From AnandTech: Synaptics this week introduced its first Clear ID FS9500 in-display optical sensor that can be installed under the surface of an OLED screen. The fingerprint reader works faster than facial recognition and can be used in any environments, including dark rooms and sunny beaches, Synaptics says. The first smartphones featuring the technology are due in Q1 2018.
Biometric authentication has become a mandated feature of every smartphone in the recent years, but integrating fingerprint sensor has become a challenge as screen-to-body ratio is growing and many front panels have no space for the reader. Some smartphone makers install fingerprint sensor on the back panels of their devices, other, like Apple, introduce facial recognition technologies that require IR and RGB sensors accompanied by appropriate processing resources. Synaptics argues that fingerprint sensors on the back are uncomfortable to use, whereas facial recognition technologies are relatively slow and can be fooled. By contrast, Synaptics’ latest Clear ID FS9500 sensor is hidden under the screen on the front and it works as fast as users come to expect from similar devices in the recent years.
