Xiaomi Wang Teng: Fingerprint under LCD screen is technically feasible

by:Kimeery     2021-05-28

According to the latest news, the domestic Fushi Technology recently demonstrated an under-screen fingerprint solution for LCD screens, accumulating more than 160 patents for under-screen fingerprints.

According to the news, supply chain manufacturers have solved the problem of LCD capacitive signal interference and demonstrated the demo solution of fingerprints under the LCD screen. It is expected that some manufacturers will have Low-end models use LCD screen fingerprint solutions.

It is reported that Fushi Technology has successfully solved the bottleneck problems of display effect and fingerprint imaging effect through continuous transformation and experimentation of LCD backlight panels and continuous adjustment and improvement of the fingerprint light path scheme. The LCD panel + under-screen fingerprint solution that can clearly see the fingerprint image.

Fushi Technology adopts an algorithm-assisted approach. By adopting the latest deep learning neural network algorithm optimization, it has realized the rapid recognition of fingerprints under the LCD screen. At present, it is known that its fingerprint recognition rate is comparable to traditional capacitive Fingerprints, and the algorithm is still evolving.

According to Xiaomi’s product director Wang Teng,

The fingerprint under the LCD screen is technically feasible, but it is unlikely that there will be a product this year. It will be listed at the end of the year or next year as soon as possible. Conclusion: The flagships released this year will all be LCD for Samsung screens.

In addition, in view of the LCD for Samsung screen elimination after DC dimming, Wang Teng believes that products with a cost of less than 2,000 yuan will be used.

is a modern mobile phone lcd display widely used in cell phone lcd wholesale industry. It also enhances the quality custom lcd screen value of the products.
