Samsung is showing off several exciting new displays at SID Display Week including one that captures fingerprints anywhere on the screen.
Samsung is reportedly working on a new technology that will allow an OLED panel to scan a fingerprint from anywhere on the screen. It was one of the projects that Samsung Display revealed at SID (Society for Information Display) Display Week 2023 which started today and runs through May 25th at the Los Angeles Convention Center. The Sensor OLED Display recognizes fingerprints using a light-sensing organic photodiode (OPD) that is embedded into the panel itself. Currently, a separate sensor attached to the panel is used but requires the user to press a specific area.
The Sensor OLED Display can also monitor the user’s user’s heart rate, blood pressure, and stress level with the touch of two fingers on the screen. Samsung explains that « OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, and when it returns to the panel, the OPD recognizes it and converts it into health information.
