World’s first fingerprint scanner ‘under display’

Aiming to take on tech giants Samsung and Apple, Chinese smartphone maker Vivo on Wednesday launched the industry-first under display fingerprint technology that will strike out the need of a physical button to unlock the device.

Called Vivo Under Display, the technology was unveiled at MWC 2017 in Shanghai.

Based on Qualcomm Fingerprint Sensors - that was launched earlier in the day -- this sensor can be placed under the glass (0.8mm), an OLED screen (1.2mm) and an aluminum cover (0.525mm), making it invisible yet fully functional.

Vivo uses the ultrasonic technology in its sensor that emits ultrasonic waves that capture a precise image of a user’s fingerprint to unlock the device.

The water resistant technology even omits the limitations that Capacitive fingerprints face and can unlock devices even if the hands are wet.

What makes this technology superior is the fact that the sensor can be placed anywhere under the display.

The c o mpany a l s o launched the Digital Signal Processing (DSP) solution for backlighting and nighttime photography.

The technology not only saves time by fast photo processing but also minimises the noise. Vivo also unveiled the Hi-Fi audio solution with DAC chip that improves the audio quality. IANS
