Abstract: An organic light emitting diode display is discussed. The organic light emitting diode display includes a display area, in which first scan lines, second scan lines, and emission lines are disposed to intersect data lines, and pixels are disposed in a matrix, a data driver supplying a data voltage to the data lines, and a shift register supplying a first scan signal to the first scan lines, supplying a second scan signal to the second scan lines, and supplying an emission control signal to the emission lines. The shift register includes first scan signal stages sequentially supplying the first scan signal to pixels arranged on two adjacent horizontal lines, second scan signal stages sequentially supplying the second scan signal to the pixels, and an emission control signal stage simultaneously supplying the emission control signal to the pixels.

Abstract: An organic light emitting display comprises a display panel having a plurality of pixels, a gate drive circuit that drives scan lines and emission lines on the display panel, and a data drive circuit that drives data lines on the display panel, (n−1)th and nth pixels arranged in a row, a transistor array having a driving transistor, a sampling transistor, and a first initial transistor, and a capacitor connected between an initial voltage input terminal and the sampling transistor. A gate electrode of the first initial transistor for initializing the driving transistor of the nth pixel is connected to a scan line in the (n−1)th pixel.
