Zusammenfassung:	The present invention relates to a pixel circuit, electroluminescence display using the same, and method for sensing characteristics of light emission control transistor using the same. The present invention includes: a first light emission control transistor controlled according to a light emission control signal to supply a high potential power supply voltage to a driving transistor; and a second light emission control transistor controlled according to a scan signal to supply the high potential power voltage to the driving transistor, and thus even when PWM is driven, the characteristics of the driving transistor can be sensed in real time. 본 발명은 픽셀 회로, 이를 이용한 전계 발광 표시장치, 및 이를 이용한 발광 제어 트랜지스터의 특성 센성 방법에 관한 것으로, 발광 제어 신호에 따라 제어되어 고전위 전원 전압을 구동 트랜지스터에 공급하는 제1 발광 제어 트랜지스터와, 스캔 신호에 따라 제어되어 상기 고전위 전원 전압을 구동 트랜지스터에 공급하는 제2 발광 제어 트랜지스터를 구비하여, PWM 구동시에도 구동 트랜지슽터의 특성을 실시간으로 센싱할 수 있도록 한 것이다.
