Abstract: 능동형 유기전계발광장치의 화소 회로가 개시된다. 데이터 신호가 인가되고, 구동 트랜지스터의 문턱전압을 저장하는 구간에서 화소 회로는 구동 트랜지스터의 게이트 단자에 병렬로 연결된 2개의 커패시터를 구비한다. 즉, 스토리지 커패시터와 보조 커패시터가 화소 회로에 구비되고, 2개의 커패시터들에 구동 트랜지스터의 문턱전압이 저장된다. 발광구간에서 구동 트랜지스터의 문턱전압은 보상되고, 문턱전압의 영향은 배제된다. 또한 구동 트랜지스터의 게이트 단자에 병렬로 연결된 커패시터들에 의해 게이트 단자에서의 시정수는 증가한다. 따라서, 박막 트랜지스터에서 누설 전류가 발생하더라도 게이트 단자에서는 일정한 전압을 유지할 수 있다.
