Another company offers a creative solution that will enable the integration of elongated screens with tiny margins and fingerprint scanners in an optimal front position
Yesterday, the new Vivo X20 Plus UD was officially unveiled, the first smartphone on the market Which includes a fingerprint scanner under the display panel And does not force the consumer to choose between an enlarged screen and a medium Security You are the most comfortable. This may not be a fundamental revolution of the entire smartphone market, but it is a small step forward that could bring more devices to enjoy a larger screen of the same physical dimensions.
This first Synaptics technology application that allows for the long-awaited integration has a few drawbacks: relatively long response times for the fingerprint scanner, increased cost compared to simpler scanners - and especially the use of screens in technology OLED Because it is not based on an entire backlight unit and is therefore able to allow the scanner to operate through it.
Now, the company Japan Display Which sells primarily from the field of display reveals its own interesting solution that will allow screens and scanners to operate in synergy - when the scanner is above the screen, in fact. It is a unique technology that enables port Fingerprint scanner But rather based on a thin, semi-transparent glass surface based on light returns from the finger to characterize, define, and compare it to existing data.
Such technology will allow for "invisible" biometric scanners in almost any product with greater ease and convenience, and will allow us to get front-facing scanners also with standard LCD technology panels, seemingly cheaper for Synaptics (thanks to much simpler integration) and maybe even temporary Shorter response that is or is the same as the silicon sensors.
We do not yet know when exactly we will be able to see this JDI technology on real commercial devices, but it may well be a significant line to the field - enabling us to survive the wait until the ultrasonic finger scanners can already operate through different surfaces like glass or metal while That they are "absolutely" transparent to them. Absolutely interesting.
