[0002] Fingerprint unlocking of mobile phones is a convenient and secure way of identity verification, with the following characteristics and working principles:

[0003] Working Principle:

[0004] Fingerprint unlocking of mobile phones is usually based on capacitive, optical or ultrasonic technology.

[0005] Capacitive fingerprint unlocking: The sensor detects the tiny capacitance differences caused by the valleys and ridges of the fingerprint to identify the fingerprint. When the finger touches the sensor, the capacitance formed between the raised part (ridge) of the fingerprint and the sensor electrode is larger, while the capacitance formed by the concave part (valley) is smaller. The system constructs a fingerprint image by measuring these capacitance differences.

[0006] Optical fingerprint unlocking: Use light to irradiate the finger, and the reflected light is captured by the sensor. According to the texture of the fingerprint and the different reflections of light by the ridges and valleys, a fingerprint image is formed.

[0007] Ultrasonic fingerprint unlocking: The sensor emits ultrasonic pulses. When encountering the finger, part of the sound wave is reflected back, and a three-dimensional image of the fingerprint is drawn according to the time and intensity of the reflected wave.

[0008] Advantages:
