Abstract: A display device can include a substrate including a display area and a non-display area. The display device can further include a plurality of light-emitting elements disposed on the substrate, and a sealing layer disposed on the plurality of light-emitting elements. The display device also can include a touch detection part disposed on the sealing layer in the display area, and a plurality of touch routing lines connected to the touch detection part in the non-display area. Further, the display device can include a shield part disposed to surround two opposite sides and a lower side of one or more touch routing lines among the plurality of touch routing lines.

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.
