The fingerprint scanner has moved under the display in the pursuit to make room for bigger screens, but with a big caveat - it can only be placed under OLED panels since only this type of display can allow for the light to pass and complete the scan.
Now, a Chinese company called Fortsense, has figured out a way to put the sensor under an LCD, and expect smartphone manufacturers to adopt the tech by the end of the year.
According to leaked photos of a marketing presentation, Fortsense has figured out how to let light pass through the LCD in order for the optical FP scanner to read the actual finger - with a specific membrane, placed between the layers of the screen. That way the sensor can read a finger placed in 160 different ways.
Finding a way for the scanner under the LCD can make a difference in the low-end and middle-range smartphones, which still mostly rely on LCDs.
