As report goes,Qualcomm's second generation of ultrasound fingerprint sensors are in progress and are expected to appear in the second half of this year.

Compared with the first generation,The recognition area of the second generation 3D acoustic fingerprint technology is larger, ranging from 9 x 4 mm (36 mm).Two) Increase to 8x8mm (64mm)TwoAt the same time, the thickness remains unchanged (200 um)。 By contrast, the optical fingerprint module has a thickness of 3 mm.

Gordon Thomas, a Qualcomm official, said that the 3D acoustic fingerprint consists of three components: ASIC (dedicated circuit driver), FPC flexible circuit board and sensors, and the sensors are not made of silicon wafers, which greatly increases production and reduces costs.

Judging from the time point, the second generation of ultrasound fingerprints may be used as soon as possible from Samsung Galaxy Note 10.
