In studying the types of foldable or curved displays, Apple also now suggests that the iPhone display itself can & quot; cure & quot; the inevitable wear and tear. Now, a newly disclosed Apple patent application proposes a way to minimize damage and do something when it happens. Apple’s patent, called electronic device with flexible display cover, proposes a display screen with a mixture of rigid and flexible areas, and then uses what Apple calls self-healing;. Perhaps this self-healing part is the most interesting part of the patent application. Unfortunately, although 147 of the more than 11000 words in the application form mentioned it, there are many details about what self-healing will do, but few details about how it can be realized. < / P > < p > Apple said in its patent: & quot; electronic devices can have a hinge that allows the device to bend around the bending axis, and a display can span the bending axis. In order to facilitate bending around the bending axis without damage, the display screen may include a display cover layer with a flexible portion. &Apple suggests that while the display can stretch across the entire device, it may consist of three elements. Two of them will be regular fixed screens, while the third will be flexible parts that connect these screens together. < p > < p > Apple said that during the operation of electronic devices, the display cover of electronic devices may be scratched or dented, and in order to improve the aesthetics of electronic devices, it may want to minimize the existence of scratches and dents. To help reduce the number of dents, scratches, or other defects in the display overlay, the display overlay may include a layer of self-healing material. Apple proposes that the flexible layer itself can contain a layer of elastomer, which is a self-healing element. The elastomer is stretchable, but it can be restored to its original shape. An analogy is a memory foam in some mattresses. Usually, this ability to return to its previous shape is triggered by heat, such as the body temperature of a person sleeping on a mattress. < p > < p > Apple said that self healing may occur in the self-healing material layer without prompting (for example, when the self-healing coating has dents, the coating material can fill the dents even without external intervention). In addition, self-healing can be initiated or accelerated by externally applied thermal, optical, electric current or other types of external stimuli, such as when electronic devices are used Heat is generated during standby charging. < / P > < p > the patent application does attempt to cover all possible scenarios, so it carefully States, for example, that the technology can be used for everything from & quot; computing devices, such as laptops & quot; to mobile phones, and even & quot; smaller devices, such as watch devices, pendant devices, wearable devices, or other types of micro devices;. It also said that the display can be such a configuration consisting of two rigid elements and a flexible element in the middle, but it can also be a single display. However, in all the descriptions, it is believed that the display screen will be composed of multiple layers. It may have an outermost layer formed by transparent glass, transparent plastic, sapphire or other transparent materials as the protective layer for thin-film transistor circuits and other display structures. Some layers will be used as the actual display screen, while others will be used to protect the screen, especially when it is bent The device can be folded around the bending axis. In its folded state, the display screen can be seen from the outside of the device. Apple extends AppleCare + purchase period: users can decide within 60 days
