Abstract
A pixel according to an embodiment includes: an organic light emitting diode (OLED); a first transistor coupled between a data line and a first node and configured to be turned on when a scan signal is supplied to a scan line; a third transistor coupled between a reference power source and a second node and configured to be concurrently turned on and off with the first transistor; a storage capacitor coupled between the first node and the second node; a second transistor coupled between a first power source and the OLED and having a gate electrode coupled to the first node; a fourth transistor coupled between the first power source and the second node and having a gate electrode coupled to a control line; and a fifth transistor coupled between the second transistor and the OLED and having a gate electrode coupled to an emission control line.
