OLED 조명은 얇고 가볍고 열이 나지 않은 이점을 가질 뿐만 아니라 형광등 절반의 전력으로 같은 밝기가 구현 가능하여 저전력 조명기구가 가능하게 될 것이다. 또한 태양광에 가까운 균일한 면광원으로 부드러우면서 자연스러우면서 다양한 모양의 등 기구 제작이 가능한 차세대 조명이다. 본고에서는 OLED 조명의 발광원리와 특징, OLED의 고성능화를 위한 고효율 재료기술, 광추출 기술, 백색 OLED 기술, 봉지기술 등에 관하여 기술하였다. 또한 OLED 광원 산업체의 동향을 한국을 중심으로 일본업체, 대만/중국업체, 미국업체, 유럽업체 순으로 살펴보았다. OLED 조명은 2020년에 이론적인 발광 효율인 200lm/W가 구현이 되면 일상생활의 조명이 획기적으로 변화되는 사회를 맞을 것으로 기대되므로, 전 세계적으로 시장형성 초기단계이므로 선제적이고 전주기적인 지원을 통하여 시장선점 및 확대가 필요하다.
