As a fan of foldable tech, I couldn’t pass up the opportunity to check out the Samsung Display booth at MWC. I was hoping to get a glimpse into the future of foldable OLED technology during my visit, and thankfully, Samsung didn’t disappoint.
The Korean vendor showed off more foldable concepts than I thought they would. Some were expected, like the In & Out screens that let a foldable fold both ways. Others were newer, like rollable OLED panels that can wrap around your wrist. That was especially impressive to see in action. Or so I thought until I got to see Motorola’s concept, which was much closer to a commercial product than Samsung’s wrist-worn device.
OLED Cling Band Yes, Samsung’s wrist smartwatch tech was interesting, but it was too thin for my taste. The extra height needed to partially wrap around the wrist gave it a less than ideal aspect ratio.

The first is a 17.3-inch foldable tablet/laptop that looks familiar. We saw this large-screen foldable display concept from Samsung before.

Samsung’s 17.3-inch OLED panel is simply stunning. Image source: Chris Smith, BGR Very, very thin. This display could possibly be seen on foldable laptops in the future.

Flex S display Samsung is also toying with OLED panel ideas that will let it manufacture triple-foldable devices, like the Flex S screen in the following image. When unfolded, this smartphone turns into a 12.4-inch tablet.
Triple foldable displays might feature this type of Samsung Display screen. Image source: Chris Smith, BGR Flex In & Out I mentioned the Flex In & Out earlier. This technology would let Samsung make Galaxy Z Flip and Fold devices with foldable screens that can fold in both directions.
This isn’t a regular Galaxy Z Flip phone. It folds in and out. Image source: Chris Smith, BGR The handsets would fold perfectly regardless of the direction you choose. That implies Samsung has perfected a new hinge tech to support fold-in and fold-out movements on the same device.
Samsung says the Flex In & Out will work between -20ºC (4ºF) and 60ºC (140F). The company actually hosted live bending tests at the show in extreme conditions. Robots opened and closed foldable screens in temperature-controlled environments. At -20ºC, a foldable phone can withstand up to 30,000 folds. The figure goes up to 150,000 bends at 60º.

As the name might suggest, this display tech lets Samsung fold the screen around the top edge of a foldable Flip-type phone.
