    Abstract: A pixel for a display panel includes an organic light emitting diode and two driving transistors. The first driving transistor supplies current from a first power source to the organic light emitting diode based on a voltage applied to a first node. The second driving transistor coupled between an electrode of the first driving transistor and the organic light emitting diode. The second driving transistor is turned on or turned off corresponding to a data signal supplied from a data line. A third transistor, coupled between a gate electrode of the second driving transistor and the data line, is turned on when a scan signal is supplied to a scan line. A compensation circuit is coupled to the first node to compensate for a voltage corresponding to a threshold voltage of the first driving transistor.
