According to the present invention, when the real-time sensing (OFF-RS) of an organic light emitting diode display device is executed, the whole horizontal line of a display panel to be processed through OFF-RS is divided into a plurality of sections. When RS is executed once, compensation data are calculated by sensing only selected section lines, and then, the calculated compensation data are updated in a lookup table. The compensation data, updated in the lookup table, are applied to the selected section lines. To the rest of the section lines, a control signal and data, employing previously stored compensation data, are generated and provided as a data driver. Thus, the organic light emitting diode display device is capable of effectively reducing time required for OFF-RS.
