Vivo X21 features In-Display Fingerprint Scanning Technology

In-Display Fingerprint Scanning Technology

When I first put my hands on the newest flagship smartphone of Vivo, the X21, I became curious with its revolutionary In-Display Fingerprint Scanner. This technology replaced the rear fingerprint sensor not only to achieve a sleek and unified design but also to offer an immersive smartphone experience.

So how does this the fingerprint scanner work?

When the user’s finger touches the screen for unlocking, the Vivo X21’s Super AMOLED display emits light to illuminate the finger. The optical fingerprint sensor below the OLED display captures the light reflected by the fingerprint. Based on the reflected light from the unique ridges on the fingerprint, the sensor processes the optical signals to deliver crisp and sharp fingerprint images for matching. The current unlocking speed is only 0.6 second. WOW!

Moreover, when fingerprint recognition is needed, such as when the screen is off and for unlocking apps, a fingerprint recognition icon will appear on the screen for users to press for immediate authentication. Otherwise, the fingerprint icon is invisible to ensure a seamless mobile experience.

The decision to mass produce the In-Display Fingerprint Scanning Technology was made after an extensive research into different biometric solutions in the market as well as consumer habits and market needs. To recall, Vivo has various research and development centers worldwide, including the United States (San Diego) and China (Shenzhen, Dongguan, Nanjing, Hangzhou, and Beijing).

Perfecting the In-Display Fingerprint Scanning Technology was no easy feat as it was a huge challenge to integrate the sensor to the Vivo X21’s internal design and screen. Vivo had to redesign the internal structure of the phone to make this vision come to life.

At MWC Shanghai 2017, Vivo unveiled the industry’s first Vivo Under-Display Fingerprint Scanning Solution. Then at CES 2018, the global smartphone brand displayed a ready-to-produce smartphone with the world’s first In-Display Fingerprint Scanning Technology.
