Abstract: A display device can include a plurality of sub pixels disposed on a substrate; a first driver disposed in each of the plurality of sub pixels, the first driver being configured to generate a first driving current for a normal mode in which an image is displayed in a luminance range equal to or lower than a predetermined luminance; a second driver disposed in each of the plurality of sub pixels, the second driver being configured to generate a second driving current for a high luminance mode in which the luminance range is higher than the predetermined luminance; and a light emitting diode. Also, the light emitting diode is configured to receive the first driving current in the normal mode, and receive a sum of the first driving current and the second driving current in the high luminance mode.

Abstract: A display device in one example includes a display panel having pixels on a substrate being divided into a first area at a center area and a second area adjacent to the first area. The display panel further includes a gate driver having stages configured to supply a gate signal to the pixels through gate lines. Each of the stages included in the gate driver is disposed in a gate area that at least partially overlaps the first area and the second area. The pixels include first pixels disposed on the first area and second pixels disposed on the second area. Further, the first pixels can be disposed in the first area at a first density and the second pixels can be disposed in the second area at a second pixel density being lower than the first pixel density.
