Patent abstract
An organic light emitting display device includes data lines, selection scan lines, and emission scan lines for transmitting data signals, selection signals, and emission signals, respectively. Pixel circuits are arranged at regions defined by the data lines and the selection scan lines. A first scan driving unit outputs the emission signals. The first scan driving unit includes conversion circuits, each of the conversion circuits including conversion circuit transistors of an identical channel type. Each of the conversion circuits receives a first signal, a second signal, a third signal and a conversion circuit clock signal, and outputs a conversion output signal as a respective emission signal of the emission signals.
