This can be used on the screen, behind the metal shell, or even in the frame.The Vivo Under Display fingerprint unlocking solution is based on Qualcomm Fingerprint Sensors. The ultrasound from the sensor can penetrate an OLED display that is 1.2mm thick to recognize user fingerprint.
This uses piezoelectric effects to produce and receive ultrasonic signals that pass through the OLED screen. This produces different reflection strengths at the fingerprint ridges and fingerprint valleys. It generates a fingerprint image, achieving fingerprint identification under the display.This doesn’t require a physical button for the fingerprint sensor and allows a true full-screen display and an integrated unibody and mechanical waterproofing design.
Regarding the Vivo Under Display, the company said: Compared to traditional capacitive and optical fingerprint recognition technologies prevalent in the industry, Vivo Under Display has tremendous advantages in terms of waterproofing and anti-ambient light.
