Abstract: A display device includes pixels. Each of the pixels includes: a first transistor including a gate electrode connected to a first node, a first electrode connected to a second node, and a second electrode connected to a third node; a second transistor including a gate electrode connected to a first scan line, a first electrode connected to a data line, and a second electrode connected to the second node; a first sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the first node, and a second electrode connected to a fourth node; and a second sub-transistor including a gate electrode connected to the first scan line, a first electrode connected to the fourth node, and a second electrode connected to the third node. A channel width of the second sub-transistor is wider than a channel width of the first sub-transistor.

Abstract: A display device includes a display panel, a driving circuit, and a power supply. The driving circuit is connected to a plurality of pixels of the display panel through a plurality of scan line sets and a plurality of data lines, provides a plurality of scan signals to the display panel, and provides data voltages to the plurality of data lines. The power supply applies one or more power voltages to the plurality of pixels. The driving circuit enables at least two scan signals of the plurality of scan signals during a non-emission interval, partially overlapping the at least two scan signals during at least two consecutive horizontal periods.

Abstract: An organic light-emitting display including a data driver connected to a plurality of data lines disposed in a first direction, a scan driver connected to a plurality of scan lines disposed in a second direction intersecting the first direction, and a display panel including a pixel group which includes first through fourth pixel units respectively connected to j-th through (j+3)-th data lines among the data lines. The first through fourth pixel units are connected to an i-th scan line among the scan lines and disposed in the first direction, where i and j are natural numbers equal to or greater than one.
