| Zusammenfassung: | The present invention provides a pixel driving circuit of a n^th line, which is effective for suppressing a leakage current. The pixel driving circuit comprises: an organic light emitting diode (OLED); a driving transistor driving the OLED; and a first transistor connected between a first node to which a gate electrode of the driving transistor is connected and a second node to which an initialization voltage is supplied at a different potential value according to timing, and controlled by a scan signal of an (n-1)^th line.
본 명세서는 제n 라인의 화소 구동 회로를 개시한다. 상기 화소 구동 회로는. 유기발광 다이오드(OLED); 상기 유기발광 다이오드(OLED)를 구동하는 구동 트랜지스터; 상기 구동 트랜지스터의 게이트 전극이 연결된 제1 노드 및 초기화 전압이 타이밍에 따라 다른 전위 값으로 공급되는 제2 노드 사이에 연결되고, 제n-1 라인의 스캔 신호에 의해 제어되는 제1 트랜지스터를 포함한다. |
