Abstract:
1. An organic light emitting display device comprising: a plurality of data lines adapted to transmit a plurality of data signals; a plurality of selection scan lines adapted to transmit a plurality of selection signals; a plurality of emission scan lines adapted to transmit a plurality of emission signals; a plurality of pixel circuits arranged at regions defined by the data lines and the selection scan lines; and a first scan driving unit adapted to output the emission signals, wherein: the first scan driving unit comprises a plurality of conversion circuits, each of the conversion circuits comprising a plurality of conversion circuit transistors of an identical channel type, being adapted to receive a first signal, a second signal, a third signal and a conversion circuit clock signal, and being adapted to output a conversion output signal as a respective emission signal of the emission signals, when the conversion circuit clock signal and the first signal are enable, the conversion output signal is disable, when the conversion circuit clock signal, the first signal and the third signal are disable and the second signal is enable, the conversion output signal is disable, when the conversion circuit clock signal, the first signal and the third signal are enable, the conversion output signal is disable, and when the first signal is disable and the conversion circuit clock signal and the third signal are enable, the conversion output signal is enable.
