Samsung is testing a new display material that could make foldable phones easier to use and more durable. The company is researching Center-etched Thin Glass (CTG) to replace or augment the current Ultra-thin Glass (UTG) panels. This shift matters because it directly targets the visible crease and fragility issues that have plagued early foldable designs. Buyers who prioritize screen longevity and a flatter viewing experience should watch for these hardware updates.
Center-etched Thin Glass aims to improve durability and foldability
The technology targets Samsung's upcoming Galaxy Z Fold 9 and potentially the Galaxy Z Flip 9 series. Samsung Display is currently working on a hybrid solution for its UTG implementation while developing CTG. The new glass technique thins only the central part of the display panel. This specific etching aims to reduce crease visibility and allow for easier folding mechanics.
- Display Technology: CTG (Center-etched Thin Glass)
- Current Technology: UTG (Ultra-thin Glass)
- Target Release Year: 2027
Current foldable devices rely on UTG, which Samsung is reportedly refining with hybrid approaches. The CTG technology aims to provide a flatter panel appearance compared to existing glass solutions. Full clarity on which specific models will receive this upgrade is expected in the fourth quarter of the current year. We touched on Samsung Galaxy Z Fold 8 Ultra in our earlier Samsung coverage.
Reports suggest CTG could be present in the Galaxy Z Fold 9 series of foldables coming out next year. However, the timeline creates some ambiguity as sources also mention 2027 for next-generation foldable tech. The technology may only apply to some models within the series rather than the entire lineup. Samsung has not confirmed final pricing or availability for these devices.
