Samsung shows off several exciting displays including one that expands more than 5 times

The Sensor OLED Display can recognize fingerprints anywhere on the display while monitoring a user’s heart rate, blood pressure, and more

A spokesperson for Samsung Display said, “To accurately measure a person’s blood pressure, it is necessary to measure the blood pressure of both arms. The Sensor OLED display can simultaneously sense the fingers of both hands, providing more accurate health information than existing wearable devices.”

Another display that Samsung has on, uh, display at the event, is called Rollable Flex. It expands from 49 mm to 254.4 mm, an increase of over five times! About this display, Samsung says, “While conventional foldable or slidable form factors offer up to three times the scalability, Rollable Flex overcomes such limitations by enabling the display to be rolled and unrolled on an O-shaped axis like a scroll.” A spokesman added, “The biggest feature is that we were able to turn a difficult-to-carry large-sized display into a portable form factor by making it rollable,”

A fascinating display that Samsung calls Flex In & Out is designed for a foldable smartphone. It can be folded both inward and outward 360 degrees. This can eliminate the necessity of including an external “cover screen” that is needed on inward-closing foldables like the Galaxy Z Fold 4. As a result, such devices can be made lighter and thinner.

It isn’t clear how long it will take before any of these screens are found in devices available for purchase. Samsung Display says, “We look to show that the paradigm of the display industry can evolve once again at SID, where industry players, media, and consumers come together. Visitors can see our vision of the future OLED industry through our technology.”
