Abstract

In an organic light emitting display (100) including a pixel, and a method of driving the same, the pixel (150) includes an organic light emitting diode (OLED), a storage capacitor (C st ) coupled between a first power supply (ELVDD) and a first node (ND1), a first transistor (M1) for controlling a current that flows from the first power supply (ELVDD) to a second power supply (ELVSS) through the OLED in response to a voltage applied to the first node (ND1), a second transistor (M2) coupled between a data line (D m ) and a first electrode of the first transistor (M1) and turned on when a control signal is supplied through a control line (CL n ), a third transistor (M3-1, M3-2) coupled between the first node (ND1) and a second electrode of the first transistor (M1) and turned on when a scan signal is supplied through an nth (n is a natural number) scan line (S n ), and a fourth transistor (M4-1, M4-2) coupled between an initializing power supply (V int ) and the first node (ND1) and turned on when the scan signal is supplied through an (n-1)th scan line (S n-1 ).
