Xiaomi has found a fingerprint technology that can be implemented with an LCD display


Under-display fingerprint technology came into the market almost two years ago when Vivo was the first to launch it.

Since then, many mobile phone companies have tried to incorporate this technology into their mobile phones, but no one has yet been able to use this technology with an LCD screen.

This is because when the LCD screen is activated, the light emitted from the backlight mounted on the bottom, the fingerprint sensor becomes active.

Xiaomi’s subsidiary, Redmi’s brand manager, Lu Weibing, confirmed this by releasing a video showing how the technology works with the LCD screen, the Redmi Note 8 pro.

However, there is no definite information about the first phone to be launched with this technology. But The Redmi Note 9 or Redmi K30 Pro is expected to come with this latest technology.

Weibing’s shared post notes there is a behind – the- IR blaster that emits infrared light. The company’s high- film material allows the infrared light to pass through the screen.

At the fingerprint sensor this light is then reflected back, which then gives the phone a fingerprint. The video shows the fingerprint captured on the screen and it looks like a standard fingerprint scanner in-display.

The Redmi Note 8 Pro prototype’s 15-second clip first shows the registration process and then the unlocking process which appears as quick as any other fingerprint scanner in-display.

Up to now, fingerprint technology in-display was only possible with OLED screens, and LCD screen phones needed to have their fingerprint scanners either on the back or on the side. But now, it looks like brand Xiaomi-sub has found a solution to this issue.

This also means that fingerprint tech in-display will hit the more budget friendly phones that have LCD displays.

In the race to make the bezels as slim as possible, manufacturers were talking about creative ways of introducing fingerprint scanners and in-display fingerprint scanners were a step in that direction.

OLED screens offered the ideal medium for this because they were small and light could easily pass through them but this software could not be used by LCD displays, being comparatively thicker.
