An organic light emitting display comprises a display panel having data lines, scan lines, emission signal lines, and pixels. The display also comprises a data driver configured to provide a data voltage corresponding to an input image to one of the data lines connected to a pixel and a gate driver configured to provide an N-th scan pulse to an N-th scan line to charge the pixel with the data voltage during a scan period within a frame period. The display further comprises an emission driver configured to receives shift clocks and the N-th scan pulse from the gate driver to provide an N-th emission control signal to the N-th emission signal line and to control a current path through the OLED based on the N-th emission control signal during a duty driving period following the scan period within a frame period.
