Self-Healing Phone Screen ShieldGlass Launches: Scratches Automatically Repair Within 24 Hours
Corning releases self-healing phone screen glass ShieldGlass, containing microcapsule self-healing materials that automatically repair minor scratches within 24 hours, with approximately 70% repair rate for deeper scratches.
Corning released self-healing phone screen glass ShieldGlass on December 23. The glass surface coating embeds millions of micro-capsules, each containing liquid repair agent. When the screen is scratched, capsules rupture to release the agent that fills the scratch and cures in air.
ShieldGlass works best on minor scratches (such as key marks), which nearly disappear within 24 hours. Deeper scratches achieve approximately 70% repair. Corning's VP of materials science said ShieldGlass represents the shift from "passive protection" to "active repair" in screen protection technology.
Apple and Samsung have confirmed adoption of ShieldGlass in their 2030 flagship devices, expected to launch in fall 2030.
