Abstract
An organic light emitting display device includes a display panel including pixel groups, each including a plurality of sub-pixels for each of pixel rows. A gate driver is configured to sequentially provide an initialization signal to the pixel rows, to provide a first group gate signal to first pixel groups of the pixel groups, to provide a second group gate signal overlapping at least a part of the first group gate signal to second pixel groups of the pixel groups, to sequentially provide the first group gate signal to the pixel rows, and to sequentially provide the second group gate signal to the pixel rows. An emission control driver is configured to sequentially provide an emission control signal to the pixel rows. A data driver is configured to output a data voltage. A data divider is configured to selectively provide the data voltage to data lines connected to the sub-pixels.
