Manufacturers have been working on foldable smartphones for years, continuously advancing the technology. Apple is also working on its first iPhone Fold, focusing on new approaches to the display.
Foldable smartphones offer large displays with minimal space requirements. However, opening and closing them exerts additional stress on the internal screen. These forces directly impact the material and can wear it down over time. This is where Apple aims to improve the design of its first foldable iPhone.
Leak Shows New Approaches in Display Technology
The technical information comes from the well-known leaker Digital Chat Station. According to their reports, Apple is further developing the previously known UTG technology. UTG stands for Ultra Thin Glass and is already used in foldable smartphones. Apple is apparently working on a more stable version for the iPhone Fold’s display, combining multiple layers of glass.
These layers are intended to better distribute stress and protect the sensitive display. Additionally, Ultra Flexible Glass, or UFG, is mentioned. This material is considered particularly flexible and durable.
Two-Layer Structure to Ease Display Stress
An important component of the new solution is a two-layer glass structure. Two thin glass layers are placed on the outside, with the display in between. This design evenly distributes forces during folding and protects the screen. It also prevents direct contact with the hinge, further reducing stress. The visible crease in the middle, typical of foldable smartphones, might be less noticeable in the iPhone Fold.

Changes to the OLED Display Structure
In addition to the glass structure, Apple reportedly plans adjustments to the display itself. This involves the OLED panel’s construction. The technology Color Filter on Encapsulation, or CoE, is set to be used. Here, a color filter is applied directly to the display’s protective layer, eliminating the need for an additional film. This makes the displays overall thinner and lighter, requiring less energy.

Focus on Stability and Everyday Usability
The release date for the iPhone Fold remains uncertain. Recent rumors suggest the device might not be unveiled until December. Current indications show that Apple is prioritizing stability. Durability is a key factor, which is why the company has not yet released a foldable iPhone. If the new design is implemented, the device could be more robust than current foldable smartphones, addressing a known weakness in this category.
