Apple's new patent exposed: Spring layer design may greatly improve the drop resistance of folding screen iPhone

News on April 17, although the iPhone has not yet been launched, Apple has been quietly researching and developing in this field for many years. Currently, some key technical problems such as screen creases and drop resistance are still being overcome, hindering mass production of products. However, the latest patent information reveals that Apple may have found a new way to enhance the screen's drop resistance.

According to the editor’s understanding, in the information recently released by the United States Trademark and Patent Office (USPTO), Apple was granted a patent for a folding screen mobile phone. The patent mainly introduces an innovative spring layer design, which is composed of an array of metal springs with embedded sensors such as variometers. These springs can be made of various flexible metals, such as spring steel, nickel-chromium alloy, etc. If necessary, Apple is also considering combining compressible structures such as foam columns with springs to further optimize the performance of the spring layer.

Apple states that the design of this spring layer can effectively relieve the external pressure of the device when it is impacted or squeezed. At the same time, it It can also reduce the stress on the screen during frequent folding and unfolding, thereby significantly improving the durability of folding screen devices. In addition, another Apple patent also demonstrates screen self-healing technology, which covers the screen with a layer of self-healing material to reduce creases and scratches.

The gradual exposure of these innovative technologies shows that Apple’s accumulation of folding screen technology is becoming increasingly rich. In the future, once the foldable screen iPhone comes out, Apple may gain a significant lead in this market.

The above is the detailed content of Apple's new patent exposed: Spring layer design may greatly improve the drop resistance of folding screen iPhone. For more information, please follow other related articles on the PHP Chinese website!
