Abstract

Organic electroluminesencent device have been studied because of its easy fabrication and high brightness for plate panel display instead of CRT and LED. There are some device structure for full color filter system can be applicable to the full color application if the blue light organic electroluminesencent device(OELD) is developed. In this study, We have investigated electro-luminescent (EL) characteristics of organic EL device using Alq3, PBD as emitting material. Current and luminance can be seen that express a similar relativity in voltage and could know that luminance is expressing current relativity.

유기 EL소자는 제작이 쉽고 휘도가 높아 CRT와 LED 대신 평판 디스플레이 패널의 광원으로써 많이 연구되어 지고 있으며, OLED 소자중 청색 OLED는 풀컬러 적용 어플리케이션에 적용할 수 있기 때문에 이에 대한 연구가 이루어 지고 있다. 본 연구에서는, 발광 소재로 PBD, Alq3를 사용하여 유기 EL 디바이스의 전기 발광 특성을 측정하였으며, 전류와 휘도는 전압과의 관계에서 알 수 있었고 휘도와 전류의 관계를 제시하였다.
