1. A pixel comprising:

  • an organic light emitting diode (OLED);

    a first transistor configured to control current from a first power source to the OLED according to a data signal;

    a second transistor configured to selectively connect the data signal to the first transistor according to a first scan signal on an nth (where n is a natural number) scan line;

    a capacitor connected to the gate terminal of the first transistor configured to store a voltage corresponding to the data signal; and

    a third transistor having a conductivity type different from the conductivity types of at least one of the first and second transistors, the third transistor being diode connected to an (n−

    1)th scan line and configured to be turned on when a second scan signal is supplied to the (n−

    1)th scan line.
