Galaxy Z Fold 8, Samsung will use an additional UTG layer

With the highly anticipated debut of the first iPhone Fold expected this very year, competition is intensifying rapidly, pushing the industry to innovate more aggressively.

Samsung seems determined to solve one of the most persistent and visible issues of this category of devices: the central crease of the display.

According to the latest rumors, the South Korean giant is working on implementing a new dual-layer Ultra Thin Glass (UTG) structure for Galaxy Z Fold 8, with the aim of making the inner screen more uniform than ever.

Samsung Galaxy Z Fold 8, a New Display Architecture

The main novelty lies in a structural modification of the foldable OLED panel. According to a recent report from DealSite, Samsung Display has developed a technology that calls for applying Ultra Thin Glass not only on the outer surface layer, as in previous generations, but also on the bottom of the panel.

This “sandwich” configuration, with UTG applied on both sides, has been designed to improve structural rigidity and the planarity of the screen when it is open.

Early results look promising: adopting this double glass armor should reduce the visibility of the crease by about 20% compared to the current model, the Galaxy Z Fold 7.

Samsung Display offered a preview of this technology at CES 2026, held a few weeks ago, where it showcased an OLED panel characterized by an optimized laminated structure and by better light dispersion, factors that help further mask the central bulge to sight and touch.

Divergent Strategies: Samsung vs Apple

Although Samsung Display provides the base technology, it seems that Samsung Electronics and Apple will adopt differing engineering approaches for their respective devices slated for release this year.

Rumors suggest that Apple’s foldable could use a glass substrate for managing the bend, while the Galaxy Z Fold 8 would rely on a laser-cut metal backing plate.

This metal plate features laser-etched micro-perforations, a refined technical solution that helps distribute mechanical stress more evenly during the closing and opening movement.

The combination of the double UTG layer and the perforated metal support aims to strengthen the folding structure, minimizing material deformation at the bend and ensuring higher longevity.

If reports on the Galaxy Z Fold 8 prove accurate, this year we may finally witness the removal of the last true psychological and aesthetic barrier for users.

Eliminating, or making the central crease nearly imperceptible, would mean offering a no-compromise visual experience, finally equating the usability of foldables with that of traditional tablets and smartphones.

With Apple ready to enter the arena, Samsung is clearly sharpening its weapons to maintain its technological lead.
