[Edaily Reporter Shin Yeong-bin ] SamsungElectronics(005930)has unveiled next-generation display technology that addresses screen creasing and durability—long-standing challenges for foldable phones. The key innovation lies in using a titanium alloy instead of plastic film, making the screen thinner and sturdier while maintaining the flexibility needed for repeated folding and unfolding.

On the 15th, SamsungElectronics unveiled its “Flex Titanium” display technology, which will be used in its next-generation Galaxy foldable devices. The company explained that it redesigned the display structure and materials based on the experience it has accumulated over seven generations of foldable product development.

Flex Titanium features a dual-layer structure combining a “titanium alloy film” placed beneath the OLED panel and a “titanium plate” that supports it. By replacing the plastic-based polymer film used in previous foldable displays with a high-elasticity, high-rigidity titanium alloy film, the company has enhanced the screen’s structural stability.

The titanium alloy film is approximately 20 times stiffer than conventional polymer films. It suppresses deformation that occurs as the display folds and unfolds, thereby improving durability and helping to reduce creases that form in the center of the screen.

The thickness has also been minimized. SamsungElectronics utilized an ultra-precision rolling process to make the titanium alloy film about one-third the thickness of a typical human hair. The company explains that this contributes to the slim design of next-generation foldable devices by reducing the issue of increased display thickness despite the use of a high-rigidity metal.

A titanium plate that supports the display is positioned beneath the titanium alloy film. This component provides stable support for the screen when the device is unfolded and helps the display bend smoothly when folded.

Samsung has also improved the micro-hole machining technology applied to the folding area. By reducing the size of the holes drilled into the titanium plate, the company has made the adhesive structure more robust while maintaining flexibility at the folding point. The company explained that this enhances structural stability when the screen is unfolded and reduces creasing.

Titanium is a material known for its high durability and reliability, used even in extreme environments such as the aerospace industry. However, its high elasticity and rigidity made it difficult to apply to foldable displays, which must be extremely thin and folded repeatedly. Samsung emphasized that it overcame these technical constraints by combining material processing with display structural design.

Image quality and power efficiency have also been improved. The Flex Titanium display features a high-resolution design and next-generation organic materials. Samsung stated that it has enhanced power efficiency by reducing display power consumption while simultaneously improving screen quality.

Moon Sung-hoon, Vice President in charge of Hardware at SamsungElectronics’ MX Business Division, said, “Based on our display technology expertise accumulated over many years, the newly launched next-generation Galaxy Foldable will deliver an unprecedented viewing experience.”

Yoo Kyung-jin, Vice President and Head of Product Development at Samsung Display, explained, “We secured both flexibility and durability by applying micro-perforation to the folding section of the titanium plate,” adding, “We also maximized power efficiency through high-resolution design and the use of new organic materials.”

Flex Titanium technology will be applied for the first time to the next-generation Galaxy Foldable devices. Specific models and product specifications are scheduled to be unveiled at the “Galaxy Unpacked” event to be held in London, UK, on the 22nd.

Meanwhile, SamsungElectronics has led the flexible display and foldable smartphone markets since 2007, when it became the first in the world to begin mass-producing AMOLED displays.
