Redmi implements in-display fingerprint sensor on LCD screen | Report

09 March 2020 0

The in-display fingerprint sensor that has now become a staple in the smartphones using OLED screens is about to take another leap. Redmi General Manager Lu Weibing took to Weibo to announce that the company has managed to implement the in-display fingerprint on an LCD screen, something which wasn’t possible before.

Smartphone makers using LCD screens for their phones have been relying on either rear-mounted or side-mounted fingerprint scanners to offer more display area. But having a more-advanced solution to bezel-free display will simply add richness to the design of the phones that use LCD panels. This means, sooner even the low-end LCD phones will have this caliber to unlock your device when you press a certain area on the screen.

According to Weibing, the tech is already in mass production which means we may see it coming on a Redmi phone using an LCD panel.

The fingerprint sensor sits below the screen and there needs to be a channel to transmit optical or ultrasonic signals. However, on LCD, it wasn’t possible due to the backlight module. But it has now become possible, thanks to the efforts of Redmi.

Weibing via his post briefly explains the working of this new tech. According to Weibing, his R&D team made this tech possible using an infrared high transmittance film material. The transmittance of infrared light that wasn’t previously possible on the LCD panel for scanning the fingerprint, has now received a solution, thanks to the new material used. This new infrared high-transmittance film material improves the transmittance and thus a fingerprint is recorded.

“The infrared transmitter at the bottom of the screen emits infrared light. After this fingerprint is reflected, it penetrates the screen and shines on the fingerprint sensor to complete the fingerprint verifications.”

Well, the tech sounds interesting but can only be experienced when Redmi brings its first phone with this tech.

Meanwhile, Redmi has an event to conduct on March 12 where it will unveil the new Redmi Note 9 series. So, let’s just wait for that and see how it goes.
