Samsung Develops New Foldable Display Tech to Reduce Creases

WireByte Staff · August 4, 2026

Samsung Display is reportedly developing a new ultra-thin glass technology called CTG, which could make creases on foldable phones less noticeable. The technology, still under development, may arrive as early as the Galaxy Z Fold 9 series next year. This comes after Samsung's latest foldables set new pre-order records. The impact on the market and consumer demand remains to be seen.

Key points

  • Samsung Display is developing CTG (Center Etched Thin Glass), a new ultra-thin glass technology for foldables.
  • The technology thins only the section that bends when the phone is folded, keeping the rest of the glass stronger.
  • CTG may arrive as early as the Galaxy Z Fold 9 series next year, although adoption has not been confirmed.
  • Samsung's latest foldables set new pre-order records, indicating strong consumer demand.
  • Industry experts say this technology could have a meaningful impact on the foldable phone market.

Samsung Display, a leading manufacturer of display panels, is reportedly developing a new ultra-thin glass technology called CTG (Center Etched Thin Glass). This technology aims to reduce the visibility of creases on foldable phones, a common issue with current foldable devices.

According to industry sources, CTG works by thinning only the section of the glass that bends when the phone is folded, while keeping the rest of the glass stronger. This design allows the display to remain rigid and durable when the device is open.

The development of CTG comes after Samsung's latest foldables, the Galaxy Z Fold 8 and Z Flip 8, set new pre-order records. This indicates strong consumer demand for foldable phones, and Samsung is likely looking to capitalize on this trend.

While the exact impact of CTG on the market and consumer demand remains to be seen, industry experts say this technology could have a meaningful impact on the foldable phone market. If successful, CTG could make foldable phones more appealing to consumers, potentially leading to increased adoption and market growth.

However, it's worth noting that CTG is still under development and no adoption has been confirmed. Samsung Display is reportedly aiming to have CTG ready for commercial devices as early as next year, but this timeline is subject to change.
