Abstract

We present large-area photodetector arrays in combination with a thin-film optical collimator for under-display fingerprint authentication in next-generation smartphones. The fabrication is compatible with flat panel display processes and based on an oxide TFT backplane with a printed organic photodiode frontplane. The functionality behind an AMOLED display is demonstrated.
