Qualcomm Unveils 2nd Gen. In-Display Fingerprint Sensor
Jan 11, 2021, 3:00 PM by Rich Brome
Qualcomm has introduced 3D Sonic Sensor Gen. 2, a new and improved version of the ultrasonic, in-display fingerprint sensor used in the Samsung Galaxy S10, Note10, S20, and Note20 series. The new sensor is 50% faster and has a 1.7x larger sensing area. The sensor itself is just 8 x 8 x 0.2 mm, allowing it to fit under the display without impacting phone size. (The first-generation sensor was 4 x 7 x 0.2 mm.) This line of standard-size sensors is not to be confused with 3D Sonic Max, a much larger sensor at 20 x 30 mm. Ultrasonic fingerprint sensors have an advantage of working even while the surface or finger is wet. Qualcomm 3D Sonic Sensor Gen. 2 is expected to debut in mobile devices early this year.
