Abstract: An organic light emitting display device includes a display panel including pixels that includes an organic light emitting diode that emits light based on a driving current, a data driver providing a data signal to the pixels through a data line, a scan driver providing a scan signal to the pixels through a scan line, an emission control driver providing an emission control signal to the pixels through an emission control line, a first power provider providing a first high power voltage to the pixels through a first power providing line and a second power provider providing a second high power voltage to the pixels through a second power providing line and coupled to the first power provider. The second power provider includes a static current circuit that maintains the driving current having uniform value when the display panel is operated in a low frequency driving mode.
