Abstract
An organic light emitting display device includes pixels divided by scan lines and data lines, and including first transistors for controlling the amount of current flowing from a first power source to a second power source through organic light emitting diodes, first feedback lines and second feedback lines formed in parallel to the data lines, control lines formed in parallel to the scan lines, and a sensing unit configured to extract at least one of voltage drop of the first power source and deterioration information of the first transistor from the pixels via the first feedback lines and the second feedback lines.
