Each of the plurality of pixels PX is connected to a corresponding scan line along the plurality of scan lines S1 to Sn, a corresponding data line among the plurality of data lines D1 to Dm, and a common control line. The plurality of scan lines S1 to Sn, the plurality of data lines D1 to Dm, and the common control line are connected to the display portion 10. In addition, although it is not directly illustrated in the display portion 10 of FIG. 1, each of the plurality of pixels PX is connected with a power supply line that is connected to the display portion 10, and thus receives first power ELVDD, second power ELVSS, and initialization power VINT.

Each of the plurality of pixels PX emits light of a predetermined luminance by a driving current supplied to an organic light emitting diode of the pixel according to a data signal transmitted through the corresponding data line among the plurality of data lines D1 to Dm.

The scan driver 20 generates and transmits a scan signal corresponding to each pixel through each of the plurality of scan lines S1 to Sn. That is, the scan driver 20 transmits a scan signal through a corresponding scan line to each of a plurality of pixels included in each pixel row.

The scan driver 20 receives a scan driving control signal SCS from the controller 50 and generates a plurality of scan signals, and sequentially supplies the scan signals to the plurality of scan lines S1 to Sn that are connected to the respective pixel rows. In addition, the scan driver 20 generates a common control signal, and supplies a common control signal to the common control line connected to the plurality of pixels PX.
