Foldable smartphones released over the past year have one significant drawback – the increased fragility of the display at the bend. After a certain amount of folding, the screen is deformed, microcracks and “dead” pixels appear on it. Apple’s new patent offers a solution to this problem.
It is proposed to use special protective layers as a solution. Apple has developed several options, including hard coating on a transparent substrate to form a protective layer structure. In this case, such a coating will be able to survive a large number of bends, withstanding prolonged loads, and will become much more effective than existing analogues.
According to Apple engineers, display damage is caused by microcracks. The patent considers the option when a solid protective layer fills the cracks that are formed, avoiding the appearance of new chips and scratches.
According to the description of the document, this technology can be applied to smartphones, smart watches, televisions, laptops, tablets and all-in-ones.
Given the fact that this is not the first Apple patent related to flexible devices, it is highly likely that a foldable iPhone, iPad or other “apple” gadget will appear in the future.
