Samsung is a pioneer in the foldable mobile sector in Europe, with the Galaxy Z Fold and the Galaxy Z Flip. Two mobiles that represent very well the possibilities of this technology, with two very different formats; one is a classic mobile that becomes a tablet when opened, and the second is halved in size when not in use.
Both of these formats have been copied time and time again by other manufacturers, in part because most use Samsung-made screens. For example, Google with the recently announced Pixel Fold, which retains the same internal flexible screen structure and the external normal screen.
Everything therefore indicates that if there is to be a revolution in the market, it will have to come from Samsung. And that’s exactly what he seems to have announced today, in a presentation that is part of SID Display Week 2023 being held these days in Los Angeles, California.
roll-up screens
The new concept presented by Samsung Display, the screen division of Samsung, consists of an incredible flexible screen capable of rolling up to a fifth of its size. In other words, it is a screen whose height does not reach more than 49 mm normally, but which if widened, it can reach 254.4mm. It is the size of a very large mobile or a small tablet, so it could be interpreted as a possible hybrid device performing the functions of both formats depending on our needs.
Samsung claims that this type of rollable screen makes it possible to transform a screen that is difficult to transport into a a more portable form factor. Although the manufacturer has yet to release models using this screen, it’s easy to see how it could be implemented in a commercial product. Although tablets and mobiles originally occupied different niches, with the new foldables that barrier has blurred; the Android operating system is also more adaptable to one use than another, and can even change in real time depending on the size of the screen.
Another interesting display-related innovation is in a new panel called the “OLED sensor”, so named because basically the whole display is one giant sensor. In this way, it is possible to unlock the device with a fingerprint by pressing anywhere on the screen, without having to press on a specific point. In addition, this screen also has health-related functions, being able to measure heart rate, blood pressure and stress level just by holding down your finger. In the demo, this data appears directly on the screen, so it could be useful for newer smartwatches or wearable health devices.
