Samsung have showcased a new “potentially revolutionary” 12.4-inch rollable OLED panel, rolling out as the largest one so far and just in a tiny scroll.

This panel will be able to change from 49mm to 254.4mm, showcasing a 5x scalability compared to current ones that showcase a 3x scalability to their original size.

Samsung claims this was achievable using an O-shaped axis that mimics a scroll. It is being dubbed the Rollable Flex, and is able to be completely rolled.

Samsung have also announced a Flex In & Out OLED panel, able to bend in both directions, just like the Galaxy Flip4 and Fold4.

As well, they have also introduced the first OLED panel with an integrated fingerprint reader and heart rate sensor.

This will allow users to unlock the handset with a touch of a finger anywhere on the screen. It comes with light-sensing organic photodiode (OPD), and can read blood pressure, heart rate and stress just by monitoring the blood vessels’ contraction and relaxation.
