Samsung's got a nice little ecosystem of foldable smartphones going, with the Galaxy Z Fold 2 and the original Fold positioned as flagships, and the vertically-folding Galaxy Z Flip being the more affordable option. But the company's plans for foldables don't stop there.In a new YouTube video, Samsung Display shows off new display technologies, and that includes several foldables as well as several other cool gadgets.Perhaps the most interesting among these is a dual-folding phone or S-Foldable as Samsung calls it which folds in two places to turn from a tablet-sized device to something very pocketable. We get a good look of the device from all sides, and at one point, we see its dual hinges working their magic.The video also gives a glimpse of a rollable phone (Samsung calls it "slidable"; I guess that works, too), the right side of which can easily be expanded for more screen estate.SEE ALSO: Samsung's Galaxy Book Pro is a not-so-subtle shot at the MacBook ProWe also get to see a dual-display laptop similar to Lenovo's Yoga Book with the lower part dynamically changing from display to game controller to keyboard.And at one point, Samsung shows a laptop with nearly non-existent bezels, which is achieved by using an invisible, under-panel camera as the webcam.No bezels.Image: samsungThese are all just concepts, and there's no indication that they'll become actual products soon, or ever. However, the technologies to create all of these are actually here right now, so I wouldn't be too surprised if some of these products show up in real life fairly soon.
