Abstract: Provided herein may be an organic light emitting display device including: pixels coupled both to power source lines and scan lines that are formed on respective horizontal lines, and to data lines formed on respective vertical lines; a scan driver configured to supply scan signals to the scan lines; a first power source driver configured to supply first power sources to the power source lines; and a data driver configured to supply data signals to the data lines. The first power source driver may control light emitting operations of the pixels by successively stopping the supply of the first power sources to the power source lines.

Abstract: An organic light-emitting display device may include a first pixel, a first data line, a first scan line, a data driver, and a scan driver. The first pixel unit may include a sensing transistor and a scan transistor. The data driver may be electrically connected to the scan transistor through the first data line. The scan driver may be electrically connected to the scan transistor through the first scan line. The scan transistor may be turned on during a first period and a second period. The sensing transistor may be turned on during a third period between the first period and the second period. The first period, the second period, and the third period are included in one frame.

Abstract: An organic light emitting display includes a plurality of pixel row groups, a scan driver, a data driver, and a data distributor. Each pixel group includes the same number of pixel rows, and the pixel row groups are sequentially driven. The data distributor demultiplexes data signals for input into the pixels. The data signals are input to the pixels after threshold voltage compensation is performed at substantially a same time for pixels in each of the pixel row groups. Data signals are to be input to pixels in one pixel row group while threshold voltage compensation is performed for pixels in another pixel row group adjacent to the one pixel row group.
