Highly stable bottom gate thin film transistors(TFTs) with a zinc indium tin oxide(Zn-In-Sn-O:ZITO) channel layer have been fabricated by rf-magnetron co-sputtering using a indium tin oxide(ITO:90/10), a tin oxide and a zinc oxide targets. The ZITO TFT (W/L=$40{\mu}m/20{\mu}m$) has a mobility of 24.6 $cm^2$/V.s, a subthreshold swing of 0.12V/dec., a turn-on voltage of -0.4V and an on/off ratio of >$10^9$. When gate field of $1.8{\times}10^5$ V/cm was applied with source-drain current of $3{\mu}A$ at $60^{\circ}C$, the threshold voltage shift was ~0.18 V after 135 hours. We fabricated AM-OLED driven by highly stable bottom gate Zn-In-Sn-O TFT array.

This study has tried to grasp the awareness of employees in current apparel industry and common consumers about the show window in apparel shops. Interestingly, the employees were more concerned about the necessity of display and lighting than the consumers. However, the current display and lighting systems did not satisfy the consumers' requirements. Although they did not recognize that lighting display was closely related with display, color, and so on, they thought lighting indispensable. In consequnce, they light source and lighting method have to be carefully chosen, and the relationship between color and lighting should be fully considered as well.

Lighting in a fashion shop has an effect on customers, highlights the products on the shelf, and has become more important. Even though lighting has a significant effect on customers, the studies on fashion shop lighting have primarily focused on how to create lighting which can influence customers' purchase behavior, and their awareness and expectation. On the contrary, it's been hard to find a study on a quantified fashion shop lighting plan considering customer confidence. In a current fashion shop lighting plan, display lighting is planned indiscreetly. Therefore, this study conducted an investigation of the light environment of the current fashion shop and museum exhibits lighting. Through such processes, the possibility of applying fashion store display lighting environments was investigated. Finally, for the assessment of museum exhibitions lighting applying fashion store display lighting environments, a subjective evaluation method using light simulation was proposed.

LED lighting is used as artificial lighting for plant growth because it has high light efficiency and can radiate light of various wavelengths. In this paper, we have developed new structure LED lighting module to improve the performance of LED lighting for plant growth and proposed a lighting control system that can be controlled wirelessly. The proposed LED lighting module was fabricated using optical lens applied to tunnel light and simulated using Relux program. Results of simulation, we confirmed that the light distribution and average illuminance of the proposed lighting were improved. LED lighting control system was developed to wirelessly control R, G, B, W LED lighting according to plant type and growing season. Therefore, it is expected to provide the optimal lighting environment for plant growth and contribute to the improvement of farm productivity and convenience.

Organic light-emitting diodes (OLEDs) have already been commercialized for the mobile-phone display, TV, and lighting panels. Even though the OLED display for the mobile phones is now considered as the main stream display for the application, the OLED TV and lighting panels are having difficulty in their market due to their high prices despite the better performance to the competitors. In recent years, roll-to-roll production of the OLED has begun to be examined, and this method is opening a way to solve the high price problem. In this article, we introduce several important processes for roll-to-roll production of OLED and explain the development status to date.

본 연구는 최근 친수공간 확대로 수중보의 경관조명 수요가 급격히 늘어나고 있으나 현재 사용하는 수중보 조명등의 안전성과 연출효과가 떨어지는 등 문제점이 발생되므로 수중보 조명등을 개선하기 위해 안전성, 에너지 절감, 연출에 대한 유연성에 주관점을 두고 실태조사를 통한 문제점을 도출 분석하여 수중보조명등을 LED몰드 수중등으로 개발하였다. 본 연구의 결과물을 실용화함으로써 수중보 조명은 댐, 분수, 수영장 등 수변공간에 다양하게 확대 적용 가능할 것으로 사료된다.

We have fabricated transparent white organic light emitting diodes (WOLEDs) for lighting application. The structure property relationship of hybrid WOLEDs has been investigated and optimized devices showed high efficiency. Introduction of transparent cathode of LiF/Al/Ag into the hybrid WOLED led highly efficient WOLED with good transparency.

현대의 박물관에서는 조명에 의한 다양한 연출 효과를 얻기 위해 같은 전시공간 내에서도 여러 종류의 광원들을 사용한다. 이는 역으로 각각의 유물들이 다양한 환경의 빛에 노출되어 전시되고 있다는 것을 말해준다. 유물의 전시를 위한 최적의 조명환경 조건과 보존을 위한 최적의 조명환경 조건이 서로 다른 측면이 있다. 본 연구에서는 국립중앙박물관의 전시실 및 진열장에 조사되는 가시광선, 자외선 및 적외선 등을 측정하였으며, 측정 데이터를 바탕으로 국립중앙박물관의 조명환경을 비교, 분석하였다.
