An organic light emitting display includes: scan lines for applying scan signals; control lines for applying control signals; and data lines for applying data signals. The organic light emitting display further includes: pixels coupled to the scan, control and data lines for displaying an image; power supply lines coupled to the pixels; and a data driver for supplying the data signals of the image to the data lines. The organic light emitting display also includes: a power supply driver for swinging a voltage at the power supply lines between a first level and a second level; a sensing unit including a current sink for sinking a first current from the pixels and a current source for supplying a second current to the pixels; and a switching unit for selectively electrically coupling the pixels to at least one of the data driver, the current source or the current sink. |
