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.

Abstract: In an embodiment, an organic light emitting display device includes a first substrate, a display region, a pad portion, lines, and a moisture-transmission delay layer. The display region includes sub-pixels disposed on the first substrate. The pad portion is disposed on the first substrate and electrically connected to an external device. The lines are disposed between the pad portion and the display region and electrically connected to the external device, and transfer a signal or power to the external device. The moisture-transmission delay layer covers edges of the lines.
