Display stack with integrated photodetectors

An electronic device, comprising:

• a display stack including,
• an exterior structural component;
• an array of organic light-emitting diodes (OLEDs) disposed below the exterior structural component and including an array of emissive electroluminescent (EL) regions, the array of OLEDs operable to generate an electronic image that is viewable through the exterior structural component;
• and
• an array of organic photodetectors (OPDs) disposed below the array of OLEDs, wherein an emissive EL region of the array of EL regions overlaps an OPD in the array of OPDs;
• wherein,
• the array of OPDs has a material construction configured to absorb electromagnetic radiation in at least a first range of electromagnetic radiation wavelengths outside a second range of electromagnetic radiation wavelengths emitted by the array of OLEDs;
• a material positioned between the array of OLEDs and the array of OPDs is configured to reflect the second range of electromagnetic radiation wavelengths;
• and
• the first range of electromagnetic radiation wavelengths and the second range of electromagnetic radiation wavelengths are non-overlapping.
