Abstract
An organic light emitting display includes a mode determining unit adapted to determine whether the display is in a low power or common driving mode based on an operation control signal and to generate a control signal corresponding to the determined mode, a scan driver adapted to sequentially supply scan signals to scan lines, a data driver adapted to supply data signals to data lines in synchronization with the scan signals, pixels arranged at intersections of the scan lines and the data lines, and a timing controller adapted to control the scan driver and the data driver so that a frame frequency changes based on whether the low power driving mode or the common driving mode control signal is supplied from the mode determining unit, wherein the scan driver is adapted to uniformly maintain a pulse width of the scan signals regardless of a change in the frame frequency.
