Fast technology news on May 13, tonight, vivo image flagship vivo X100 Ultra was officially released, with a price starting at 6499 yuan.
According to Goodix, the vivo X100 Ultra is the first to be equipped with Goodix's independent intellectual property rights for ultrasonic fingerprint solutions.
Based on Goodix's self-developed CMOS sensor architecture and wafer-level acoustic layer processing, the new ultrasonic fingerprint solution has a better signal-to-noise ratio and can obtain clearer fingerprint images.
The solution supports second-speed recognition, even if the oil finger or wet finger can be recognized and unlocked.
It is understood that the scheme uses low-voltage drive, which greatly reduces the power consumption of the sensor and simplifies the hardware design.
Goodix said that the ultra-thin thickness of the chip module frees up more internal space for key components of mobile terminals, making the unlocking area design more flexible and more comfortable to unlock.
It is reported that the vivo X100s series released tonight is equipped with Goodix's under-display optical fingerprint and AMOLED touch solutions.
At the same time, the vivo X100 Ultra and vivo X100s also use Goodix's intelligent audio amplifier and audio software solution.
Note: The principle of ultrasonic fingerprint recognition is that the finger presses the screen, and the sensor under the screen emits ultrasonic waves to the finger pressing area.
When the ultrasonic wave comes into contact with the "crest" and "yu" of the fingerprint, the degree of absorption, penetration and reflection is different, and echoes of different energies will be generated and received by the sensor, so as to construct a 3D fingerprint image.
Compared with optical fingerprint recognition, ultrasonic fingerprint recognition has strong penetration, strong resistance to water and stain interference, high recognition rate, support for liveness detection, and high security.
