One of the biggest problems in devices with folding screens Currently, there is the possibility of marks or grooves appearing in the place where the fold occurs — many people even argue that this is one of the reasons why Apple has not yet launched a device of this kind.
While recent rumors indicate that this day is getting closer and closer, Maçã continues with its research in the search for a screen construction technology that avoids creases — one of which was even detailed in a patent application recently registered by company.
As noted by the Patently Apple, the patent can be applied to both smaller devices (such as an iPhone and an iPad) and larger screens (such as a MacBook). Basically, Apple’s idea is to chemically create a textured glass in the place where the fold will occur to prevent the formation of the crease.
This would be possible thanks to a groove, which would make the glass that covers the display thinner, so that the area can also be filled with a type of polymer — a flexible liquid plastic that would help the display to better “shape” the surface of the screen. , making it completely flat and without marks.
The inner surface of the groove would be quite irregular (even rough), which would result in fewer light reflections and help the glass adhere better to the polymer — which would be hardened (or cured, in scientific language) through techniques such as application from ultraviolet light, heating or catalysts.
O patent application [PDF] was released yesterday by the United States Patent and Trademark Office, under number 20240079442.
