Redmi Successfully Implements Fingerprint Sensor Under LCD Display

So far, in-display fingerprint scanner technology has been only made available on phones with OLED panels. Redmi General Manager Lu Weibing took to Weibo to confirm that Redmi has successfully implement in-display fingerprint sensor on an LCD screen. It appears that a high-end Redmi phone with LCD screen arriving in the near future will be equipped with the new technology.

LCD screen phones that have launched in the past have either featured rear-facing fingerprint scanners or side-mounted fingerprint sensors. Weibing reveals that Redmi’s R&D department has not only successfully tested LCD panel in-display fingerprint scanner, but also it is now ready for mass production.

Weibing explains that the innovative usage of infrared high-transmittance film material greatly improves the transmittance of infrared light could previously could not pass through the LCD panel for scanning the fingerprint. The new technology features infrared transmitter at the bottom of the display through which infrared light gets emitted.

It penetrates the display and glows on the fingerprint senor to complete the fingerprint verification. Shown above is the demonstration video which showcases the all new LCD panel’s in-screen fingerprint reader.

There is no word on the first Redmi phone that will be arriving with the new technology. Redmi India will be announcing the Redmi Note 9 series on March 12. It is said to include three models such as Redmi Note 9, Redmi Note 9 Pro and Redmi Note 9 Pro Max. None of these phones will sport in-display fingerprint reader technology.
