A Huawei patent for ultrasonic fingerprint identification technological know-how has been not too way back revealed. The patent software program for CN117058725A describes “an ultrasonic fingerprint identification module, an ultrasonic fingerprint identification system and digital gear” that employs piezoelectric layers and stacked circuit substrates to “enhance the accuracy of figuring out fingerprint information.”
The transfer signifies Huawei might maybe be relocating to impediment Goodix, which a number of companies which embody Samsung right now depend upon for ultrasonic fingerprint tech, however is restricted by Qualcomm patents, for each a report in Gizmochina. An in-household ultrasonic fingerprint system would make Huawei significantly much less depending on different producers and positioned to serve the Chinese language business.
In line with the patent software, “in contrast with the optical fingerprint recognition module, the ultrasonic fingerprint recognition module is much extra appropriate for the technical development growth that the transmittance of the present-day monitor is continually minimized,” since “the thickness of the ultrasonic fingerprint recognition module is thinner.”
Nevertheless, whereas Huawei’s ultrasound-primarily primarily based system is likely to be further spatially economical for ever-much more-wafer-thin devices and screens, there are troubles. One is juice: the “penetrating potential of the ultrasonic wave” is presently not enough for positive terminal screens that can lead to distortion, main to inaccuracy. As well as, noise is an problem: “the echo sign has an enormous variety of indicators mirrored by different items, in order that the genuine sign-to-sound ratio (SNR) akin to the present-day fingerprint image is compact, and consequently the ultrasonic fingerprint recognition module are unable to appropriately and efficiently acknowledge fingerprint info.”
That is, surely, a problem – and a fancy challenge the candidates at Huawei intention to resolve.
Within the meantime, the Shenzhen-dependent group has been undeterred by U.S. sanctions and commerce blacklisting over alleged nationwide safety issues, submitting rather more patents than another enterprise within the planet in 2023. In line with Tom’s Elements, Huawei filed for six,494 patents final yr – 2570 additional than Samsung, which got here in at choice 2 with 3,924 filings.
China is the world chief in patent apps, ahead of the U.S., Japan and South Korea.
