Pixel, organic light emitting display device including the same, and method of operating of the organic light emitting display device

An organic light emitting display device includes a plurality of data lines, a scan driver, a sensing control line driver, a data driver, and a switching unit. The scan driver supplies a scan signal to a plurality of scan lines. The sensing control line driver supplies a sensing control signal to a plurality of sensing control lines. The data driver supplies a data signal to a plurality of data output lines. The switching unit selectively couples each data line to one of a corresponding data output line and a corresponding sensing line. The switching unit further selectively supplies a write control signal to each write control line.
