Samsung Recently announced the industry’s first folding screen with ultra-thin flexible glass UTG (Ultra Thin Glass) cover plate mass production and commercial. The technique was questioned by Jerry Rig Everything’s durability test, and Samsung later said it was easy to scratch the glass surface by using the same protective film as the Galaxy Fold.
Today’s disclosure of an internal Samsung document shows the differences in screen technology between the Galaxy Fold and the Galaxy Z Flip, with a focus of concern being the special shock absorber layer under the UTG layer to help improve device reliability by mitigating the impact. The “Winner” on the right is the in-house development code for Samsung’s Galaxy Fold, while the “Bloom” on the left is the development code for the Galaxy Z Flip.
This shock absorber layer is very important because the glass is a brittle substance and is very easy to damage when under pressure, especially thin enough to bend. In addition, the internal report also indicates that the shock absorber can reduce the effects of cracks and bubbles. UtG used in Z Flip replaces the polyimide layer used in Galaxy Fold.
