Abstract: An electronic device includes a frame and a display stack. The frame defines a first part of an interior volume. The display stack includes a cover attached to the frame. The cover may define a second part of the interior volume. The display stack also includes an array of organic light-emitting diodes (OLEDs) including an array of emissive electroluminescent (EL) regions, and at least one organic photodetector (OPD) disposed between the cover and at least one emissive EL region in the array of emissive electroluminescent regions. The at least one emissive EL region emits light through the at least one OPD. In alternative embodiments, the OLEDs may be stacked on the OPDs, or the OLEDs and OPDs may be interspersed with each other instead of stacked.
