Comparable to its big brother Xiaomi 15! Redmi K80 Pro exposed to support ultrasonic fingerprint

According to news on July 31, blogger Digital Chat Station hinted that the Redmi K80 Pro will be equipped with an ultrasonic screen fingerprint, in line with its big brother Xiaomi 15 series, while the standard version of the Redmi K80 will have an optical fingerprint. In principle, the implementation of ultrasonic fingerprints is almost the same as that of mainstream optical fingerprints, both of which use reflection imaging of screen light to identify people's fingerprint information.

1. Ultrasonic fingerprint recognition

When the user’s hand presses the screen, the reflected light returns to the sensor under the screen through the pixel gap. Because fingerprints themselves are uneven, the reflected light is also different. Then, the algorithm is used to compare the previously input fingerprint images to achieve accurate identification.

2. Advantages of ultrasonic fingerprint

Ultrasonic fingerprint can further utilize the unique pulse reflection characteristics of ultrasonic waves to generate corresponding 3D depth data in real time. It can measure the distance between the fingerprint surface and the skin and determine the pattern of the fingerprint. Therefore, clean, dirty, and wet fingerprints can be accurately collected.

3. Redmi K80 Pro

In addition to supporting ultrasonic fingerprints, Redmi K80 Pro is equipped with Qualcomm Snapdragon 8 Gen4 platform and uses a 2K OLED flexible straight screen. This will be Redmi’s most powerful high-end flagship.

4. Redmi K80

Standard version Redmi K80 is expected to be equipped with Qualcomm Snapdragon 8 Gen3 platform. The screen is also a 2K direct screen. The new product will be launched in Q4 this year.
