The scanner is built directly into the screen. JDI (Japan Display Incoporated), a company known primarily for displays, has announced its first fingerprint scanner, which can be used in many types of devices.
Based on the capacitive technique, the new JDI scanner is transparent and can be integrated in the screens of future smartphones. Traditional fingerprint scanners are based on silicon, and one thing you can not say about them is that they reveal something through them. Recently, solutions have appeared to allow fingerprint scanners to be placed under screens, but the JDI approach is different.
JDI uses its own Pixel Eyes technique, thanks to which the capacitive sensor is placed directly in the displays. The company managed to improve the sensitivity of this solution so that the scanner can detect the fingerprints of our fingers. Everything is embedded in the screen glass and is highly transparent, so it does not cover the image.
In its current form, the JDI scanner has dimensions of 8 x 8 mm (160 x 160 pixels at 508 pixels per inch), and the manufacturer is already planning to launch deliveries in March next year. JDI also provides for the creation of larger and smaller scanners than the one announced, and in the future also the integration of this solution in flexible screens
