15. A display panel, comprising:
a substrate;
a driver stack on the substrate, the driver stack including a transistor array;
a light emitter stack on the substrate and the driver stack, the light emitter stack including a red sub-pixel, a green sub-pixel, and a blue sub-pixel, each of the red, green, and blue sub-pixels configured to emit light; and
a light sensor on the substrate and the driver stack, the light sensor configured to detect at least a portion of the emitted light based on reflection of the portion of the emitted light from a recognition target,
wherein the red sub-pixel, the green sub-pixel, the blue sub-pixel, and the light sensor are arranged in a horizontal direction extending parallel to an upper surface of the substrate.
