    Abstract: An organic light emitting display device includes: a first pixel region including first pixels coupled to first and second scan lines, and emission control lines; a first scan driver which supplies a first scan signal to each first scan line; a second scan driver which supplies a second scan signal to each second scan line; and an emission driver which supplies a light emission control signal to the emission control lines. The organic light emitting display device is in a second mode when the organic light emitting display device is mounted in a wearable device, and in a first mode otherwise. The second scan driver supplies k second scan signals to each second scan line in the first mode, and supplies j second scan signals to each second scan line in the second mode, where j is greater than k.
