Abstract
An organic light-emitting diode (OLED) display includes an array of OLED pixels and an array of organic photodetector (OPD) pixels. 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. 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. In other embodiments, the OPD pixel may be configured differently.
