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.
