Huawei's self-developed ultrasonic fingerprint solution revealed: once again far ahead of its competitors

According to news on March 15, blogger Digital Chat Station revealed that Huawei is developing its own ultrasonic under-screen fingerprints. Not only that, optical under-screen fingerprints and capacitive fingerprints both have Huawei’s self-developed algorithm solutions. The research and development capabilities are really nothing to say. .

Data shows that ultrasonic fingerprint recognition is an emerging technology in recent years. When a finger presses the screen, the sensor under the screen emits ultrasonic waves to the area where the finger is pressed.

When ultrasonic waves come into contact with the "ridges" and "valleys" of fingerprints, they are absorbed, penetrated, and reflected to varying degrees. Echoes of different energies will be generated and received by the sensor, thereby constructing a 3D fingerprint. image.

The advantages of ultrasonic fingerprint recognition technology include: strong penetration, strong resistance to water stains and stains, high recognition rate, support for living body detection, and high security.

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

According to official information, Huawei has increased its investment in research and development and built 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 each of the past three years. In 2023, Huawei's total R&D investment ranked among the top five in the world.
