On April 14th, besides iPhones, in-screen fingerprint recognition has almost become a standard feature for current flagship smartphones, with optical and ultrasonic fingerprint technologies being the main choices for smartphone manufacturers.
Recently, digital blogger "Digital Chat Station" revealed in a post that Himax disclosed during a conference that they had shipped ultrasonic fingerprint sensors by the end of last year, supplying them in small quantities to the blue factory (vivo).
The top 5 mainstream domestic manufacturers are currently testing, except for one with relatively deep ties with MediaTek. They are expected to deploy on new devices powered by Snapdragon 8 Gen4 and Dimensity 9400, featuring smaller chip size and lower cost.
It's worth mentioning that, according to the blogger, the vendor closely associated with Qualcomm offers two options: optical fingerprint and Qualcomm ultrasonic, in addition to 3D face recognition.
When replying to the comment, he also mentioned that in the top 5, there's one company all in on QCM (Qualcomm), but Xiaomi isn't.
It appears that the company deeply tied to Qualcomm and not using the Goodix ultrasonic fingerprint technology may be Honor.
Ultrasonic fingerprint recognition operates by emitting ultrasound waves from sensors beneath the screen when a finger is pressed against it.
When the ultrasound encounters the ridges and valleys of a fingerprint, differences in absorption, penetration, and reflection create varying levels of echo, which are received by sensors to construct a 3D fingerprint image.
Compared to optical fingerprint recognition, ultrasonic fingerprint recognition offers stronger penetration, better resistance to water and dirt interference, higher recognition rates, support for live detection, and higher security.
So why haven't some flagships adopted ultrasonic fingerprint technology? The primary reason is cost.
According to previous statements from OnePlus and Meizu, the cost difference between ultra-thin optical fingerprint and short-focus optical fingerprint solutions is fourfold, while Meizu's ultrasonic fingerprint solution costs four times as much as ultra-thin optical fingerprint technology.
