What about screen fingerprints

Under-screen fingerprint recognition is currently divided into light-sensitive fingerprint recognition and ultrasonic fingerprint recognition. Its working principle is to use the internal sensor to emit a light/ultrasonic fingerprint signal, and then compare it with the original recorded fingerprint. If the fingerprint is the same, the unlocking can be completed. Among them, the ultrasonic receiver performs processing to obtain the fingerprint information and then compares it with the originally recorded fingerprint. If the fingerprint is the same, the unlocking can be completed. Through this process, under-screen fingerprint recognition can achieve a high degree of security and accuracy.

Under-screen fingerprint scanners can further increase the screen-to-body ratio and promote the true popularity of full-screen displays. In addition, through penetration recognition technology, the recognition process can be completed even under water, and it can be used normally in multiple usage scenarios.

Unlocking operations are mostly similar to the push-type fingerprints we used before, but at present, under-screen fingerprints are still in the development stage, and the unlocking speed and accuracy are still far behind capacitive fingerprints, especially when wet. It is basically impossible to unlock if your hands or fingers are stained.
