Abstract:
1. An organic light emitting display device comprising: a scan driver for driving a scan line and a light emitting control line, the scan line and the light emitting control line being formed parallel to each other; a data driver for driving a data line formed at a direction crossing the scan line and the light emitting control line; a pixel disposed to be coupled with the scan line, the light emitting control line, and the data line; an auxiliary line formed parallel to the data line and crossing the scan line and another scan line, one side of the auxiliary line being coupled with a reference power supply and another side of the auxiliary line being coupled with a current source; a connector disposed at a crossing area of the auxiliary line and the scan line, the connector comprising a transistor having a gate electrode coupled with the scan line; and a voltage transfer unit coupled with the connector for transferring a voltage supplied to the connector to the data driver, the voltage supplied from the voltage transfer unit to the data driver being set to a value obtained by subtracting a voltage value of a voltage drop of the auxiliary line from a voltage value of the reference power supply, wherein the data driver is coupled with the data line during a first period of one horizontal period, and the data driver is configured to receive a predetermined current from the pixel selected according to a scan signal and to reset a voltage value of a data signal using a compensation voltage generated when the predetermined current is received during the first period, and wherein the data driver is configured to provide the voltage value of the data signal to the pixel during a second period of the one horizontal period, the second period being a period other than the first period.
