After the release of the iPhone 7, the new flagship of Xiaomi, Xiaomi 5S, will soon be available. A few days ago, the Anbi Bunny database has appeared in the figure of Xiaomi 5S, and some configurations and running points are also exposed. Configuration information shows that Xiaomi 5S still uses 5.15-inch 1080p display, equipped with Snapdragon 821 processor, the current running score is about 150,000 points, running Android 6.0.1 system. Memory, camera and other information are still not clear, but compared to Xiaomi 5, it will definitely improve.
In addition to the Snapdragon 821 processor, the Xiaomi 5S obviously has other heavy weapons.
Today, IHS Technology China Research Director Wang Yang @Kevin Wang's diary broke the news on Weibo: "The supply chain shows that Xiaomi 5S uses Qualcomm's ultrasonic fingerprint recognition technology to hide the sensor under the glass, on the glass cover of the mobile phone. No punching. This is the industry's first "Under glass" fingerprint recognition phone."
Ultrasonic fingerprint recognition technology is called the representative of the third generation fingerprint recognition technology. Its principle is to use ultrasonic waves to have the ability to penetrate materials, and to produce echoes of different sizes depending on the material (the ultrasonic waves are absorbed when they reach different material surfaces, The degree of penetration and reflection is different. Therefore, by using the difference in sound impedance between skin and air, it is possible to distinguish the position where the fingerprint is located.
