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: A gate driver and a display device including the same are disclosed. The gate driver includes a plurality of stages. Each stage includes a first transistor outputting a first clock signal as a scan signal in accordance with a first node, a second transistor outputting a gate-off voltage as the scan signal in accordance with a second node which is activated as opposed to the first node, a first controller activating the first node to a gate-on voltage in response to a start signal or a carry signal and a fourth clock signal, and a second controller activating the second node to the gate-on voltage in response to a second clock signal and a third clock signal.
