Apple has won the patent for off-screen Face ID technology, further enriching the smart island ecology of iPhone.

CTOnews.com, February 8 (Xinhua)-- according to the latest list released by the U.S. Trademark and Patent Office (USPTO), Apple has obtained a patent for an off-screen Face ID, which means that future iPhone models can embed a front-facing camera at the bottom of the screen.

CTOnews.com looked at the description of Apple's patent, and Apple said it could embed a variety of sensors at the bottom of the screen, including sensors for Touch ID, sensors for measuring three-dimensional contactless gestures ("air gestures"), pressure sensors, sensors for detecting position, direction and motion (e.g. Accelerometers, magnetic sensors (such as compass sensors, gyroscopes, and / or inertial measurement units containing some or all of these sensors), health sensors, and so on.

The sensors at the bottom of the screen also include a variety of optical sensors, such as self-mixing sensors (self-mixing sensors) and light detection and ranging (lidar) sensors that collect time of flight (time-of-flight), humidity sensors, moisture sensors, gaze tracking sensors and other sensors.

The location of the smart island has also been changed in the patent. By using a series of tiny transparent windows, the apparent size and position of these windows can be effectively moved around the display, selectively activating and deactivating different pixels.

Apple says its devices use 13 layers of traditional screens, and light transmission through these areas has been reduced by up to 80%, so it may need to reduce the number of layers containing sensor areas in the future.
