According to the reports, Apple is developing a foldable iPhone internally, and it is estimated that it will only be officially released after a key breakthrough in related technologies. And Apple’s upcoming foldable iPhone may solve a pain point of the existing Galaxy Z Fold/Flip series, providing better protection for foldable devices and preventing cracks.
Citing a Patently Apple report, Apple recently received a patent for “Hybrid coverlay/window structure for flexible display” (hybrid coverlay/window structure for flexible screens), and the patent application number is 20210096595. The patent filed in mid-October 2020 is a continuation of the previous patent and describes a technology that can prevent potential screen damage in foldable devices.
The embodiment describes the structure of the display module and the protective cover layer. In particular, the embodiments describe a protective cover layer structure that can be implemented in a bendable, flexible, conformable, and foldable display module, especially in combination with a bendable, flexible, conformable, and foldable display module. Display panel. Various embodiments are described in which a hard coat layer is applied to a transparent support substrate to form a protective cover layer structure.

The hard coat layer can be characterized as having a lower modulus of elasticity, higher elongation at break, and optionally lower hardness than the transparent support substrate. In one aspect, such a hybrid structure can prevent cracks from forming in the transparent support substrate. In another aspect, such a hybrid structure can move the neutral plane of the protective cover layer so that the surface of the transparent support substrate sees lower strain when it is bent.
The patent contains clear images that show devices that can fold in and out, as well as gadgets that can be like Samsung’s Galaxy Z Fold and Galaxy Z Flip devices. The patented illustrations basically cover the existing folding methods, so it is not clear what kind of design the first foldable device will adopt.
