Huawei and OPPO’s latest foldables feature polysilazane (PSZ)-coated ultra-thin glass (UTG), tripling scratch resistance versus traditional polymer screens. German glassmaker Schott AG partnered with Asian materials firms to apply nanometer-thick PSZ resin onto 0.03mm glass, forming a ceramic-like layer after curing. This innovation meets military-grade impact standards and survives 10,000 daily folds without degradation. Production costs dropped 30%, accelerating foldable display adoption globally.
