Compared with the fingerprint technology based on capacitive touch screen, ultrasonic fingerprint unlocking technology has many unique advantages, including scanning through the smart phone shell made of glass, aluminum, stainless steel, sapphire or plastic. This unique advantage provides the OEM customers of Qualcomm Technology Company with the flexibility to design a new generation of elegant, innovative and differentiated terminals.
In addition, the improvement of user experience is also reflected in the fact that scanning can be free from the influence of dirt such as sweat, hand cream or condensation on fingers, thus providing a more stable and accurate authentication method. In addition, QTI's ultrasonic-based solution uses sound waves to directly penetrate the skin surface, and identifies three-dimensional details and unique fingerprint features, including fingerprint ridges and pores, which cannot be recognized by the fingerprint technology based on capacitive touch screen at present. This can produce a fingerprint surface map with rich details, which is difficult to imitate.
Advantages of ultrasonic fingerprint unlocking technology;
Advantage 1: The most obvious advantage of ultrasonic unlocking is fast unlocking speed and accurate identification. Compared with the traditional optical fingerprint unlocking, the ultrasonic fingerprint unlocking speed is several times faster and the accuracy is much higher, so the unlocking experience is better.
Advantage 2: Ultrasonic fingerprint input is simple. Traditional optical fingerprint input needs more than ten times to succeed, while the ultrasonic fingerprint of iQOO8 Pro just released only needs to be input once, which is very simple and practical.
