Abstract: A stage circuit includes a first substage circuit unit connected to first through third input terminals receiving a start signal, a first clock signal, and a second clock signal, respectively. The first substage circuit unit generates first and second operation signals based on the start signal and the first and second clock signals, and supplies a first scan signal to a first output terminal based on the first and second operation signals. The stage circuit further includes a second substage circuit unit connected to the third input terminal and a fourth input terminal receiving a third clock signal. The second substage circuit unit supplies a second scan signal to a second output terminal based on the first and second operation signals, the second clock signal, and the third clock signal. The first and second scan signals include a pulse of a low voltage level and a high voltage level, respectively.

Abstract: An organic light emitting display device includes a pixel, a data line, a first scan line, a second scan line, and a scan driver. The pixel includes a first transistor, a second transistor, and a third transistor. A source of the first transistor is electrically connected to a drain of the third transistor. A source of the second transistor is configured to receive an initialization voltage. The data line is electrically connected to a source of the third transistor and may transmit a data voltage higher than the initialization voltage. The first scan line is electrically connected to a gate of the third transistor. The second scan line is electrically connected to a gate of the second transistor. The scan driver may provide an initializing scan signal to the second scan line at least two horizontal periods before providing an initial scan signal to the first scan line.
