| 유기물 반도체 물질의 특징은? | 그러나 전도성 유기물 반도체 물질과 이의 손쉬운 합성법이 개발되면서 유기물 반도체 물질은 세계산업에서 중요한 요소가 되었다. 더 나아가, 유기물 반도체 물질은 가볍고 유연하여 다양한 분야 적용 가능성이 뛰어나기 때문에 유기물 반도체에 대한 연구가 최근 30년 간 급격한 속도로 증가하고 있다.1-4) 이러한 광범위하고 지속적인 연구의 결과로 유기물 반도체를 이용한 소자의 성능이 향상되었다. | |
| 유기 반도체의 적용분야는? | 1-4) 이러한 광범위하고 지속적인 연구의 결과로 유기물 반도체를 이용한 소자의 성능이 향상되었다. 유기 반도체는 박막 트랜지스터, 태양 전지 및 발광 장치와 같은 다양한 전자 장치에 연구 되고 적용되고 있다. 유기 발광 다이오드(organic lightemitting diode, OLED)에 적용되는 유기 재료의 경우에는 큰 엑시톤의 결합 에너지 때문에 빛을 방출하는데 한계가 있었으나 최근 새로운 유기 반도체가 개발됨에 따라 OLED의 효율, 밝기 및 안정성이 크게 향상되었다. | |
| OLED의 높은 선명도, 넓은 시야각, 낮은 동작 전압이 가져오는 이점은? | 반면에, OLED는 블랙 레벨 및 명암비가 우수하고, 높은 선명도, 넓은 시야각, 낮은 동작 전압, 빠른 응답 시간 및우수한 유연성을 갖는다.5-7) 이러한 이점 때문에, OLED 는 디스플레이에 점점 더 많이 적용되고 있을 뿐만 아니라 기술의 개발로 인해 가격도 상당히 하락했다. 그로인해 OLED는 첨단 제품에 점점 더 많이 응용되고 있으며 디스플레이 시장뿐 아니라 조명 시장에서도 시장 점유율이 점차 증가하고 있다. |
