this presentation is on the Fingerprint under the display and how it works

1. Fingerprint Scanner
Under The Display
Presented By: Kshipra Garg

3. Types of Fingerprints

4. Optical Scanner
Scanning process starts when you place your finger on a glass plate and a CCD camera
(Charge Coupled Device) takes a picture and compares whether the image is
corresponding.

5. Capacitive Scanner
Like optical scanners, capacitive fingerprint scanners generate an image of the
ridges and valleys that make up a fingerprint. But instead of sensing the print using
light, the capacitors use electric current.

6. Synaptics fingerprint sensor
It works behind metal part, glass part even display

8. Qualcomm
Snapdragon Sense ID fingerprint technology

9. OLED Screen
OLED (organic light-emitting diode) panels are made
from organic (carbon based) materials that emit light
when electricity is applied through them. Since OLEDs
do not require a backlight and filters (unlike LCD
displays), they are more efficient, simpler to make, and
much thinner - and in fact can be made flexible and
even rollable. OLEDs have a great picture quality -
brilliant colors, infinite contrast, fast response rate and
wide viewing angles.

10. Implementation
Last year Samsung has planned to do something like that with their
Samsung Galaxy S8 by they can not do on time so they skip this part.
But now vivo shows their VIVO X20 plus where the power of synaptics is behind.
