Samsung: Unveils a rollable 12.4″ OLED panel

During the annual Display Week trade show in Los Angeles, Samsung unveiled a 12.4-inch scrollable OLED panel.

This isn’t the first time we’ve seen a rollable concept, but Samsung’s panel is a step ahead of the competition as it’s the largest yet and turns into a tiny scroll.

The panel can go from 49mm to 254.4mm, an impressive 5x expandability compared to current class monitors that can only grow up to 3x their original size. Samsung Display says it was able to achieve this by using an O-shaped axis that mimics a scroll. The company calls it the Rollable Flex, and it can be fully rolled up.

In addition to the Rollable Flex, Samsung introduced an OLED Flex In & Out panel, which can be bent in both directions, unlike the currently used technology that allows flexible OLEDs to be folded in only one direction.

It also introduced the world’s first OLED panel with a built-in fingerprint reader and heart rate sensor. The panel allows you to unlock the handset with a touch of the finger anywhere on the screen surface, incorporating the organic light-sensing photodiode (OPD). The technology can also read blood pressure, heart rate and stress by monitoring the constriction and relaxation of blood vessels.
