VitaGlass Self-Healing Screen Coating Passes Mass-Production Validation: Minor Scratches Disappear Within 24 Hours
A self-healing glass coating called VitaGlass, jointly developed by the University of Tokyo and AGC, has passed mass-production validation. Made of microcapsules, the coating releases repair fluid when the screen is scratched, and the scratch fully disappears within 24 hours. AGC plans to supply samples to Samsung and Apple in Q3 2026.
VitaGlass Self-Healing Screen Coating Passes Mass-Production Validation: Minor Scratches Disappear Within 24 Hours
VitaGlass, a smart glass coating jointly developed by the University of Tokyo and AGC, has passed mass-production validation. The coating is made of repair microcapsules just 3 micrometers in diameter, distributed evenly beneath the glass surface. When the screen sustains a minor scratch, the capsules in the damaged area rupture and release a silane-based repair liquid; the liquid flows into the scratch and cures at room temperature, making the scratch fully disappear within 24 hours.
Third-party testing firm SGS ran a standard abrasion test on VitaGlass with 2,000 steel-wool passes. The coating fully repaired scratches up to 8 micrometers deep, and reduced the visibility of deeper damage by roughly 70 percent — well beyond any self-healing product previously on the market, including the solutions used by LG and Motorola on their foldable phones.
AGC plans to ship VitaGlass coating samples to Samsung Display and BOE in Q3 2026, initially targeting premium foldable devices. Mass-production cost is currently around $6.80 per display; AGC said costs could fall below $3 within two years as capacity ramps, in line with conventional tempered-glass coatings.
