    Abstract: An image sensor may include a photodiode within a semiconductor substrate and configured to sense light in an infrared wavelength spectrum of light, a photoelectric conversion device on the semiconductor substrate and configured to sense light in a visible wavelength spectrum of light, and a filtering element configured to selectively transmit at least a portion of the infrared wavelength spectrum of light and the visible wavelength spectrum of light. The filtering element may include a plurality of color filters on the photoelectric conversion device. The photoelectric conversion device may include a pair of electrodes facing each other and a photoelectric conversion layer between the pair of electrodes and configured to selectively absorb light in a visible wavelength spectrum of light. The filtering element may be between the semiconductor substrate and the photoelectric conversion device and may selectively absorb the infrared light and selectively transmit the visible light.

    Abstract: An OLED display panel may include a substrate, an OLED light emitter on the substrate and configured to emit light, and a visible light sensor on the substrate and 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. The visible light sensor is in a non-light emitting region adjacent to the OLED light emitter so as to be horizontally aligned with the OLED light emitter in a horizontal direction extending parallel to an upper surface of the substrate, or between the substrate and a non-light emitting region adjacent to the OLED light emitter such that the visible light sensor is vertically aligned with the non-light emitting region in a vertical direction extending perpendicular to the upper surface of the substrate.
