The patent shows that two fingerprint sensors under the screen will be located in the same place, communicating with the same module on the main board of the smartphone. Thus it will help to save space inside. SamMobile says Samsung can use a combination of ultrasonic and optical sensors.

With this special design, users can unlock the device or authenticate a payment transaction no matter which screen they are on.

Currently, there is no folding screen smartphone equipped with an in-display fingerprint sensor. Maybe the main reason is because folding screen smartphones often have an external secondary screen design and an internal main screen, so the design to place the fingerprint sensor under the screen will not be really convenient. But with Samsung’s patent, it is completely possible to overcome that inconvenience and open a pioneering direction.
