摘要： A scan driver for a display device includes a plurality of stages outputting scan signals. A first stage of the plurality of stages includes first to sixth transistors connected to a first carry clock line, a carry line, a previous carry line, and a second carry clock line. In a first frame period, the second carry clock line is configured to receive a second carry clock signal having at least one pulse with substantially the same phase as at least one of first pulses of a first carry clock signal to be applied to the first carry clock line.

摘要： A pixel includes first through fourth transistors and storage capacitor. The first transistor controls an amount of current flowing from a first driving power source to a second driving power source, via an organic light-emitting diode, based on a voltage of a first node. The second transistor is coupled between a first electrode of the first transistor and the first node, and is turned on when a scan signal is supplied to a scan line. The third transistor is coupled between a second electrode of the first transistor and a reference power source, and is turned on when the scan signal is supplied. The fourth transistor is coupled between an anode electrode of the organic light-emitting diode and a data line, and is turned on when the scan signal is supplied. The storage capacitor is coupled between the first node and the anode electrode of the organic light-emitting diode.
