Abstract: A display device is disclosed that includes a plurality of pixels and a plurality of code pixels. The pixels include light-emitting elements, which display an image. The code pixels are disposed in the same layer as the pixels and are adjacent to a reference point disposed between the pixels. The code pixels include infrared light-emitting elements, which emit infrared light. At least one of the code pixels, disposed in a particular direction from the reference point, emit the infrared light to provide a code pattern having position information.
