摘要： 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.
