  • We investigated the effect of relative dielectric constant of front dielectric layer on the efficacy of plasma display panel. Dielectric materials with relative dielectric constant of around 6 and 7 were developed. When the front dielectric layer had a low relative dielectric constant, power consumption decreased more than luminance did. And it led to efficacy enhancement. However, the minimum sustain voltage increased.

  • We fabricated the 3.5 inch QCIF AMOLED panel with ultra low temperature polycrystalline silicon TFT on the plastic substrate. To reduce the leakage current, we used the triple layered gate metal structure. To reduce the stress from inorganic dielectric layer, we applied the organic interlayer dielectric and the photoactive insulating layer. By using the interlayer dielectric as a capacitor, the mask steps are reduced up to five.

  • In this study, a high luminous efficacy AC-PDP panel with long discharge gap and grooved dielectric layer has been studied. By applying this high efficacy concept and optimized driving waveform featuring negative biased sustain, ${\sim}2.6lm/W$ of luminous efficacy was achieved in 42- inch HD panel. Modified fabricating process and new discharge cell structure were investigated to obtain improved uniformity and operating characteristics.

  • 광가입자망의 궁극적인 목표라 할 수 있는 FTTH 서비스가 일부 지역에서 시범사업이 진행되고 있고, 금년 8월부터는 KT가 PON을 이 용한 FTTH 서비스를 제공할 예정이다. FTTH 서 비스를 위해서는 전송장치 및 서비스 개발과 동시에 전화국사에서 가입자까지 이르는 전송매개체인 광선로시설에 대한 효율적이고, 경제적인 구축 기술을 필요로 하게 된다. 본 논문에서는 FTTH구축을 위해 소요되는 선로시설을 대상으로 기술적 특징을 조사 분석하고, 주요 시설별 기능요구사항 및 선로시설 구축에 요구되는 특성 등을 분석하였다.

  • This paper is a study on remote monitoring by measuring harmful gases using LabVIEW and MyRIO. Most gas measurements using Arduino are somewhat limited in using multiple sensors. MyRIO can measure multiple sensors, so it suggests a method of wirelessly transmitting them and monitoring them through LabVIEW.
