Abstract

A pixel (10) for an organic emitting display includes a first transistor (P1) coupled between a first power source (ELVDD) and a first node (N1), the first transistor (P1) including a gate electrode coupled to a second node (N2), an organic light emitting diode (OLED) coupled between the first node (N1) and a second power source (ELVSS), a second transistor (P2) for supplying a data signal to the second node (N2) in response to a scan signal, a third transistor (P3) having a source electrode (106a) and a drain electrode (106b) electrically coupled to each other, the third transistor (P3) being coupled between the first power source (ELVDD) and the second node (N2), and a fourth transistor (P4) having a source electrode and a drain electrode electrically coupled to each other, the fourth transistor (P4) being coupled between the second node (N2) and the first node (N1).
