Samsung Electronics started to adopt ultra-thin glass covers for its foldable AMOLEDs, instead of polyimide, as it says UTG offers higher durability. Samsung currently uses Samsung Display's UTG, and according to reports it aimed to develop its own solution in collaboration with Corning
A new report from Korea suggests that Samsung Electronics has halted this project as it realized it should better increase the efficiency of its current supply chain (i.e. Samsung Display's UTG solution) and secure lower prices. It may be that this decision is only temporarily, as it is likely that Samsung Electronics is still aiming to also increase the durability of its UTG covers and not just decrease costs.
Samsung Display's UTG cover lass is produced by Korea-based Dowoo Insys, who processes Schott's ultra thin glass for Samsung Display.
