Huawei’s own ultrasonic fingerprint solution revealed

The blogger @digitalgossipstation revealed that Huawei is self-research ultrasonic under-screen fingerprints, not only this, optical under-screen fingerprints and capacitive fingerprints have Huawei self-research algorithm program, R & D capabilities really no words.

Data show that ultrasonic fingerprint recognition is an emerging technology in recent years, when the finger presses the screen, the sensor under the screen to the finger pressing area to launch ultrasonic waves.

When the ultrasonic contact to the fingerprint "ridge" and "valley", was absorbed, penetration, reflection of the degree of difference, will produce different energy echo and be received by the sensor, so as to build a 3D fingerprint image.

The advantages of ultrasonic fingerprint identification technology include: strong penetration, strong resistance to water damage and stain interference, high recognition rate, support for live detection, and high security.

It is understood that most cell phone brands currently use the under-screen fingerprint solution provided by the supply chain, and Huawei will once again be far ahead of other brands by developing its own ultrasonic under-screen fingerprint.

According to officially announced information, Huawei has increased its strong investment in research and development to build the competitiveness of its products and solutions through technological innovation.

From 2021 to 2023, Huawei's R&D investment accounted for more than 20% of the company's revenue in all three years, and in 2023, Huawei's total R&D investment ranked in the top five in the world.
