Samsung Galaxy Z Fold 8: Achieving Crease Control Mastery with Dual-UTG Display Technology

As the anticipation builds for Apple's inaugural foldable iPhone, Samsung appears poised to leap ahead in the competitive foldable market. Early insights suggest that Samsung is preparing a significant display innovation for the upcoming Galaxy Z Fold 8, potentially featuring a dual Ultra-Thin Glass (UTG) setup engineered to virtually eliminate the screen crease.

According to recent reports, Samsung is targeting a substantial improvement in crease management for the Galaxy Z Fold 8 by implementing this dual-UTG technology. This advancement is projected to reduce the visibility of the screen crease by an impressive 20 percent compared to its predecessor, the Galaxy Z Fold 7. This generational leap in display refinement certainly suggests that the competitive pressure from rivals is driving meaningful innovation in the foldable segment.

An industry source detailed the engineering breakthrough, stating, “It appears the function was improved by forming numerous micro-holes in the backplate through laser drilling to disperse stress.” This method focuses on mitigating the physical strain that causes the crease, offering a smoother viewing experience.

Samsung Display showcased this advanced foldable screen at CES 2026, providing side-by-side comparisons that highlighted marked improvements in crease reduction, color accuracy, and overall panel quality. This development is particularly noteworthy as Samsung Display is also a key supplier for Apple's upcoming foldable iPhone, meaning this technology is being refined to meet high, cross-brand standards.

The dual-UTG solution builds upon the Ultra-Thin Glass technology Samsung has utilized for years in its Galaxy Z lineup. While Apple is expected to be a primary beneficiary of Samsung Display's advancements, the Samsung Mobile eXperience (MX) Division is also set to integrate this technology. Minor differences in production might still give Samsung's internal mobile division a slight advantage in initial rollout or specific feature implementations.

Here are the key takeaways regarding the expected Galaxy Z Fold 8 display:

  • ✨ The Galaxy Z Fold 8 is anticipated to feature a new dual-UTG foldable OLED display.
  • ✨ This technology aims to reduce the visible screen crease by approximately 20% compared to the Galaxy Z Fold 7.
  • ✨ Stress dispersion is achieved by creating micro-holes in the display's backplate via precise laser drilling.
  • ✨ This innovation addresses the primary visual drawback of current generations of foldable smartphones.

The focus on such a critical refinement suggests Samsung is determined to maintain its leadership position in the premium foldable space, especially against imminent competition. 

How does the dual-UTG technology work to reduce the crease?

The dual-UTG system incorporates a technique where numerous micro-holes are precisely drilled into the backplate of the display using a laser. This process effectively disperses the physical stress concentrated along the fold line, resulting in a flatter surface and significantly less visible creasing when the device is opened.

Will this new display only benefit the Galaxy Z Fold 8?

While the Galaxy Z Fold 8 is expected to be a primary recipient of this improved screen, the technology is being developed by Samsung Display, which also supplies panels to other major manufacturers, including Apple. Therefore, this advancement sets a new benchmark for foldable displays across the industry, though Samsung’s own mobile division will likely benefit first or have specific manufacturing advantages.

What is the expected percentage reduction in crease visibility?

Industry reports estimate that the implementation of the dual-UTG solution in the Galaxy Z Fold 8 will result in the crease being approximately 20 percent less visible when compared directly to the crease found on the current Galaxy Z Fold 7 model.

When might consumers see this technology implemented in Samsung devices?

Given that the Galaxy Z Fold 8 is the device directly linked to this new display technology, it is expected to debut with the next generation of Samsung’s flagship foldable, likely later in the year following the typical launch schedule for the Z Fold series.

🔎 This focus on minimizing the visual crease marks a significant step forward in the evolution of foldable smartphones. By addressing one of the most persistent aesthetic and tactile complaints from users, Samsung is ensuring its next foldable iteration offers a more premium and seamless user experience, solidifying its competitive edge in this rapidly developing hardware category.
