Synaptics' new fingerprint sensor will mean smoother phone screens
A Silicon Valley biometrics company says it has developed a fingerprint sensor that can sit under glass so smartphone screens don't need a cutout or extra button to accommodate the sensor.
The Synaptics FS9100 sensor can sit under a millimeter of glass and still provide accurate fingerprint readings, so it should be easier to integrate one under a display.
At present, most fingerprint sensors have to sit above the glass, necessitating a cutout in the face of the phone or a dedicated button that houses the sensor. That's the case on market-leading handsets like the iPhone 7 and Samsung Galaxy S7.
And while there are some fingerprint sensors that work under glass, that glass needs to be thinner than 1mm, so the glass needs to be shaved in the area of the sensor.
