  • Patent number: 9041633
    Abstract: An organic light emitting display device includes a display unit having pixels located at crossing regions of scan, control, data and sensing lines. Scan, control line, and data drivers respectively supply scan, control, and data signals to the scan, control, and data lines. A switching unit selectively couples the data lines to output lines of the data driver, a reference voltage source, or a negative bias voltage source. A sensing unit senses degradation information of an organic light emitting diode in the pixels and threshold voltage of a driving transistor in the pixels through the sensing lines. A control block stores the sensed degradation information and threshold voltage information. A timing controller is configured to generate a second data by converting an externally inputted first data using the degradation information and the threshold voltage information, and supply the second data to the data driver.
