Patterning organic materials by photolithography enables not only high-resolution, side-by-side RGB OLED arrays, but also the introduction of organic photodetector in the same frontplane. We show patterned active matrix displays processed on flexible backplane. Furthermore, we demonstrate OPD patterning proof-of-concept These are the building blocks allowing in-cell opticalfingerprint sensor.
