type barrier rib structure. Finally, for a high Xe-content the panel lifetime increases, due to increasing luminance and firing voltage stability. Clearly, these findings may direct the design development for next generation PDPs towards a high Xe-content

The discharge characteristics of He-Ne-Xe gas mixture with the variation of Xe content are investigated through the numerical simulation. VUV efficacy in the gas condition of low Xe content increases due to more excitation and the case of high Xe content shows the improvement of VUV efficacy with the increase of He content but decreased VUV efficacy after tthe He mixing ratio of He and Ne is 0.5 due to frequent ionization.

Plasma display panel(PDP) 의 동작전압, 밝기, 방전늦음 시간, 광 효율, 수명, 잔상 등의 방전특성은 PDP내부의 동작가스의 혼합비율에 영향을 많이 받기 때문에, 높은 비율의 Xe 가스가 첨가된 PDP의 연구가 최근에 활발히 진행되고 있다. 그러나 high Xe이 패널에 주입되더라도 방전 개시전압과 유지전압의 상승 등의 문제점 들이 발생하고 있다. 본 연구에서는 이러한 문제를 해결하기 위한 방법으로 Ne+Xe+Kr 3원 가스에서의 가스혼합비율에 따른 방전 전압과 마진, 휘도, 광 효율을 연구하였다.

The use of high Xe content gas is a powerful method for improving the discharge efficacy in PDP, but the accompanying high driving voltage prevents it from being used aggressively. In this paper, we tried to find a method to lower the driving voltage under high Xe gas condition with a new protecting layer. The effective secondary electron emission caused by Xe ions can result in the low voltage driving in panels with high Xe content gas and more importantly high luminous efficacy which were confirmed with the computer simulation and panel experiment.

최근 3전극 면방전형 AC-PDP 효율 향상을 위해 높은 Xe 함량비의 방전기체에 대한 연구가 수행되고 있으나, Xe 함량의 증가로 인한 방전전압의 상승 문제는 여전히 해결되지 못한 실정이다. 본 연구에서는 높은 Xe 함량을 가지는 저압의 방전기체를 사용하여 기존 고압(400 Torr 이상)의 방전기체와 방전특성을 비교분석하고, 특히 진공자외선 발광특성을 분석하였다. 실험결과 Ne+Xe (30%) 200 Torr 방전기체와 Ne+Xe (15%) 400 Torr 방전기체의 방전 개시전압은 각각 354V 와 389V 로서, 방전 개시전압은 35V 정도 낮아졌으나, 140nm$\sim$200nm 영역의 진공자외선의 방출량은 유사한 경향을 보임으로써 결과적으로 Ne+Xe (30%) 200 Torr 방전기체의 진공자외선 발광효율이 약 30%, 증가됨을 확인할 수 있었다.

We investigated the effect of sustain electrode gap variation with high Xe content in an ac Plasma Display Panel through two-dimensional numerical simulation to understand the inherent high luminous efficiency mechanism. For the low Xe content, the optimal sustain electrode gap turned out to be about 200 ${\mu}m$, but with higher Xe content, the VUV generation efficiency increased as the electrode gap increases beyond 200 ${\mu}m$. We found that it is due to higher electron heating efficiency in the cathode sheath under the condition of long electrode gap and high Xe content.

본 논문에서는 방전유지전극사이에 유전체 공극이 존재하는 능선형상의 상판구조를 제안하였다. 이 구조는 상판의 방전 유지 전극사이 강한 전계를 이용하여 동작전압을 감소시킬 수 있고 이로 인한 Xe의 주입비율을 증가시켜 휘도 및 발광효율을 향상시킬 수 있는 구조이다. 실험에서는 6인치 테스트 패널을 사용하였으며 기체 압력을 450 torr로 유지하면서 Xe 함량을 10 %, 15 %, 20 %, 30 %, 50 %로 변화하여 실험하였다. 실험결과, 10 %의 동일한 Xe 기체를 주입한 결과, 제안된 구조를 적용할 경우, 방전개시전압과 방전유지전압이 각각 79 V, 74 V 감소하였으며 10 %의 Xe을 주입한 일반적인 구조와 50 %의 Xe을 주입한 제안된 구조의 휘도와 발광효율 비교에서 본 논문에서 제안한 구조가 비슷한 구동전압 범위에서 일반적인 구조에 비하여 효율은 50.9 % 향상되었고, 휘도는 33 % 향상됨을 알 수 있었다.

The improvement of luminance and luminous efficiency is the one of the most important part in AC-PDPs. To achieve high luminance and luminous efficiency, high VUV emission efficiency is needed. We measured the emission spectra of vacuum ultraviolet(VUV) rays in surface discharge AC-PDP with binary and ternary gas mixtures of Ne-Xe and He-Ne-Xe. The influence of He-Ne-Xe gas-mixture ratio on excited $Xe^{\ast}$ resonant atoms and $Xe_2$$^{\ast}$ dimers has been investigated. It is found that luminous efficiency of ternary gas mixture, He-Ne-Xe, is shown to be much higher than that of binary gas mixture of Ne-Xe.

Recently color AC PDP(plasma display panel) technology is rapidly improved. However, the luminous efficiency improvement is a key issue for making plasma display into a large-area flat display. In this paper, we suggest a new concentration of Xe in He-Ne-Xe gas mixture in order to achieve a high luminous efficiency of color AC PDPs. We calculated the densities of 25 species as a function of the time zero dimensional simulation using CVODE solver and we compared the results of zero dimensional simulation with a measurement of photo wave brightness and luminous efficiency, in order to find the optimum mixing condition of He-Ne-Xe gas in color plasma display panel. We obtained a high discharge speed under Xe mixing ratio of 1% by simulation and confirmed that through measuring photo wave.

Various approaches were undertaken by major PDP makers in order to improve the luminous efficacy of the plasma discharge cells. There have been many reports that state that using a high Xe content PDP is one of the most promising key technologies available to improve the luminous efficacy. In the case of the higher Xe content panel, the higher address and sustain voltage were needed to drive the panel under the same reset condition. In this study, a variety of Xe content panels were investigated in order to examine wall voltage transfer behaviors. The transferred wall voltage status after addressing discharge at the same driving condition was analyzed by comparing Vt close curve of high and low Xe content panels. Through this analysis of Vt close curve difference, the driving waveform of a high Xe panel was quantitatively adjusted Under the same address voltage condition, results showed that the amount of the transferred wall voltage and Vt close curve after addressing discharge was matched for the first sustain discharge. Taking these results into consideration, we conclude that the driving waveform for different Xe content panels could be designed for the desired addressing discharge condition and the wall voltage state of the cell could be quantitatively controlled and measured through these approaches.
