Samsung is using titanium to finally tackle the foldable crease problem with the Galaxy Z Fold 8

Q: Might Samsung Display’s Flex Titanium become available to other manufacturers, such as for a rumored foldable iPhone?

The primary article says Flex Titanium is confirmed for the Galaxy Z Fold 8 and that the technology could eventually make its way to other devices, naming a likely candidate as Apple’s long-rumored foldable iPhone because Samsung Display reportedly secured a three-year exclusive deal to supply its displays. Related coverage (“Samsung Display producing even more foldable OLED panels, ready for Apple’s foldable iPhones”) also notes Samsung Display is increasing production capacity for foldable panels for Apple, suggesting availability to other manufacturers is possible.

Flex Titanium combines a titanium-alloy film 20 times stiffer than polymer alternatives with a micro-patterned plate that eliminates air gaps at the fold.

TL;DR: Samsung's "Flex Titanium" uses a titanium-alloy film beneath the OLED that is 20× stiffer than prior polymer films and under 30% of a hair's thickness, plus a micro-patterned titanium plate with holes to remove air gaps and stay flexible, reducing fold crease visibility on the Galaxy Z Fold 8 and Z Fold 8 Ultra.

Samsung's Galaxy Z Fold 8 series will use a new foldable display technology that will finally fix the crease visibility. The company is calling it "Flex Titanium", a new display technology for its next generation of foldable devices, ahead of Galaxy Unpacked on July 22. Samsung says the tech is the culmination of everything that the company has learned over seven generations of foldables.

Flex Titanium is built around two titanium-based components to improve strength, flexibility, and slimness. The first component is a titanium-alloy film that sits beneath the OLED panel. Samsung says it offers 20 times greater mechanical stiffness than the polymer films used in previous designs while measuring less than 30% the thickness of a human hair.

The second component is a titanium plate positioned below the film, which eliminates air gaps between the display module and its adhesive using what Samsung describes as advanced hole-processing technology. Micro-patterned holes in the plate's folding section allow it to remain sufficiently flexible for repeated folding while providing more stable support when the device is open.

Samsung is careful with its language here, promising reduced crease visibility rather than claiming the crease is gone entirely. Foldable makers have generally been cautious with these claims to avoid overpromising. Oppo, for example, markets the Find N6 with a zero-feel crease, yet even reviewers who describe it as one of the least visible creases on any foldable stop short of calling it invisible.

Question #1

What is Flex Titanium and how does it differ from the polymer films used in previous Galaxy Z Fold displays?

Flex Titanium is a new foldable-display technology Samsung will use in the Galaxy Z Fold 8 that combines a titanium-alloy film beneath the OLED panel with a micro-patterned titanium plate below that to eliminate air gaps at the fold. The titanium-alloy film offers 20 times greater mechanical stiffness than the polymer films used in previous designs while measuring less than 30 percent the thickness of a human hair, and the micro-patterned titanium plate provides flexible support at the hinge and reduces air gaps for a flatter open display.

Answered

Question #2

What role does the micro-patterned titanium plate play in reducing crease visibility on the Fold 8?

The micro-patterned titanium plate sits below the film and eliminates air gaps between the display module and its adhesive by using advanced hole-processing technology. Its micro-patterned holes let the plate remain flexible enough for repeated folding while providing more stable support when the device is open, which reduces crease visibility.

Answered

Question #3

Could Flex Titanium affect durability or repeated folding reliability compared to prior Fold generations?

Yes. The article says Flex Titanium uses a titanium-alloy film that is 20 times stiffer than the polymer films used previously and a micro-patterned titanium plate that eliminates air gaps while allowing the folding section to remain sufficiently flexible for repeated folding. Samsung presents the tech as improving strength, flexibility, and slimness compared with prior designs, which implies better durability and folding reliability.

That said, previous leaks of what is believed to be the Galaxy Z Fold 8 Ultra show a display crease that appears almost impossible to spot. Flex Titanium is already confirmed for both the Galaxy Z Fold 8 and Z Fold 8 Ultra, and the technology could eventually make its way to other devices as well. One likely candidate is Apple's long-rumoured foldable iPhone, with Samsung Display reportedly securing a three-year exclusive deal to supply its displays.
