Abstract: An organic light emitting display device includes: a plurality of pixel regions. Each of the pixel regions includes: a first transistor configured to apply a data voltage on a first adjacent data line to a first node in response to a scan signal on the primary scan line; a second transistor configured to apply the data voltage on the first adjacent data line to the first node in response to a sensing signal on the secondary scan line; and a third transistor configured to detect a sensing voltage and apply the sensing voltage to a second adjacent data line, The data driver compares the sensing voltage and the data voltage and compensates for the data voltage of next frame, and the scan signal and the sensing signal are generated in different intervals of a single frame.
