With just around a week left till Samsung formally unveils its latest lineup of foldables, the South Korean tech giant has now removed the wraps from one of the biggest mysteries of the upcoming launch galore: how the Galaxy Z Fold 8 and Fold 8 Ultra will keep the dreaded display crease at bay.
Samsung's Titanium Flex involves an extremely thin titanium-alloy film that sits just beneath the OLED panel, and bolstered by an underlying titanium plate
Samsung's Titanium Flex is an inventive solution to the display crease problem that has plagued nearly every foldable till now, and involves 2 distinct layers of titanium, where the first sits just beneath the OLED panel, and is made of a titanium-alloy film that is around 30 percent the width of a human hair but offers 20x the stiffness of a generic plastic film used in past models, while a titanium plate sits beneath the display module, and gives steadier support.
According to Samsung, the titanium plate uses micro-patterned holes that eliminate "air gaps between the module and adhesive for more stable support when unfolded, while retaining the flexibility needed for repeated folding."
Apparently, this titanium combo substantially increases the display's resistance to developing micro-cracks, which are the root cause of the display crease that then forms over time.
Interestingly, Samsung is likely to abandon a titanium backplate for the Galaxy Z Fold 8 and its Ultra counterpart, relying instead on one made from a carbon fiber-reinforced plastic. This suggests that Samsung's use of the metal is moving to internal components instead of external ones.
