    Abstract: An OLED panel for implementing biometric recognition influencing an aperture ratio of an OLED light emitter i includes a substrate, an OLED on the substrate, and a driver on the substrate. The OLED may emit visible light, and the driver may drive the OLED. The driver may include a visible light sensor configured to detect the visible light emitted by the OLED, and the visible light sensor may overlap the OLED in a direction that is substantially perpendicular to an upper surface of the substrate. The OLED panel may include a near infrared ray OLED that is configured to emit near infrared rays, and the driver may include a near infrared ray sensor configured to detect near infrared rays emitted by the near infrared ray OLED. The near infrared ray sensor may overlap the OLED in a direction that is substantially perpendicular to an upper surface of the substrate.

    Abstract: A photoelectric diode includes a first electrode and a second electrode facing each other; a photoelectric conversion layer between the first electrode and the second electrode, and a compensation layer on the photoelectric conversion layer, the compensation layer being configured to compensate absorption and reflection of light. The photoelectric conversion layer is associated with a first optical spectrum having a light-absorption peak at a first wavelength and a reflection peak at a second wavelength, the first wavelength and the second wavelength both within a wavelength region of about 750 nm to about 1200 nm. The photoelectric diode is associated with a second optical spectrum having a light-absorption peak at a third wavelength, the third wavelength is within the wavelength region of about 750 nm to about 1200 nm, the third wavelength different from the first wavelength.
