PURPOSE: An organic light emitting display device is provided to display an image of desired brightness by compensating the deterioration of the organic light-emitting diode and the threshold voltage and mobility of a driving transistor. CONSTITUTION: In an organic light emitting display device, pixels are installed at intersection of scanning lines(S1~Sn), luminous control lines(E1~En), and data lines(D1~Dm) A sensing part(180) extracts the deterioration state of the organic light-emitting diode and extracts the threshold voltage and mobility of the driving transistor. A transform unit(190) changes the bit of input data and generates correction data. A data driver(120) generates a data signal. The data driver supplies a specific data signal to the data lines.
