SID Display Week is the ideal place to show off new display innovations, and this year Samsung Display came prepared. Samsung’s South Korean screen subsidiary unveiled an OLED display on Monday with built-in cardiovascular and fingerprint sensors, allowing both readings to occur anywhere on the screen.
Most devices have designated sensor spots, meaning you must tap or rest your finger on a specific part of the device to get a reading. These sensors typically comprise their own module and are placed under the display panel, offering the illusion that the sensors are built into the screen. Samsung Display’s new “Sensor OLED” takes this illusion and turns it into reality. By embedding a light-sensing organic photodiode (OPD) into the display panel, Samsung Display has enabled users to scan their fingerprints, track their heart health anywhere on the screen, and even read both simultaneously.

Samsung Display says that obtaining an accurate blood pressure reading requires both arms. (Because hardware companies aren’t the be-all and end-all of medical advice, you might be pleased to know that the American Heart Association says the same thing.) Rather than having a user obtain one arm’s blood pressure score and then the other, the Sensor OLED allows the user to place one finger from each hand on the display. The built-in sensor can then pull readings from both fingers simultaneously. Samsung Display says the sensor can also measure the user’s heart rate and “stress level,” though it’s unclear exactly what biometric data it’s using to refer to the latter measurement.
Though there’s never a guarantee that technology introduced at a convention will appear on shelves, it’s hard to imagine why Samsung wouldn’t eventually put the Display OLED on its phones. It showed off other explicitly smartphone-related tech: The new “Flex In & Out” display can be folded both inward and outward 360 degrees, creating the potential for an even bendier Samsung Galaxy Z Fold or Galaxy Z Flip. Samsung Display also shared its scroll-like roll-up display called “Rollable Flex,” a 77-inch QD-OLED TV, and two QD-OLED desk monitors.
