The new technology solves two major problems in foldable phones: the appearance of a crease line in the middle of the screen and the devices’ weak resistance to shocks. Samsung says that “Flex Titanium” provides more durable screens while reducing the visibility of the folding effect, while maintaining screen flexibility and display quality.
The technology relies on integrating two layers of titanium into the screen structure instead of one layer. The first layer consists of a membrane made of titanium alloy that is placed directly under the OLED panel, and provides mechanical rigidity that is approximately 20 times greater than the previously used polymeric film.
Despite the rigidity of the material, the thickness of the film does not exceed a third of the thickness of a human hair, thanks to the “micro-rolling” process that Samsung developed for this purpose.
The second layer is a flexible titanium plate located below the first membrane, and it works to support the screen from the bottom when the device is fully opened. Samsung relies on a precise treatment that contains microscopic holes in the folding area, with the aim of reducing air gaps between the screen components and adhesive materials, and enhancing the cohesion of the two layers.
The benefits of the technology include reducing the crease line in the middle of the screen, increasing the device’s resistance to daily shocks without increasing the thickness, in addition to maintaining the flexibility of the folding despite the use of a solid metal material such as titanium.
The development was also accompanied by updates to the display resolution structure and the use of new generation organic materials, with the aim of improving energy efficiency without affecting image quality.
Samsung is preparing to display additional details about the technology during the “Galaxy Unpacked” event, including prices and final specifications for the first device to officially carry this technology. (Erm News)
