The technology is based on layers of special materials, precision hinges, cavities and seals. These components react to microcracks and can initiate the automatic repair process. When a crack is detected, the system uses metal structures to reinforce the surface. Grooves filled with sealant prevent the penetration of moisture and air.
Thanks to this technology, it is possible to place a camera and fingerprint scanner under the screen without damaging the ultra-thin glass. This improves the reliability of foldable phones by eliminating the hairline crack problem in real time. This development is intended to increase consumer confidence in the foldable form factor as more users of standard models switch to foldable devices.
This development also opens up the possibility of using under-screen ultrasonic fingerprint sensors in future Galaxy Z models. If the testing is successful, foldable devices could become a mainstream product as concerns about their durability are addressed.
