Mobile World Congress 2017 is underway in Shanghai, China - with Vivo teasing their new fingerprint sensor technology that has been embedded under the display. An impressive trick that the world thought Apple would be first to market with.
The new 'Under Display Fingerprint Scanning Solution' is based on Qualcomm's technology, and was shown off on a prototype iteration of Vivo's Xplay 6 smartphone. Vivo told Engadget: "In Vivo's R&D plan, fingerprint scanning will not be carried out by an independent button or region. It will be realised more subtly under the screen, behind the metal shell, or even in the frame. Based on ultrasonic technology, the fingerprint recognition technology can be further expanded to realize user interaction, such as gesture recognition, security verification and other fields, which will greatly enhance user experience".
The technology does allow for the fingerprint sensor to be placed all over the display, but has been limited to the lower half of the display for the prototype. Secondly, the fingerprint sensor being available all over the display also drives up the cost significantly, according to Vivo.
