Samsung has filed a patent application, designated as US 12437686 B2, with the United States Patent and Trademark Office. This application details a groundbreaking technology aimed at repairing scratches on the inner displays of foldable smartphones. Leveraging an innovative crack detection circuit, the technology is capable of automatically identifying and rectifying scratches via a substance that mimics the behavior of 'neurons' positioned beneath the inner screen panel. The system's sensing mechanism is strategically placed around the under-display fingerprint sensor or the front camera lens.

Upon detecting a scratch, the system triggers a defensive response, employing a 'pseudo-metal pattern' to effectively seal the scratch. When combined with Ultra-Thin Glass (UTG) material and a moisture-resistant layer, this innovative technology promises to substantially improve the resilience and longevity of the inner screens of foldable smartphones, aligning with consumer expectations for durability in cutting-edge mobile devices.
