Description
Technical Field
The utility model relates to a cell-phone protection film field.
Background
Ultrasonic fingerprinting has a number of unique advantages over capacitive touch screen based fingerprinting, including the ability to scan through smartphone housings made of glass, aluminum, stainless steel, sapphire, or plastic. This unique advantage provides flexibility for the OEM customers of Qualcomm Technologies to design a new generation of elegant, innovative and differentiated terminals.
In addition, the user experience is improved in that the scanning can be free from dirt possibly existing on the finger, such as sweat, hand cream or condensation, and the like, so that a more stable and accurate authentication method is provided. In addition, the QTI ultrasound-based solution utilizes sound waves to directly penetrate the surface layer of the skin to identify three-dimensional details and unique fingerprint features, including fingerprint ridges and sweat pores, that cannot be identified by current capacitive touch screen-based fingerprint technology. This can produce a surface map of the fingerprint that is rich in detail and difficult to copy.
