Optical Fingerprint Sensors Can Now be Embedded in LCDs
A new technology from 3M will allow optical fingerprint readers to be used behind LCD screens. Until now, optical in-display fingerprint sensors have been limited to OLED displays. Typical LCDs have multiple layers made from thin films that reflect and diffuse light, which would interfere with an optical fingerprint sensor. 3M's new NITS (Near Infrared Transmission System) technology replaces those layers with new films that perform similarly for visible light (retaining at least 97% display brightness when optimized), but are transparent to infrared light. This allows an infrared fingerprint sensor to operate from behind the LCD uninhibited.
