    Abstract: A pixel includes an organic light-emitting diode (OLED), a storage capacitor, and first to fourth transistors. The first transistor includes a gate electrode (GE), a first electrode (FE), and a second electrode (SE), and is configured to control, in response to a voltage of a first node (FN) coupled to the GE, current supplied from a first power source (PS) coupled to the FE to a second PS via the OLED. The storage capacitor is coupled between the FN and the first PS. The second transistor is coupled between a data line and the first transistor. The third transistor includes a FE coupled to the FN and a SE coupled to the SE of the first transistor. The fourth transistor includes a FE coupled to the FN and a SE coupled to the SE of the first transistor, and is configured to transmit an initialization voltage to the FN.
