Organic light emitting display device and method of driving the same

An organic light emitting display device comprising:

• pixels at crossing regions of data lines and scan lines, each of the pixels comprising an organic light emitting diode (OLED);
• a scan driver configured to drive the scan lines;
• a data driver configured to drive the data lines;
• a control line driving unit configured to drive control lines during a sensing period for extracting pixel information comprising at least one of deterioration information of the OLED or threshold voltage information of a driving transistor from each of the pixels;
• and
• a compensation unit configured to extract the pixel information from each of the pixels including a first one of the pixels and a second one of the pixels during the sensing period, the first and second ones of the pixels being coupled to a first one of the data lines,
• wherein, during the sensing period, the data driver is further configured to:
• supply a white data signal to each of the pixels coupled to the first one of the data lines other than the first one of the pixels and supply a specific data signal different from the white data signal to the first one of the pixels before the extracting of the pixel information from the first one of the pixels;
• and
• supply the white data signal to each of the pixels coupled to the first one of the data lines other than the second one of the pixels and supply the specific data signal to the second one of the pixels after the extracting of the pixel information from the first one of the pixels and before the extracting of the pixel information from the second one of the pixels.
