Abstract

A display device including a plurality of pixels disposed on a substrate, wherein each pixel includes a first subpixel, a second subpixel adjacent to the first subpixel, and a third subpixel adjacent to the second subpixel. Further, each of the first subpixel and the third subpixel include a single light emitting diode corresponding to a single light emission region, and the second subpixel includes a first light emitting diode corresponding to a first sub-emission region, and a second light emitting diode corresponding to a second sub-emission region. The display device also includes a controller configured to control only the first light emitting diode of the second subpixel to emit light during a low gray level mode, and control the first light emitting diode and the second light emitting diode of the second subpixel to both emit light in a high gray level mode.
