The fold mark in the middle of the screen, which is one of the biggest problems of foldable smartphones, continues to be one of the main issues that manufacturers work on. Samsung is working on a new technology to solve this problem and increase device durability.

This new solution developed by the company is similar to the approach Apple planned for the iPhone Fold model. This technology aims to reduce the visibility of fold marks on the screen and extend the physical life of the device.

Thicker Ultra Thin Glass (UTG) Technology

According to the information shared by ZDNet Korea, Samsung plans to use a thicker Ultra Thin Glass (UTG) in the Wide Fold model of its new generation foldable device. The thickness of this new glass will be 60μm.

Compared to the 45μm thick glass used in the Galaxy Z Fold 8 model, the new technology offers a 30 percent thicker structure. Although Samsung is a pioneer in foldable display technologies, it has until now preferred thinner glass frames to reduce the risk of panel breakage.

Although the use of thinner glass reduces the possibility of damaging the panel when the device is folded completely, it causes the screen mark to be more obvious. In addition, this structure limits the device’s resistance to sharp objects.

Competition and Engineering Challenges

Apple’s aim to present the screen surface with as smooth and clean aesthetics as possible with the iPhone Fold forces other manufacturers in the sector to take similar steps. Samsung aims to get ahead of the competition by adopting this new design approach that minimizes screen print.

The use of thicker UTG brings with it some engineering difficulties and cost increases. In particular, ensuring that the device survives 200 thousand folds requires a significant research and development process.

This technological investment by Samsung aims to raise the standards in the foldable phone market. Do you think a thicker screen glass can improve the lifespan and experience of foldable phones as much as expected?
