On April 14th, apart from iPhones, screen fingerprint recognition has become almost a standard feature for current flagship phones, with optical and ultrasonic fingerprint being the main choices for smartphone manufacturers.
Recently, digital blogger "Digital Chat Station" revealed in a post that Himax disclosed at a conference that they had shipped ultrasonic fingerprint sensors by the end of last year, supplying them in small quantities to a blue factory (likely referring to vivo).
The top 5 mainstream domestic manufacturers are currently testing, with one of them having deep integration with Unicom. It is expected to be implemented in the new machines featuring Snapdragon 8 Gen4 and Dimensity 9400, with smaller chip size and lower cost.
The blogger noted that, according to their information, manufacturers closely tied with Qualcomm have two options: optical fingerprint and Qualcomm ultrasonic. Additionally, this manufacturer also has a 3D facial recognition solution.
When responding to the comments, he also revealed that among the top five, there's one company "All in QCM" (Qualcomm), but Xiaomi isn't among them.
It appears that the company deeply tied to Qualcomm and not using the Goodix ultrasonic fingerprint solution could be Honor.
Ultrasonic fingerprint recognition operates on the principle of emitting ultrasonic waves from sensors beneath the screen when a finger presses against it.
As the ultrasonic waves encounter the ridges and valleys of the fingerprint, the degree of absorption, penetration, and reflection varies, generating different energy echoes received by the sensor, thus constructing a 3D fingerprint image.
In comparison to optical fingerprint recognition, ultrasonic fingerprint recognition boasts strong penetration, high resistance to water and stain interference, high recognition rates, support for live detection, and higher security.
Why haven't some flagships adopted ultrasonic fingerprint technology yet? The primary reason is cost.
According to previous statements from OnePlus and Meizu, the cost difference between ultrathin optical fingerprint and short-focus optical fingerprint is fourfold, while Meizu's ultrasonic fingerprint solution costs four times that of ultrathin optical fingerprint.
