It House, March 17 (Xinhua)-- according to the latest list released by the US Trademark and Patent Office (USPTO), Apple has obtained a new patent for foldable phones that automatically fold the screen to minimize screen damage while detecting that the iPhone / iPad with a flexible screen is falling.

The new patent is called "self-retractable display devices and technologies using drop detection to protect screens". The description of some of the patents translated by IT House are as follows:

A mobile device with a foldable and scrollable display can use a sensor to detect vertical acceleration (for example, acceleration relative to the ground) to determine whether the device is in a falling state.

If the sensor detects that the mobile device has fallen, the foldable device can at least partially retract to prevent the fragile display from hitting the ground.

When the vertical acceleration exceeds a predetermined threshold, the release mechanism of the hinge connection between the first display and the second display of the electronic device can be activated. The reel device can be retracted automatically.
