摘要： A system on panel (SOP)-type scan driver for an organic light emitting display (OLED) device. The scan driver includes flip-flops. Each of the flip-flops receives an input signal, a clock signal, and an inverted clock signal and outputs a scan signal. The scan signal is shifted and input to an adjacent flip-flop. Each of the flip-flops includes three transistors of the same conductivity type and a capacitor. Thus, layout area is minimized owing to simplification of circuits, and static current is cut off to reduce power consumption.
