Samsung patents “self-healing” screen technology for next-generation foldable phones

Samsung has reportedly filed a new patent for a "self-healing" display technology that can automatically repair micro-cracks on foldable phone screens. It's a significant step in efforts to improve the durability of next-generation foldable devices. So, what should you know about it?

A tech that focuses on the most vulnerable part

For your information, this technology focuses on the most vulnerable parts of the display, such as the area around the camera hole and sensor. Samsung developed a system based on a sensing loop, which is a network of micro-wires that detect pressure or fine cracks.

Additionally, when detected, the system will activate a dummy metal pattern to reinforce the area and prevent damage from spreading. The patented design also features micro-grooves and a special sealant that prevents oxygen and moisture from entering the OLED structure. These two sources are factors that can affect the lifespan of the display.

In addition to improving physical durability, this technology could also enable the integration of an in-display fingerprint sensor on foldable phones. However, this patent has yet to be validated for use in a real product. As with most innovations, implementation will depend on cost and production feasibility.
