Today, Qualcomm announces its second-generation in-display fingerprint sensor called 3D Sonic Gen 2. Unlike many other optical in-display fingerprint solutions, Qualcomm is still ultrasonic, which means it uses sound waves to search for 3D functions. on a user’s fingerprint.
The first generation of Qualcomm’s 3D sonic sensor was included in Samsung’s Galaxy S10, Note10, S20, and Note20 series and its performance and reliability were often questionable. Accuracy and speed were not on par with other on-screen optical solutions from Chinese OEMs such as OnePlus and Huawei, many of which currently use faster and more accurate optical solutions (compared to ultrasonics).
The next-generation Qualcomm 3D sonic sensor promises to be 50% faster than its predecessor and 77% larger. One of the highlights of the first-generation sensor was that the activation area was quite small and it was difficult to find the scanner accurately by feeling alone.
For reference, the Generation 1 scanner was 4 x 9mm, while the new sensor will measure 8 x 8mm and allows the sensor to capture 1.7 times more biometric information. The new sensor will also measure just 0.2mm thick in the scan area, allowing for the ability to integrate on-screen scanners into flexible panels of folding devices. We wonder if this means that Samsung’s foldable devices will have on-screen scanners this year.
Qualcomm says the second-generation 3D sonic sensor will debut on smartphones “in early 2021.” Perhaps Samsung can use this new in-display sensor in the new Galaxy S21 series, which is expected to debut in less than a week.
