Abstract
An organic light emitting display, and a driving method thereof are discussed. The organic light emitting display according to an embodiment includes a plurality of pixels sharing a sensing path, a first switch circuit configured to supply a sensing data voltage to the pixels sharing the sensing path through data lines in response to a first scan pulse, a second switch circuit configured to electrically connect an Organic Light Emitting Diode (OLED) of each of the pixels with the sensing path in response to a second scan pulse to simultaneously supply currents of the pixels to the sensing path in a sensing period, and a sensing circuit configured to sense a sensing value through the sensing path. The sensing path includes a reference voltage line connected to the pixels to provide the currents of the pixels to the sensing circuit. The pixels simultaneously sensed by the sensing circuit have a same sensing value.
