Xiaomi Obtains Patents for All-Screen Under Display Fingerprint

Gizmochina recently announced that Xiaomi has successfully obtained a patent for its All-Screen Under Display fingerprint technology, according to the China National Patent Database.

What happens next?

Mobile phones with other Under Display Fingerprint technology currently available require the user to place a fingerprint on a specific location on the screen, but with this new technology, the screen can be unlocked by placing a fingerprint anywhere on the screen.

Most of the users can avoid many of the inconveniences of using the Under Display Fingerprint due to the inability to place the fingerprint in the correct position.

How will this process take place?

According to this patent, mainly Infrared LED Light Transmitters and Receivers are used for this purpose. These transmitters and receivers are located between the AMOLED display and the touch screen layer.  In this case, the user puts his finger on the display and the fingerprint is captured by the infrared LED light transmitter through the touch screen layer and then the screen is unlocked after comparison with the data.  Infrared LED Transmitters outside the fingertips do not activate during this process. This minimizes the battery usage of the phone as well as the impact on the eyes of the user.

xiaomi-vs-huawei

Huawei has filed a patent application for All-Screen Under Display Fingerprint technology in 2020 before Xiaomi, but they have not yet released the technology used for it.

With Xiaomi’s move forward this year, many commentators are of the opinion that this technology will probably be used for their future mobile phones.
