Popis: Abstract Display has been evolving its role as a conventional optical output device into an user interactive input and output device by harnessing various sensors and taking full advantage of its user interaction friendly nature. To demonstrate this phenomenon, here we report a full organic photodiode embedded organic light-emitting diode display as multiple objects sensing platform which identifies the user’s physiological data based on the obtained photoplethysmography signal and also detects a fingerprint for an authentication concurrently in a single device. This paper introduces the technical breakthroughs to solve the complex technical challenges due to the crosstalks induced within the shared common layers during the full integration of the two conflicting devices and also the method made possible for the multiple objects sensing with the measurement results. Consequently, we believe it could prove a progression of display to a fully bidirectional innovative smart user interactive device and also could take a role as a sophisticated future display beyond organic light-emitting diode display.
