In the recent advance of mobile phone technology, touch panel and finger print sensor has become one of the most crucial component in the display panel integration. In order to realize a full‐screen finger print sensor, the sensor should be fully transparent toward the visible light, thus not affecting the light emission of the LCD/OLED arrays. Here, we present a visibly transparent organic photosensor with high photosensitivity toward near‐IR spectrum from 800 to 100 nm. The photosensor is realized through the utilization of organic semiconductor and solution‐processed silver nanowire electrode, making it a low‐cost and superior choice for the future display application.
