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.

Abstract: A display device includes a light sensing array layer (LSAL), a substrate, a selective light transmission layer (SLTL), a pixel circuit layer (PCL), a display element layer (DEL), and pixels. The LSAL includes an optical sensor to sense incident light. The substrate is on the LSAL and includes a display area (DA) including pixel areas (PAs), and a non-DA adjacent to the DA. The SLTL is disposed on the substrate and includes through-holes to form a path of light onto the optical sensor, and a light-blocking conductive pattern (LBCP) between the through-holes. The PCL is disposed on the SLTL and includes a conductive layer and an insulation layer. The DEL is disposed on the PCL and emits light. Each pixel includes a pixel circuit disposed on the PCL, and a light emitting element on the DEL in a corresponding pixel area. The LBCP is electrically connected to the conductive layer.
