While Apple and Samsung are said to be struggling for implementation of in-screen fingerprint sensor on their new devices, the Chinese OEM, Vivo now seems to have overhaul the tech giants. The company at Mobile World Congress Shanghai 2017 on Wednesday showcased its new ‘Under Display Fingerprint Scanning Solution’ based on Qualcomm technology.
Qualcomm along with Vivo demonstrated the new fingerprint scanning technology by using the Vivo Xplay 6 phone. Vivo claimed that the ‘under-display’ fingerprint solution is the “first to be demonstrated by a smartphone manufacturer”. The company further said that since the new ‘Under Fingerprint Display Scanning Solution’ doesn’t require a physical button for the sensor, the technology will enable the use of “true full-screen display and an integrated unibody and mechanical waterproofing design”.
Vivo in a statement (via MacRumors) explained, “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”. The company further added, “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”.
While Vivo has got the first dibs on the new fingerprint sensor technology, Endgaget which says to have tested with a prototype based on the existing Vivo Xplay 6 cited that the recognition area was small and the recognition speed was ‘noticeably’ slower. Vivo however, told the publication that although the fingerprint scanning function was confined to a ‘small region’ on the prototype units, in theory the same sensing technology could be applied across the entire screen, but that would significantly increase production cost.
Vivo didn’t mention the ‘timeline’ as to when it will bring devices that are integrated with this technology. Qualcomm, however in a press statement said that the sensors for displays are expected to be available to manufacturers for evaluation in the fourth quarter this year. The US-based telecommunication firm also said that the technology will work through glass and metal apart from display. The technology will be capable of scanning through OLED display stacks of “up to 1200µm”. Qualcomm fingerprint sensors for glass and build will be integrated into phones which will have Snapdragon 660 and Snapdragon 630 mobile platform. While the advanced fingerprint sensors for ‘display’ is said to work with future Snapdragon platforms and non-Snapdragon platforms as well.
