Flat Panel Displays (FPDs) have made a revolution in the display industry. TFT-LCD (Thin Film Transistor Liquid Crystal Display) has been the main player of FPD for last two decades. As the industry continuously develops the technology for better performance with lower cost is constantly demanded where several post LCD technologies are being developed. One of the prime candidates of post LCD technology is AMOLED (Active Matrix Organic Light Emitting Diode) that is considered to be an ideal FPD due to its extraordinary display performance and potentially low cost display structure. This technology has been accepted to small size display applications, such as cellular phone, PDA and PMP, etc. In this paper it is discussed that how this technology can be extended to large size display applications, such as TV. The technical issues and solutions of TFT backplane and color patterning of OLED materials are discussed and proposed

In this Study, as the structure of smart phone display becomes thin to catch up with slim product trend, the reliability of display module is on the rise as a issue for product design. Especially, almost part of cellular phone should undergo drop test when they fall 1.5m above ground. Thus many manufacturers have considered design guide line using CAE and simulation for more efficive usage of limited resources om the martket. This test simulates the case when cellular phone slips through user's flingers while he is talking on the phone. This paper studies a drop simulation of glass for display in smart phone. This design for reliability improvements are suggested on the basis of the results of FE Analysis and display of smart phone design.

철은 사람에게 필수적인 영양소일 뿐 아니라 해로운 요소로도 작용한다. 이러한 철에 의해 진핵생물체에서 발현이 조절되는 유전자들을 밝히기 위해 철이 첨가되거나, 제거된 조건에서 배양된 HeLa세포로부터 RNA differential display 방법을 이용하여 발현 또는 억제되는 유전자들을 선별하였다. 모두 24개의 유전자가 선별되었으며, 염기배열 확인과 northern blot의 발현 확인과정을 거쳐 4개의 유전자들이 철에 의해 영향을 받는 것으로 확인되었다.

In the past, display devices have undergone many changes, such as plasma TVs and LCDs, and have continued to develop. Recently, new display technologies, such as Organic Light Emitting Diode displays and Inorganic Light Emitting Diode displays, have been developed. Among them, Micro LED displays have the potential to improve performance more than LCDs and OLEDs, but a lot of effort and time are needed until the mass production technology (transfer and bonding) of Micro LED displays is developed. We have developed a new Micro LED display light source that can be produced using existing transfer and bonding process technologies to enable faster commercialization of Micro LED in the industry. This light source is TFT deposition on LED. TFT deposition on LED has the advantage of being able to produce displays using existing process technology, making early commercialization of display application products possible. In this study, we applied the Active Driving method to verify the performance of TFT deposition on LED as a display to determine its commercialization potential. Additionally, to facilitate faster application of Micro LED in the industry, we applied TFT deposition on LED to Optical Wireless Communication systems, which are widely used in application service areas such as safety/security and sensors, to verify its communication performance. The experimental results confirmed that TFT deposition on LED is not only capable of AM driving but can also be applied to OWC systems.

디스플레이산업은 세계 최고의 수준을 달성한 한국의 대표적 주력 산업이다. LCD 패널의 대표기업들을 중심으로 한 기존의 연구와는 달리, 본 연구는 가치사슬 관점과 아키텍처 관점을 결합하여 후방가치사슬(upstream) 영역에 속한 소재부품 장비 공급기업에 중점을 둔 산업의 발달구조와 발전추이 특성을 분석하였다. 2002년부터 2015년까지 208개 기업에 대한 매출액 및 연구개발비 자료를 활용하여, 산업의 가치사슬별 성장 및 혁신 특성을 분석하였다. 결과, 소재부품기업과 장비기업은 패널 제조 공정별로 상반된 발전 추이가 있음을 규명하였다. 본 연구는 디스플레이산업과 같이 대규모 시스템 공정산업의 경우는 공정산업의 특성을 반영하여 기존의 가치사슬 관점에 아키텍처 혁신 관점을 반영한 분석 틀을 통하여 향후 산업 기술 전략과 정책의 방향을 제시하였다는 점에 의의가 있다.

In this paper, we propose a floral scent recognition using odor sensors and a odor display using odor distribution system. Proposed odor recognition has method of correlation coefficient between sensors that select optimal sensors in floral scent recognition system of selective multi-sensors. Proposed floral scent recognition system consists of four module such as floral scent acquisition module, optimal sensor decision module, entropy-based floral scent detection module, and floral scent recognition module. Odor distribution system consists of generation module of distribution information, control module of distribution, output module of distribution. We applied to floral scent recognition for performance evaluation of proposed sensors decision method. As a result, application of proposed method with floral scent recognition obtained recognition rate of 95.67% case of using 16 sensors while applied floral scent recognition system of proposed sensor decision method confirmed recognition rate of 96% using only 8 sensors. Also, we applied to odor display of proposed method and obtained 3.18 thorough MOS experimentation.
