Screen fingerprint recognition technology is already a must-have technology for many mobile phones, what is innovative in this regard? Samsung's latest patent show that they have to provide double-sided screen fingerprint recognition technology for next-generation folding screen, Samsung's Galaxy Z Fold 4 is expected to start.
On March 31, 2021, Samsung Electronics submitted a & ldquo to the World Intellectual Property Office (WIPO); patents for foldable electronic devices that can be detected by at least part of the display screen.

Foreign media LetSgodigital has made a mobile phone simulation effect, Samsung intends to handle fingerprint sensors in such a way that it can be used in external screens, or it can be used as a tablet for a tablet. The essence is A double-sided fingerprint sensor.
To achieve this, the fingerprint sensor integrates the lower left half of the flexible screen, which can be used two-way & mdash; & mdash; allows biological identification certification in the deployment and closing position, a small printed circuit board (PCB) is placed between the sensors, passed Additional cables are connected to the phone motherboard.
