Abstract: A display device includes: a display panel having a first region and a second region defined in the display panel, in which the second region is adjacent to the first region in a first direction. The display panel includes: a first pixel disposed in the first region, a second pixel disposed in the second region, a first bias voltage line electrically connected to the first pixel to transmit a first bias voltage, and a second bias voltage line electrically connected to the second pixel to transmit a second bias voltage. A time point, at which a level of the first bias voltage is changed, differs from a time point at which a level of the second bias voltage is changed, when the display panel operates at a first frame frequency.

Abstract: A display device includes a display panel including a pixel connected to scan lines and a data line, a scan driving circuit, a data driving circuit, and a driving controller that controls the scan driving circuit and the data driving circuit. The pixel includes a light-emitting diode and an initialization transistor connected between a first initialization voltage line and a first electrode of the light-emitting diode and including a gate electrode connected to a first scan line among the scan lines. A first scan signal provided to the first scan line during a blank period has an active level during a predetermined initialization time duration, and the predetermined initialization time duration is set to a time duration corresponding to a luminance characteristic of the display panel.
