At least two of the Galaxy S10 versions that will be launched next year will be equipped with on-screen fingerprint sensors. Reports suggest that Samsung could use ultrasonic sensors instead of optical sensors available on competing devices. However, two patent applications reveal that Samsung has spent a lot of time perfecting optical display fingerprint sensors, suggesting that various Samsung phones could use this technology in the near future.
Last week, we reviewed the documentation describing a Samsung device with a built-in sensor on the screen, suggesting it would be located near the bottom of the screen. But the Dutch blog Let's go digital discovered a second patent application filed with the USPTO and the WIPO earlier this year and published on October 18.
titled Method of acquiring biometric information and electronic device supporting them, the patent application describes the progress of digitization of fingerprints.
Samsung suggests different locations for the actual fingerprint sensors, including above the screen (131a sensor in the image above), in the display (132b) or below the screen (131c). The language seems to suggest that in future devices, the fingerprint sensors in display can work regardless of where the user touches the screen.
The application notes that a low-power processor, which could represent the core of an efficient octa-core chip design, would handle the biometric sensor, touch sensor, and sensor light to initiate sweeping and quick unlocking of the screen.
When the system detects a user's finger, it automatically performs various analyzes by modulating the brightness of the display area where the finger touches the screen. The screen could display additional content above the detection and scanning area, likely to provide assistance to the user regarding the task at hand. The illustrations show a credit card image appearing on the screen when the biometric sensor authenticates a payment.
The interest of this patent is that Samsung uses an illustration showing a device with a notch in the documentation. Samsung has so far avoided the notch designs on its Galaxy phones. In addition, the patent contains smartphone images that would recall previous Samsung models to the Galaxy S6. Comparatively, the previous patent included camera images much like the modern designs of the Galaxy S9.
