Abstract

An organic light emitting display device includes one or more pixels connected to scan lines, feedback lines, and data lines, and including driving transistors configured to control an amount of current supplied to organic light emitting diodes, a sensor configured to generate compensation data based on sensing data including deviation information of a driving transistor of the driving transistors and first reference data for a sensing period, a data driver configured to supply a first reference data signal to the data line based on second reference data for the sensing period, and a scan driver configured to supply a scan signal to the scan line, wherein the sensor is configured to generate the compensation data while changing a bit value of the second reference data two or more times during the sensing period.
