Redmi showcases under LCD fingerprint scanner
- Xiaomi’s bub-brand Redmi has successfully found a way to make an in-display fingerprint scanner work under an LCD display. The demo video has been embedded at the end of this article.
- The company has demonstrated this technology under a Redmi Note 8 Pro prototype. However, it looks like its too late for this technology to be implemented in the Redmi Note 9 series, which will be revealed on March 12.
- The in-display optical fingerprint scanner was first invented by Vivo in early 2018, and this tech has become quite mainstream ever since. However, this tech only works with OLED displays, since the backlight module in LCD displays interfere with the sensor.
- Redmi, however, claims that this issue has been overcome with its new infrared high-transmittance film material, which is claimed to let the sensor see the finger.
- With this invention, Redmi will be able to use in-display fingerprint scanners in more affordable smartphones – which use LCD displays – since OLED displays turn out to be too expensive for these phones.
