    Abstract: Disclosed is an organic light emitting diode (OLED) display including a plurality of pixels, first and second scan signal stages, and emission control signal stages. The pixels are respectively arranged along n number of lines (n is a natural number), and each of the pixels include a first scan transistor, a driving transistor, a second scan transistor, and an emission control transistor. The first scan signal stages output first scan signals sequentially to the first scan transistors. The second scan signal stages output second scan signals sequentially to the second scan transistors. The emission control signal stages output emission control signals having a same phase to emission control transistors of two adjacent horizontal lines.

    Abstract: Provided are a pixel, a display device including the same, and a driving method thereof. A pixel includes: an organic light-emitting diode including an anode and a cathode, a first transistor configured to provide a driving current flowing through the organic light emission diode, a second transistor configured to provide data to a gate of the first transistor in response to a scan signal, a capacitor configured to maintain a difference between a voltage level of the data and a threshold voltage of the first transistor, and a third transistor configured to: sense a change of the threshold voltage of the first transistor in response to a sensing signal, and transfer a reference voltage to a node coupled to the anode when the sensing signal is enabled, wherein a level of the reference voltage is lower than a threshold voltage of the organic light-emitting diode.

    Abstract: Disclosed is an Organic Light Emitting Diode (OLED) display including pixels and a shift register for driving transistors arranged in the pixels. The pixels include a first group of pixels disposed on a first row, and a second group of pixels disposed on a second row. The shift register applies a first scan signal to the first group of pixels and the second group of pixels simultaneously. In addition, the shift register applies a second scan signal to the first group of pixels and the second group of pixels sequentially.

    Abstract: A display device includes a substrate including a plurality of sub-pixels; a planarization layer disposed on the substrate and including a trench adjacent to the plurality of sub-pixels; a plurality of light emitting elements disposed in the plurality of sub-pixels and sharing an organic layer and a cathode; and an auxiliary electrode disposed in the trench and connected to the cathode. A side surface of the auxiliary electrode has a concave shape. The organic layer has an open portion that is disconnected by the auxiliary electrode. Therefore, it is possible to minimize current leakage through the common layer and prevent an increase in resistance of the cathode by the auxiliary electrode.
