Samsung Display earlier exhibited a flexible screen technology that is still in the prototype stage. The screen called Flex In & Out can be folded 360 degrees. In other words, the device using this screen can be folded inward or outward at the same time, providing more flexibility and possibilities in design and use. Another feature of the Flex In & Out screen is the use of a new teardrop-style opening and closing hinge, which will reserve a certain amount of arc space when folding inwards to ensure that the screen will not have unsightly creases due to folding in half.
Samsung Display publicly demonstrated Flex In & Out screen technology as early as 2021, but the prototype at the time was a two-fold S-shaped design, and now it uses a single-fold design, which is closer to the Galaxy Z Fold series on sale. The technology website The Verge estimates that the Flex In & Out screen may be the first to be used in the Galaxy Z Fold5 because there were earlier rumors that this folding machine released this year will replace the current U-shaped hinge with a new drop-shaped hinge, and the screen crease will not be as noticeable as on previous models.
