Analyst Suggests Apple’s First Foldable iPhone Must Have Chemically Strengthened Thicker Front Glass to Eliminate Creasing

Apple’s ambitious endeavor to launch mass production of a foldable iPhone appears to be gaining momentum. Recent reports indicate that the tech giant is actively shortlisting potential suppliers for the essential components needed to kickstart this innovative project. The anticipated release date for this groundbreaking device is set for the latter half of 2026. A key feature of this foldable iPhone is expected to be a seamless display, free from the visible crease that has plagued competitors in the market. This challenge has persisted despite rival manufacturers having years of experience in foldable smartphone production.

Advancing Technology to Eradicate the Crease

To achieve a crease-free design, insights from display analysts suggest that Apple will need to transition from plastic screens to thicker glass. Ross Young, founder and CEO of Display Supply Chain Consultants, outlined the necessity of this change on social media platform X. Young underscored that a chemically treated glass could endure numerous folds while minimizing crease formation over time. Furthermore, he recommended reducing the thickness of the seam area, which could further enhance the device’s durability and aesthetic appeal.

However, a significant hurdle remains: securing a supplier capable of mass-producing this thicker front glass. Reports indicate that Samsung is slated to provide OLED panels for both the inner and outer displays of the foldable iPhone. Apple is reportedly considering a “book-style”design similar to that of the Galaxy Z Fold 6. Samsung has integrated Ultra Thin Glass (UTG) technology in its devices, which allows for extensive folding but often results in that undesirable crease.

Whether they can eliminate the plastic hard coat which scratches too easily would be important. Going to thicker glass that can be chemically strengthened and selectively thinning the seam area would be good.https://t.co/NzKl3wgxYY

There is speculation that Samsung may establish a dedicated facility to manufacture the thicker front glass. While some may question Samsung’s investment in production for a single client, it’s worth noting the company has previously set up similar lines to manufacture tandem OLED screens for Apple’s M4 iPad Pro series. Initially, Samsung was hesitant to undertake such a project, citing financial viability concerns unless Apple placed a substantial order. However, a mutually beneficial agreement seems plausible, as the development of a thicker front glass is crucial for Apple’s goal of eliminating the crease in its foldable iPhone.
