    Abstract: An organic light emitting display device includes a controller to control a first area and a second area of a display based on a predetermined condition. The controller simultaneously controls the pixels in the first area to display an image and controls the pixels in the second area to display light having a same gray scale value. The predetermined condition may be a user command or an operational condition, power mode, or status of a host device. The same gray scale value may be a lowest gray scale value in a predetermined range. The first and second areas may have different contours, and may be located at respective main and peripheral display locations of the host device.

    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.
