A plasma display panel(PDP) with a new discharge cells are investigated electrically and optically. These cells have the structure of a long discharge path length and a small electrode area. They have shown a higher luminous efficiency and a lower power consumption about $30{\sim}40%$ improvement than the conventional standard ac PDP cells.

The understanding of reset scheme is essential for the driving of AC PDP (Plasma Display Panel). The characteristics of reset period of AC PDP was examined with the variation of pulse time and voltage in the ADS (Address Display Separated) driving method presented by Fujitsu,. The addressing characteristics showed drastic change as a function of the erasing time and addressing pulse width. In this paper, these results were explained by the change of wall charge variation, and it was estimated with the currents through each electrode.

The effects of an auxiliary address pulse driving scheme, in which an auxiliary short pulse is applied to the address electrode during a sustain-period, were examined under the various image patterns of the 42-inch WVGA ac-PDP. When the auxiliary address pulse driving scheme was applied, the luminance of the red, green and blue cells were measured respectively. And the luminance, luminous efficiency, and current were measured under the full-white pattern of the 42-inch ac-PDP. As a result, the luminance of blue cells was improved approximately by 17 %, whereas the luminous efficiency of the full-white pattern was improved approximately by 34 % without a misfiring discharge in comparison with conventional driving scheme.

The surface discharge type ac plasma display panel(ac PDP) is a flat display devices using gas discharge. In ac PDP, parallel electrodes covered with dielectric layer are on a substrates. The discharge current characteristics are affected by cell structure. In this study, the relationship between the principal design factor and discharge characteristics is discussed, based on experiment, and the current waveform is measured by voltage detector and storage O.S.C. as a parameter of design factor, e.g., electrode gap and width.

The thin film that is electrically conductive and optically transparent is called conductive transparent thin film. ITO(Indium-Tin Oxide) which is a kind of conductive transparent thin film has been widely used in solar cell, transparent electrical heater, selective optical filter, FDP(Flat Display Panel) such as LCD(Liquid Crystal Display), PDP(Plasma Display Panel) and so on. Especially in PDP, ITO films is used as a transparent electrode in order to maintain discharge and decrease consumption power through the improvement of cell structure. In this study, we prepared ITO by reactive r.f. sputtering with indium-tin(Sn 10wt%) alloy target instead of indium-tin oxide target. The ITO films deposited at low temperature 15$0^{\circ}C$ and 8% $O_2$. Partial pressure showed about 3.6 Ω/$\square$. At the end of firing, the resistance of ITO was decreased, the optical transparence was improved above 90%.

본 연구에서는 우리는 ITO전각을 사용하지 않는 새로운 전극 구조를 가지는 AC-PDP를 제안하였다. 제안한 구조는 댄스 전극과 유전체를 교대로 쌓아 올린 구조로서 긴 방전 경로와 낮은 방전 전류, 높은 휘도의 특징과 높은 효율을 내었다. 먼저 2-D 시뮬레이션의 결과를 기초로 하여, 제안한 구조를 가지는 테스트 패널을 제작하였다. 기존의 전극구조와 비교하였을 때, 제안한 구조는 발광 효율이 약 3배 증가하였고, 휘도는 약 50% 증가하였으며 방전전류는 약 60% 감소하였다.

In this study, we examine the effects of auxiliary pulse on the image sticking in ac PDP. A relatively low voltage square pulse applied to the address electrode before and after erasing period is found to be quite effective in reducing the line image sticking in the boundary between off and on block of full white pattern.

본 연구에서는 기존의 ITO전극을 사용하지 않는 새로운 전극구조를 가지는 AC-PDP를 제안하였다. 제안한 구조는 상판의 유지전극들을 패터닝된 유전체층 사이에 Ag 전극을 경사형 으로 형성하여 만든 구조이다. 테스트 패널은 각각 $250{\mu}\;300{\mu}m,\;350{\mu}m$의 유지전극 간격들을 가지는 제안된 구조와 기존의 유지전극 간격 $60{\mu}m$의 ITO 구조를 reference로하여 제작하였다. 제안한 구조의 휘도는 방전 갭의 길이에 비례하여 증가하였고 방전전류가 약 $33{\sim}70%$ 감소하여 효율이 유지전극 간격 $300{\mu}m$에서 최대 130% 증가하여 2배이상 증가하였다.

기존의 fence전극구조는 ITO구조에 비해 휘도가 감소하여 효율이 떨어지는 것으로 알려져 있다. 따라서 효율 상승을 위하여 다음과 같은 fence 구조를 제안하였다. 실험은 reference(II-fence형 전극구조)와 제안된 구조(II-fence형 돌기격벽측배치)로 구성되어있는 4-inch AC-PDP 패널을 직접 제작하여 discharge current, luminance, luminous efficiency를 측정하여 비교하였다. 제안된 구조의 휘도는 약 5% 감소하였으나, 방전전류가 최대 14% 감소하였고, 효율면에서 최대 12%의 효율 상승을 가진다.

PDP는 LCD, OLED등과 같은 FPD(Flat Panel Display)들과는 차별화된 우수성을 가지고 있다. 따라서 본 논문에서는 AC-PDP에서의 MgO박막의 material property를 향상시키기 위하여 MgO pellet에 미소량의 Ca를 첨가하였으며 이에 따른 MgO박막을 통해 Ca의 첨가에 따른 효과를 분석하였다. MgO박막은 e-beam evaporation 방법을 사용하였으며 4인치 테스트 패널을 만들어서 방전개시전압, 방전유지전압, 어드레싱지터를 측정하였으며 방전효율은 Ca가 0.025%, 0.035%, 0.042%가 첨가 되었을 때 각각 비교하였으며, 0.035%가 첨가 되었을 때가 가장 좋은 효율을 가진다.
