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.

Abstract: A display device includes a display panel including pixels in one pixel column and a gate driver for sequentially providing scan signals to the pixels. Each of the pixels includes a light emitting element, a first transistor for controlling a current amount of driving current flowing through the light emitting element and a second transistor for transferring a data signal to a gate electrode of the first transistor in response to a corresponding scan signal among the scan signals. A first pixel among the pixels is electrically connected to a first data line, and a second pixel adjacent to the first pixel among the pixels is electrically connected to a second data line different from the first data line. A second scan signal provided to the second pixel partially overlaps with a first scan signal provided to the first pixel.
