Abstract:
유기 발광소자 또는 유기 트랜지스터와 같은 유기 전자 소자를 기판 상에 제조한 후, 유기/무기 복합층 또는 무기층을 라미네이트화하고 상기 라미네이트에 접착시트를 부착한 다음 이를 기판 상에 접착 테이핑(tapping) 함으로써 유기 전자소자를 밀봉하는 하우징 구조를 만들고, 그 내부에 수분 및 산소에 대한 차단성이 탁월한 액상오일을 베리어로서 채워 넣은 구조의 엔캡슐레이션 및 그 방법이 개시되어 있다. 본 발명에 따른 엔캡슐레이션 방법은 접착시트가 부착된 라미네이트로 기판에 간단히 테이핑하는 방법을 사용하므로써, 고가의 증착 장비를 사용하지 않아 저렴한 생산비용으로 엔캡슐레이션이 가능하며, 간단한 공정을 통해 짧은 시간에 원하는 형태의 엔캡슐레이션 구조를 형성할 수 있을 뿐 아니라, 액상의 오일을 베리어로서 사용하여 소자열화의 원인이 되는 수분과 산소의 침투를 효과적으로 차단할 수 있다. 또한, 본 발명에 따른 엔캡슐레이션 방법은 가벼운 유기/무기 복합층 또는 무기층을 하우징으로 사용하므로써, 큰 면적을 갖는 유기 발광소자를 제작하는데 적합하며 또한 구부림이 가능한 장점이 있다.
