An organic light emitting display device includes: pixels at crossing regions of scan lines, light emission control lines, sensing lines, and data lines; a sensor configured to extract deterioration information from organic light emitting diodes included in the pixels during a first sensing period and to extract threshold voltage and mobility information of driving transistors included in the pixels during a second sensing period; a converter configured to generate corrected data by changing input data based on the deterioration information and the threshold voltage and mobility information; and a data driver configured to supply data signals, the data signals being based on the corrected data during a driving period and being reference data signals during the second sensing period, wherein the sensor is configured to extract the threshold voltage and mobility information of the driving transistors using second electric currents from the pixels in response to the reference data signals.
