Categories Biometric R&D  |  Biometrics News

A Samsung patent filed with WIPO for a ‘Biometric sensor and device including the same’ was published today and details the working of an optical in-screen fingerprint scanner.

Spotted by LetsGoDigital, the patent application explains how it is important to maintain a constant distance between an optical sensor and the display for it to work correctly.

Samsung describes a system in which the fingerprint sensor is etched to an opening on a printed circuit board to ensure that a safe distance from the display is maintained. It also describes how Samsung wants to place the sensor under the screen and how the region around the sensor is pressure-sensitive.

Samsung has applied for a few in-display fingerprint scanner patents this year fueling speculation that the Korean company is developing its own fingerprint scanner for the Galaxy S10.
