Samsung Display Unveils Flex Titanium Screen for Next-Gen Foldable Phones

Samsung Display is showcasing its latest advancement in foldable screen technology with the introduction of Flex Titanium. This new innovation promises to make next-generation foldable phones thinner and more robust, while significantly reducing the visible crease that often plagues these devices.

The Flex Titanium technology integrates two key components: an ultra-thin titanium alloy film, reportedly one-third the thickness of a human hair, and a flexible titanium plate. The film provides exceptional rigidity, claimed to be 20 times stiffer than previous polymer films, supporting the OLED panel from beneath. The titanium plate underneath further reinforces the panel, ensuring a flatter and more uniform surface when the device is folded or unfolded, even after hundreds of thousands of cycles.

Through the application of micro-patterned holes on the folding part of the titanium plate, we have achieved both flexibility and strong durability.

Kyung-Jin Yoo, Corporate EVP and Head of Mobile Display Product Development Team at Samsung Display, highlighted the engineering feat. "Through the application of micro-patterned holes on the folding part of the titanium plate, we have achieved both flexibility and strong durability," Yoo stated. He added that by combining this with a high-resolution display architecture and new organic materials for power efficiency, Samsung aims to strengthen the competitiveness of its future foldable Galaxy devices.

The choice of titanium is driven by its high strength-to-weight ratio, ideal for portable electronics. However, integrating this strong material into a thin, flexible screen structure presented significant engineering challenges. Samsung is also hinting at new form factors at its upcoming Galaxy Unpacked event in London, themed "A New Shape Unfolds," fueling speculation about a wider, book-style foldable device.
