During the annual Display Week trade show in Los Angeles, Samsung showcased a potentially revolutionary 12.4-inch rollable OLED panel. Surely, this isn't the first time we see a rollable concept, but Samsung's invention is a step ahead of the competition as it's the largest one so far and it rolls in a tiny scroll. The panel can go from 49mm to 254.4mm, that's an impressive 5x scalability compared to the current sliding screens that can only go up to 3x their original size. Samsung Display says it was able to achieve this by using an O-shaped axis mimicking a scroll. The company calls it Rollable Flex and can be completely rolled.
In addition to the Rollable Flex, Samsung
introduced a Flex In & Out OLED panel, which can bend in both directions,
unlike the currently used tech that allows the flexible OLEDs to fold in just
one direction. Case in point, Samsung's very own Galaxy Flip4 and Fold4.
Last, but not least, the Korean tech giant
also introduced the world's first OLED panel with an integrated fingerprint
reader and heart rate sensor. Current implementations rely on a small sensor
area while Samsung's solution allows you to unlock the handset with a touch of
a finger anywhere on the screen surface. It has embedded the light-sensing
organic photodiode (OPD) into the panel itself. The tech can also read blood
pressure, heart rate and stress by monitoring the blood vessels' contraction
and relaxation.
