  • A MgO layer is used as electrode protective film in the alternating current plasma display panel (AC PDP). The properties of MgO layer are thought to be one of the most important factors that affects the panel reliability through the firing voltage variation. In this study, we investigated the relations between the surface characteristics and e-beam evaporation process parameters such as deposition rate, temperature of substrate and distance between the MgO pellet and substrate. To produce the MgO layer of (200) crystal orientation, we suggest the high temperature of the substrate, the long distance between the pellet and substrate and the high deposition rate.

  • "CRT" which had dominated the market of display until 2000 is not appropriate for information indicating media due to several limitations. Thus, TFT-LCD, PDP, OLED, etc are growing in display industry instead of CRT because they meet demands of information indicating media. OLED display which responses within 1ms fits any picture manifestation medias because it uses self radiance OLED for picture clement that has no obstacles in showing the angle of vision. OLED's characteristic of action is very sensitive to thickness of electrode so that this has been an important issue. This study tried to find the most suitable thickness of electrode using ITO, Mo, and AL. Using the results of IVL measurements, analyzed equality of electrode board. As a result, found the thickness of electrode that has high electrical efficiency and optimized it.

  • 각 종 전자 디바이스의 투명전도막으로 많이 사용되는 ITO 및 ZnO:Al 박막을 스퍼터링법에 의해 제작하였다. 가스압력 및 기판온도 등의 최적조건하에서 제작된 ITO 및 ZnO:Al 박막은 각각 $1.67{\times}10^{-3}[{\Omega}-cm]$$2.2{\times}10^{-3}[{\Omega}-cm]$의 비저항율과 89.61[%] 및 90.88[%]의 가시광 영역에서의 광투과율을 나타내었다. ZnO:Al과 ITO 투명전극을 이용하여 5인치의 PDP 셀을 동일한 제조조건하에서 제작하였다. ZnO:Al의 경우 Ne(base)-Xe(8%)의 가스 혼합비, 그리고 400[Torr]의 압력조건에서 가장 잘 동작되었으며, $200{\sim}300$[V]의 인가전압 범위에서 $836[cd/m^2]$의 평균휘도를 나타내었다. 고휘도 및 저 소비전력특성을 위한 중요한 파라메타인 광효율은 전원 주파수가 $10{\sim}50[Khz]$의 범위에서 $1.2{\sim}1.6[lm/W]$정도를 나타내었으며, ITO의 경우 휘도 및 광 발생 효율은 약 10[%]정도 상승하였다.

  • We measure the spatiotemporal wall charge distributions on sustain and address electrodes during reset period in an ac PDP cell using the longitudinal electro-optic amplitude modulation method. We apply several reset waveforms like as ramp, exponentially growing and high voltage pulse, and compare the wall charge characteristics on address electrode as well as sustain electrodes for each reset waveforms.

  • High Luminance PDPs have been developed using high efficient electrode structure, discharge gas and fishbone type barrier ribs. New phosphors for the good picture quality were developed. Also, New manufacturing processes such as CPBB were applied in order to reduce processing steps. High Luminance of 1,000 $cd/m^2$ was obtained in the series of 42 inch, 50 inch and 60 inch PDPs.

  • Plasma Display Panels (PDPs) have illustrated impressive results in terms of light emission efficiency of the Ne-Xe mixture compared with the He-Xe mixture. However, He-Xe has shown to achieve superior color purity. This paper presents the optimization of excitation efficiency and color purity for He-Ne-Xe ternary gas mixtures. Furthermore, we investigate the effect that a protective dielectric layer has on UV photon efficiency in a matrix known as electrode type PDP.

  • The bus electrode is composed of two layers. One is the black matrix(BM) and silver layer is formed on top of black layer. The BM paste is made by mixing $Co_3O_4$ black powder with photosensitive vehicle and rheological additives. In this work we studied the effect of $Co_3O_4$ black powder and glass frit on the rheological property of photosensitive BM paste. We also examined how the size and content of black powder and glass frit affect the transmittance and reflectance of the BM layer after sintering.

  • We propose the method which is possible to fabricate the electrodes with the fine pattern and low resistance by photolithography and electroplating. The widths of pattern fabricated were 30, 50, 70 and 100um and the thickness could be up to $10{\mu}m$. The resistivity of the copper electrode electroplated was below $2.0{\mu}{\Omega}$ cm which is about half of photosensitive silver electrode. Dielectric layer was coated on the electrodes by screen printing and the pores harmful to the discharge were not formed after heat treatment. In the viewpoint of resistance and patterning, this method has much higher potential for large area display than other methods like screen printing, photosensitive conductive paste method and sputtering.

  • The discharge characteristics of the face-to-face sustain electrode structure employing auxiliary address pulse are investigated under a sustain driving frequency of 20 kHz and various auxiliary address pulse widths (500 ns, $1{\mu}s$, $2\;{\mu}s$) in the 6-in. test panel (42-in. Full HD grade) with a pressure of 450 Torr and a 4 % Xe-content. The luminance and the luminous efficiency at the auxiliary address pulse width of 500 ns are improved more than these of $1\;{\mu}s$ and $2\;{\mu}s$. At the auxiliary address pulse width of 500 ns, the luminous efficiency shows about 0.96 lm/W at the auxiliary pulse of 90 V and the sustain voltage of 260 V.

  • Laser direct patterning is one of new methods which are able to replace a conventional photolithography. In order reduce the fabrication cost and to improve the luminous efficiency of AC plasma display panels (PDPs), in this experiment, a Q-switched Nd:$YVO_4$ laser was used to fabricate T-shaped indium tin oxide (ITO) display electrodes. For the laser beam scanning speed from 100 mm/sec to 800 mm/sec, T-shaped ITO patterns were clearly obtained and investigated. The experimental results showed that the optimized T-shaped ITO electrode was obtained when the lasers scanning speed was 300 mm/s.
