Qualcomm 3D Sonic Under-Display Fingerprint Sensor Announced; Could Be Seen in Galaxy S10
Dec. 5, 2018We knew the company is working on a new sensor that can live under the display, and Qualcomm has announced the3D Sonic Sensor at its Tech Summitin Maui, Hawaii last night. The sensor uses ultrasonic waves, unlike current-gen technology which instead shine a bright light on to your finger to illuminate the ridges and read the print. Qualcomm claims the sonic part of the sensor makes it more secure and accurate.
The ultrasonic scan reads the ridges and details of fingers in 3D, so it can work through water or oil or grime, situations where today’s under-display fingerprint sensors just are not reliable.
It fits in the same space occupied by the optical scanners, so there’s no disadvantage here.
