Fast science and technology news on April 17thKingbillycasinonodepositbonusAlthough Apple has been unable to launch the folding screen iPhone for a long time, it has been researched and developed internally for many years, but some hard problems have not been solved, such as screen creases, poor resistance to falling, and so on.

But the latest patent information shows that Apple has found a way to improve the falling resistance of the screen.

According to a recent list released by the US Trademark and Patent Office (USPTO), Apple has obtained a patent for folding screen phones, focusing on a new concept of spring layer to reduce the pressure of folding.

According to reports, the spring layer is composed of a metal spring array, and then force sensing structures (such as strain gauges) and other sensors are embedded in the spring layer, and various flexible metals can be used. for example, spring steel, Ni-Cr-Al alloy, beryllium copper alloy, stainless steel, Co-Ni alloy and other spring metals.

If necessary, foam columns and other compressible structures can be interspersed with springs to help adjust the performance of the spring layer.

According to Apple, the introduction of a spring layer into a folding screen device can alleviate the external pressure on the device in events such as impact and extrusion, as well as the stress effect on the screen in the process of repeated folding and unfolding, thus improving the durability of the folding screen device.

In addition, a previous Apple patent also allows the screen to repair itself, which can be covered with a layer of "self-healing" material to reduce creases and scratches.

There are signs that Apple's folding screen technology is improving and may be well ahead of its competitors with the advent of the folding screen iPhone.
