It is reported that OPPO, OnePlus and other iterative new machines are testing ultrasonic under-screen fingerprints, which is expected to replace optical solutions

Thanks to netizen Xiao Zhanqieke for submitting the clue! On April 7, according to the latest news from blogger @digitalchatstation, OPPO, OnePlus, and realme iteration flagships are all testing ultrasonic screen fingerprints. If everything goes well, they will all replace ultra-thin optical solutions.

It is understood that both ultrasonic fingerprint and optical fingerprint are mature unlocking technologies at present. The former has better ease of use and higher security, but due to cost or other issues, not all Manufacturers are willing to pay for this. Currently, iQOO 12 Pro, Meizu 21/21 Pro, etc. are among the few models that use ultrasonic fingerprints. Ultrasonic fingerprint unlocking technology refers to the use of ultrasonic characteristics to identify fingerprints. When your finger is placed on the fingerprint reader, the fingerprint reader emits ultrasonic waves. When the ultrasonic waves encounter the texture of the fingerprint, they are reflected, thereby forming a fingerprint image. These images are then processed and compared to fingerprint templates stored on the device to determine a match. Optical fingerprint unlocking technology uses light and optical principles to identify fingerprints. When your finger is placed on the fingerprint reader, the fingerprint reader emits light, and the light is reflected when it encounters the texture of the fingerprint, thereby forming a fingerprint image. These images are then processed and compared to fingerprint templates stored on the device to determine a match. In addition to European and American manufacturers, it was previously reported that the new flagship of Xiaomi Snapdragon 8 Gen 4 is testing the domestic single-point ultrasonic fingerprint unlocking. The internal product progress is now ahead of schedule again, and the straight-curved dual-size strategy remains unchanged. Xiaomi is expected to 15 series. If the news is true, ultrasonic fingerprint unlocking will be popularized in more flagship models this year or next year, which can be said to be good for consumers, and everyone can look forward to it.
