Samsung’s next foldable phone could fix its display when cracked

Samsung may be ready to solve one of the biggest pain points in foldable phones, their fragility. A newly spotted patent hints at a self-healing display designed to repair tiny cracks and prevent long-term damage. Filed under Samsung’s growing list of foldable innovations, the document outlines a screen structure that can detect stress points and reinforce itself before the damage spreads.

The patent, unearthed by leak sources Xeaks7 and Summarize Meeting, details a sensing loop placed around sensitive areas like camera holes or fingerprint readers. These micro-loops detect small fractures in real time, while thin wires embedded across display layers monitor the screen’s health. To add another layer of protection, Samsung uses microscopic grooves and sealants to block oxygen and moisture, two major culprits in display degradation.

Towards smarter, stronger foldables

The design goes beyond just detection. The system reportedly employs dummy metal patterns that activate when cracks appear, reinforcing the affected spot and preventing further damage. The idea is that the screen wouldn’t just withstand wear and tear; it could literally heal itself!

This development could also be the key to finally enabling in-display fingerprint sensors on foldables, something Samsung has struggled with since the first Galaxy Fold. If realised, it would mark a major leap in both usability and durability, merging premium features with longevity.

Samsung’s foldable lineup, led by the Galaxy Z Fold and Z Flip, already dominates the market. But the company’s next chapter might not just be about new form factors; it could be about form factors that fix themselves.

With rumours of a tri-fold Galaxy Z TriFold launching at the end of October, Samsung’s foldable story seems far from finished. It’s just getting smarter.
