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.

Abstract: A display device includes: a display panel including pixels connected to compensation gate lines, and a compensation gate driver which supplies compensation gate signals to the display panel. The compensation gate driver includes: a first compensation gate driver which generates the compensation gate signals based on a first-first clock signal and a second-first clock signal and a second compensation gate driver which generates the compensation gate signals based on a first-second clock signal and a second-second clock signal. The first-first clock signal and the second-first clock signal have the same waveform as the first-second clock signal and the second-second clock signal, respectively, during a scan period in which a compensation gate signal is supplied to the display panel, and have different waveforms from the first-second clock signal and the second-second clock signal, respectively, during a blank period in which the compensation gate signal is not supplied to the display panel.
