Difference between optical and under-screen fingerprints

Different working principles and different recognition speeds.

1, the working principle is different: optical under-screen fingerprint is through the optical sensor under the screen to obtain fingerprint images, while under-screen fingerprint is through the ultrasonic sensor under the screen to obtain fingerprint images.

2. Different recognition speeds: The recognition speed of optical under-screen fingerprint is slow, requiring users to press their fingers on the screen to complete the recognition, while the recognition speed of under-screen fingerprint is fast, users only need to gently press their fingers on the screen to complete the recognition.
