Abstract

An OLED panel may be embedded with a near-infrared organic photosensor and may be configured to implement biometric recognition without an effect on an aperture ratio of an OLED emitter. The OLED panel may include a substrate, an OLED stack on the substrate and configured to emit visible light, and an NIR light sensor stack between the substrate and the OLED stack and including an NIR emitter configured to emit NIR light and an NIR detector. The OLED panel may be included in one or more various electronic devices.
