Samsung Display shows its latest flexible OLEDs at Display Week 2023 and unveils the OLED Sensor Display
Samsung Display demonstrated many OLED technologies at Display Week 2023, which we'll detail below. It seems that the main new technology was the Sensor OLED Display, which is an OLED with an embedded sensor that can perform fingerprint sensing in addition to blood pressure, heart rate sensing and stress level sensing (all from reading the finger), which the company says is the first such display in the world.
The Sensor OLED Display embeds light-sensing organic photodiodes (OPDs) inside the display itself, which allows it to perform the sensing functions all over the display. Samsung explains that as OLED light is reflected differently depending on the contraction and relaxation of the blood vessels inside the finger, the OPD senses the light when it returns to the panel, and converts it into health information.
