The in-display fingerprint scanner uses the chip Synaptics which has a model name ID FS950 and designed to perform well with an 18:9 and 20:9 orientation. This built-in sensor is a CMOS device which is situated just below an AMOLED screen. It works when the finger is illuminated and the sensor reads the reflections of the finger scan.

To make finger illuminated, first you need to lighten up the screen and then finger scanner will be able to read the reflection in between the AMOLED pixels. The setup is placed in a way to judge when to activate the sensor and light-up appropriate part of the screen only.

Amazingly, the process just takes 0.7 seconds only which is better than 1.4 seconds time taken by face recognition sensor. The Clear ID SF9500 scanner measures 0.69mm in thickness.
