When it comes to the foldable smartphones, they have a persistent weak spot having fragile display areas around the camera and sensors.
Now this will also get resolved owing to a new Samsung patent which reveals a system using internal sensing wires and metal patterns to actively detect and self-heal micro-cracks on the delicate foldable screen.
Struggle Is Over For Samsung Foldable Smartphones
It can not be denied that for years, foldable phone manufacturers have struggled with a major engineering roadblock which is how to securely place components like cameras and fingerprint sensors beneath the flexible display.
For doing so, they need to cut a hole for these sensors which in turn creates a structural weak point in the layered screen.
Which further makes it prone to microscopic cracks and moisture damage.
Due to this hidden weakness, the devices like the Galaxy Z series still rely on side-mounted fingerprint sensors.
In this regards, Samsung recently published it’s patent whichreveals the company’s ambitious answer to this issue in thegorm of a built-in defense and “self-repair” system for cameras and fingerprint sensors for foldable devices—like the latest Galaxy Z Fold 7 and Z Flip 7.
Basically, this technology fundamentally changes how the screen protects itself, moving beyond passive durability and toward active self-monitoring.
New Technology Provides Self-healing Display Protecting Sensors
Basically this patented system involves embedding microscopic wires and sensors—a “sensing loop”—directly around the display cutouts.
When it comes to these wires, they constantly act as the screen’s immune system which helps in instantly detecting even the smallest stress or crack in the underlying layers.
After sensing a potential threat this system activates a unique reinforcement process by triggering “dummy metal patterns” that automatically seal and strengthen the damaged section.
It can be simply be considered as the screen immediately putting a tiny, invisible patch over the flaw, stopping the crack from spreading further.
Moving ahead, this design includes specialized grooves and sealants to actively shield the OLED layers from oxygen and moisture intrusion.
Here three-part defense system works which includes – sensing, sealing, and reinforcing, solving the long-standing durability problem.
On top of this, Samsung clears the final hurdle for implementing truly reliable, in-display fingerprint sensors on future Galaxy Z Fold and Flip models by making the area around the camera and sensors as secure as the rest of the display.
Please note here that this is a patent, so its implementation in commercial products isn’t set in stone.
So far, Samsung is at least actively researching the topic as per the filing and hopefully, the company will find a reliable and cost-effective implementation, as the technology would make foldable phones significantly tougher for everyday use.
