Samsung has unveiled a new display technology that could lead to new biometric and health-related capabilities in future phones and tablets. The tech giant debuted what it calls a Sensor OLED Display that can read your fingerprints no matter which part of the screen you touch at this year’s SID Display Week in LA. While most smartphones today have fingerprint readers on the screen, their sensors are included under the panel as a separate module that only works within a small designated area. For Sensor OLED, Samsung says it has embedded the fingerprint sensor in the panel itself.
Since the display technology can read fingerprints anywhere on the screen, it can also be used to monitor your heart rate and blood pressure. The company says it can even return more accurate readings than available devices. To measure your blood pressure, you need to place two fingers on the screen. OLED light is apparently displayed differently depending on the contraction and relaxation of your blood vessels. After returning that information to the panel, the sensor converts it into health metrics.
Samsung explained in its press release: “To accurately measure a person’s blood pressure, it is necessary to measure the blood pressure in both arms. .” The company has not yet announced whether it plans to use this new technology in the devices it will release in the future, but the SID Display exhibit already shows that it can read blood pressure and heart rate.
In addition to Sensor OLED, Samsung also showed the Rollable Flex screen that can expand more than five times the height when opened. Meanwhile, its Flex In & Out concept phone features a Galaxy Fold-like device that you can fold vertically inward or outward. This eliminates the need for an external display, which could lead to thinner foldable phones.
