Patent ID: 8902207

Claim:
An organic light emitting display, comprising: a mode determiner adapted to determine whether the organic light emitting display is in a low power driving mode or a 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 a first scan signal and a second scan signal to corresponding scan lines coupled to respective pixels of the organic light emitting display; 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 determiner, wherein the scan driver is adapted to maintain a substantially uniform pulse width of the scan signals regardless of a change in the frame frequency by controlling a distance between an end of the first scan signal and a start of the second scan signal to be supplied through the corresponding scan lines based on the change in the frame frequency.
