Japan Display Develops Transparent Fingerprint Sensor

Fingerprint sensors hidden behind a touchscreen are heading to new smartphones thanks to Synaptics starting to mass produce its in-display sensors. Simply Nippon Display (JDI) believes it has a better solution. Rather than hiding the fingerprint sensor backside a display, why not instead make information technology transparent and embed it directly in the drinking glass?

That's exactly what JDI managed to practice and incorporated information technology into the company's Pixel Eyes displays. JDI already builds capacitive touch sensors directly into LCD panels. This new approach to fingerprint reading takes that a footstep further by increasing the sensitivity of the impact sensor to the indicate where information technology tin can detect the recesses and ridges of a fingerprint. So what you effectively finish up with is a transparent touchscreen so sensitive it tin can take a fingerprint reading.

The get-go version of this Pixel Eyes display transparent fingerprint sensor measures 8-by-8mm and is 160-by-160 pixels, and then 508dpi. Although it's already functional, JDI won't beginning shipping it commercially until March 2022. It's sure to be very popular when it does appear as it means smartphones can comprise a completely hidden fingerprint sensor without taking upward any actress space within the casing. JDI also intends to offering larger versions of the sensor.

As the sensor forms part of the glass it has many uses beyond smartphones. JDI sees information technology being used in home security systems and fifty-fifty integrated into credit cards as an extra form of security without adding bulk. It too means there's very footling that can go wrong across the glass being cracked, making information technology extremely durable, particularly on a device such as a smartphone or tablet. We could even see them integrated into our monitors.
