Greetings Mi Fans,

Welcome to yet another Tech Wednesday !

Fingerprint-on-displays (FOD) has been a breakthorugh technology since it began. People across the globe have loved they way they could unlock their phones by keepung their fingers on the screen of their smartphones.

Due to the evergrowing love for this tech, OEMs have brought indisplay scanners even to the mid range smartphones. The only con that this tech had till now is that it could be used only on an AMOLED panel as it needs light to pass through it.

But, recently Xiaomi's sub-brand Redmi showcased a working device that has a fingerprint-on-display working on a LCD panel.

Redmi's manager Lu Weibing showcased a Redmi Note 8 Pro device with an indisplay fingerprint scanner. The technology used is an IR blaster behind the screen that emits infrared light.

The high-transmittance film material that the company has used allows the infrared light to pass through the screen. This light is then reflected back at the fingerprint sensor that then gives the phone a fingerprint.

Getting it work on a LCD panel, will enable the reach of this tech to phones under low-mid range or even budget range.
