1. An organic light-emitting diode (OLED) display, comprising:
an array of OLED pixels, wherein an OLED pixel in the array of OLED pixels includes,
an OLED hole transport layer (HTL);
an OLED electron transport layer (ETL); and
an emissive layer positioned between the OLED HTL and the OLED ETL; and
an array of organic photodetector (OPD) pixels, wherein an OPD pixel in the array of OPD pixels includes,
the OLED HTL;
the OLED ETL; and
an electron donor material positioned between the OLED HTL and the OLED ETL, wherein the OLED ETL functions as an electron acceptor material for the OPD pixel.
