Claim Text:
1. An organic light emitting display device, comprising: a scan driving unit supplying a first scan signal and a second scan signal to each of a plurality of scan lines; a data driving unit supplying data signals to a plurality of data lines so as to be synchronized with the second scan signal; and a plurality of pixels positioned at intersections of the scan lines with the data lines, the pixels receiving a bias power when the first scan signal is supplied and receiving the data signals when the second scan signal is supplied, each of the pixels including: an organic light emitting diode; a first transistor connected to a first node and a second node, the first transistor controlling an amount of current supplied from a first power supply to the organic light emitting diode in accordance with a voltage difference between the first node and the second node; and a second transistor connected between the first node and an initiation power supply, wherein when an initiation power from the initiation power supply is applied to the first node and the bias power is applied to the second node, a voltage of the bias power is set so that an on-bias voltage is applied to the first transistor.
