In accordance with the latest list published by the United States Patent and Trademark Office (USPTO), Apple has been granted a patent for under-screen Face ID technology, meaning that future iPhone models could have the front-facing camera embedded below the display of the device.
According to Apple’s description of this patent, under the screen will be embedded a variety of sensors, such as sensors for Touch ID, sensors for detecting three-dimensional non-contact gestures (“air gestures”), pressure sensors, position sensors, orientation sensors, and motion sensors (e.g.) Sensors such as accelerometers, magnetic sensors (e.g., compass sensors, gyroscopes and/or inertial measurement units containing at least one of these sensors), and health sensors are just a few of these sensors.

A variety of optical sensors are located beneath the screen, including self-mixing sensors (self-mixing sensors) as well as light detection and ranging (LIDAR) sensors that are designed to collect time of flight (time of flight), humidity sensors, moisture sensors, gaze tracking sensors, and other sensors as well.
In addition to the patent being altered, another change is the location of Dynamic Island, which is a feature that selectively activates and deactivates pixels by using a series of tiny, transparent windows whose size and location can be moved around the display in direct relation to the active pixels.
The conventional screens used in Apple’s devices have 13 layers, and Apple claims that light transmission through those areas is reduced by up to 80 percent. This means that Apple may, in the future, need to reduce the number of layers containing sensor areas on their screens.
