In the latest announcement, Lu Weibing said, however, that Redmi's R&D team has overcome this problem and is ready for mass production.

According to Redmi, the company has achieved this success by using infrared in combination with high-transmittance film material, allowing light to pass through the screen and allowing the sensor to read the user's fingerprints. .

BOE has previously stated that they have found a way to place the fingerprint sensor under the LCD screen, but it seems that Redmi will be the first smartphone manufacturer in the world to apply this technology on products. future trade in which the first devices could be the Redmi K30 Pro or the Redmi Note 9.
