Samsung Display, like other major display manufacturers, is participating in the SID Display Week 2023 conference in Los Angeles this week. And it offers some interesting news, especially prototypes and conceptual designs on flexible screens that we will be able to see in commercial solutions in the coming years.

We liked it the most Rolling Flex. It’s a 49mm screen that can be wind and unwind vertically up to 254mm with O-shaped shaft.

When extended, the screen can be used as a monitor. Once packed, it can be used as a mobile device, be it a laptop or an electronic tablet. Very cool, but as always with this type of prototype, you have to wait until you see its effective application in a product that we can use. And pay… because these technologies are not cheap, because we “suffer” in folding smartphones.

Another new screen, aimed at portable devices, is called OLED sensor, which can recognize fingerprints anywhere on the panel. This differs from displays currently sold, which have fingerprint sensors as modules attached under the panel in specific areas.

Here, light detection sensors have been built into the entire screen and serve other purposes. These sensors are able to read the light reflected from the contraction and relaxation of blood vessels in the fingers of both hands as they touch each other and translate it into health information including heart rate, blood pressure and stress levels.

More news will come from FlexHybrid. First announced at CES, it’s a 10-inch screen that adds the best of both worlds in terms of flexible panels, being both foldable and sliding over 12 inches. It is stylus compatible and designed for use on laptops.

Rounding out the showcase of new display technologies, Samsung Display will also introduce Flex In & Out, a panel that can be folded and unfolded 360 degrees.

This new concept phone format “folded”, requires a separate external panel to display information in a folded state. But it has the advantage that thinner and lighter folding phones can be produced.
