Flexible OLED Screen Integrated With Qualcomm's 3D Ultrasonic Fingerprint

-
As early as 2018, Qualcomm has launched an ultrasound-based under-screen fingerprint recognition solution, but its initial competitiveness is not as good as that of other manufacturers based on optical solutions. After unremitting efforts, Samsung applied Qualcomm's fingerprint sensing technology to the Galaxy S20 series smartphones that were launched in March this year. The latest news is that the company has also reached cooperation with BOE to popularize the flexible OLED screen integrating its own 3D ultrasonic fingerprint recognition solution.

Qualcomm said on Tuesday that the two companies plan to develop innovative display products that integrate Qualcomm's 3D ultrasonic fingerprint solution, which will help make such products more popular in the industry. As the world's second only to Samsung 's second-largest intelligent machine OLED panel builders, the Chinese company's panel has been Huawei Mate Xs and Moto Razr (2019) and other folding screen smartphone used, in addition to OPPO, Nubia and other mobile phones Manufacturer's equipment. For mobile phone manufacturers, the highly integrated screen fingerprint solution will make it easier and faster to be applied to new products. It is expected that related products will be available for sale in the second half of 2020. Finally, Qualcomm and BOE stated that in addition to mobile phones, they also hope to cover innovative display products in areas such as extended reality (XR) and smart home.

Compared with the optical screen fingerprints currently popular in the market, the ultrasonic fingerprints are significantly more secure. Their fingerprint recognition is at the 3D level, which can identify the grooves on the surface of the fingerprint. Some fake fingerprints cannot deceive ultrasonic recognition. At the same time, ultrasonic recognition does not rely on optical recognition, so it can perform fingerprint recognition in some special environments, such as fingerprint recognition when wet hands are not affected. Qualcomm has provided the latest 3D Sonic Max ultrasonic fingerprint recognition technology in the Snapdragon 865 mobile platform. This technology has a larger recognition area than the previous screen fingerprint technology, which is larger than the usual screen fingerprint recognition area. Almost half of the screen can be covered, which is more convenient in use. In terms of security, it provides simultaneous recognition of two fingers, making it more difficult to crack fingerprints.

  Beijing time October 10 news, according to foreign media reports, the latest research shows that scientists should be able to create a "super magnetic field" on the earth, equivalent to the magnetic field strength of black holes and neutron stars. According to the latest research report by Masakatsu Murakami, an engineer at Osaka University in Japan, and his colleagues, bombarding microtubes with lasers can generate very strong magnetic fields, which will be of great significance for the development of basic physics, materials science and astronomy research. On October 6, this research paper was published in the open access journal "Scientific Reports". Most of the magnetic fields on the earth, even artificial ones, are not particularly strong. Magnetic resonance imaging (MRI) used in hospitals usually produces 1 Tesla (equivalent to 10,000 Gauss). In comparison, the magnetic field generated by the compass needle swinging northward is 0.3-0.5 Gauss, which is the m...

  As for the Linux 5.4 LTS long-term support kernel, it has introduced many new features and improvements to provide first-class hardware support. For example, use zero-copy network to improve network performance, support Btrfs / OCFS2 file system and DTrace, as well as security enhancement and virtualization support for AArch64 (ARM64) platform. UEK Release 6 includes all Cgroup v2 features of Linux 5.4 LTS, a new parallel optimization framework for CPU-intensive work, and kswapd and kexec for verifying the signature of kernel images. In addition, it supports NFS network file transfer, and can treat persistent memory as traditional RAM NVDIMM, NVMe structure/multipath support, pass-through commands, namespace write protection, and asynchronous namespace access improvements. Users who are currently using Oracle 7 major versions can obtain the Update 9 update through the official resource repository, or visit the official website to download the complete ISO installation image of Or...
