An organic light emitting display includes a pixel unit having pixels coupled to scan lines, first control lines, second control lines, data lines, and first and second power sources, a control line driver for providing a first control signal and a second control signal to the pixels through the first control lines and the second control lines, a scan driver for providing scan signals to the pixels through the scan lines, and a data driver for providing data signals to the pixels through data lines. The scan driver simultaneously supplies a first scan signal to the pixels through the scan signals. In the organic light emitting display, deviation in the threshold voltages of the driving transistors included in the pixels is compensated without a power swing so as to display an image with uniform brightness.
