Enhanced Light Outcoupling on Photo-luminescent Devices with Microcavity

Abstract

Recently, microcavity is studied to reduce the optical loss of BLU and OLED. In this paper, we suggest applying microcavity to photo-luminescent lamp with plasma discharge technology to meet the display applications for a BLU for LCD. The structure of photo-luminescent lamp consists of SUS foil and ITO glass with microcavity. The opto-electric characteristics of photo-luminescent lamp with microcavity was evaluated. The brightness of photo-luminescent device was increased over 111 cd/m 2 with the adaptation of patterned microcavity at 30 μm. The 3D optical simulation verified the enhanced light outcoupling when microcavity applied to the device.

Usability Assessment of EMP for Improved Optical Properties of OMO Structure

“…ITO는 n-type의 금속 산화물 반도체로 가시광 파장대의 Photon Energy보다 더 큰 약 3.5 eV -4.3 eV의 Energy Bandgap을 가지기 때문에 가시광선 영역에서의 흡수가 이뤄지지 않고 해당 영역에서 높은 투과성을 가 진다 4) . 다만, ITO의 재료인 인듐의 경우 제한된 매장량으로 인하여 가격이 경제적이지 못하고 제작 과정 중 고 온의 열처리 과정을 거치기 때문에 ITO의 단일 구조만으로는 유연한 투명 전극 소자에 사용하기가 제한되는 상 황이다.…”

Development of pulse diagnostic devices in Korea

“…Early pulse diagnostic device models did not include the concept of minutely controlled applications of pressure, 59 but as the importance of the exerted pressure became highly emphasized, pressure control systems with air-pressure control 60 , 61 or a robotic arm 62 were developed. These systems have been used in basic measurement studies according to the exerted pressure, 63 , 64 hemodynamic studies, 65 , 66 pressure control method studies, 67 , 68 , 69 and research into pressure training systems. 70 Patents relating to the skin contact, fixation, and pressure control system are continuously being filed.…”
