Although Apple has been slow to launch a foldable screen iPhone, it has actually been developed internally for many years, but some hardware problems have not been solved yet and it has not been mass-produced, such as screen creases and resistance to falling.
However, the latest patent information shows that Apple has found a way to improve the screen’s drop resistance.
According to a list recently announced by the United States Patent and Trademark Office (USPTO), Apple has obtained a patent for a foldable screen mobile phone, focusing on a new spring layer concept to reduce pressure when folding.
According to reports, this spring layer is composed of a metal spring array, and then sensors such as force sensing structures (such as strain gauges) are embedded in the spring layer. Various flexible metals can be used, such as: spring steel, nickel-chromium aluminum alloy, Beryllium copper alloy, stainless steel, cobalt-nickel alloy and other spring metals. If necessary, foam posts can be interspersed with other compressible structures and springs to help adjust the effectiveness of the spring layers.
According to Apple, the introduction of a spring layer into a foldable screen device can relieve the external pressure on the device in events such as impact and squeezing. It can also relieve the stress on the screen during repeated folding and unfolding, thereby improving the performance of the foldable screen device. of durability.
In addition, a previous Apple patent also realized self-healing of the screen, which can cover the screen with a layer of “self-healing” material to reduce creases and scratches.
There are various signs that Apple’s foldable screen technology is becoming more and more perfect, and it may be significantly ahead of its competitors after the launch of the foldable screen iPhone.
