1. Pass Samsung's Note 9 screen fingerprint is more expensive than Face ID;
Gathering micro-messages, the Korean Herald quoted industry news on the 22nd that Samsung Display has prepared 3-4 solutions that allow Samsung to embed fingerprint-sensing sensors in the home screen. One of the proposals has entered a phase of careful investigation. It is estimated that the final decision can be made at the end of March. Samsung Display is improving fingerprint scanning technology for Note 9's flexible AMOLED panel. It is estimated that there should be enough time for the technology to reach Samsung's expectations before it is released in late August.
Why does Samsung want to embed a fingerprint sensor in the screen? Analysts point to the difficulty of finding the location of the fingerprint identification module. This should be a big incentive. Note 8: The fingerprint recognition module is placed horizontally on the left side of the dual lens on the back of the phone. This caused great inconvenience. Although the latest Galaxy S9 smartphone installed the fingerprint module under the double lens to solve the problem, it was still placed on the back of the mobile phone. This could not increase the battery space and extend the endurance.
Juss Hong, director of IHS Markit, said that Apple should continue to use 3D facial recognition technology, but Samsung and Huawei will adopt fingerprint recognition technology embedded in the screen. However, due to the complexity of technology, fingerprint sensor technology embedded in the screen , Will be more expensive than Apple's $ 15.2 Face ID technology for each phone.
A director of a biometric solution developer warns that the screen with embedded fingerprint recognition sensors will have a low yield. Most people in the industry believe that there is no possibility of mass production for smartphones using this type of screen.
2. Huawei or Qualcomm will use ultrasonic fingerprinting program;
Gathering micro-messages. According to recent industry news, Huawei’s upcoming flagship new Mate 11 will be equipped with Qualcomm’s ultrasonic fingerprinting solution. Industry and Ophelia who participate in the joint development will also use this to enter the Huawei supply chain. It is reported that the fingerprint recognition function under the screen is expected to become the bright spot of Huawei Mate 11, and it is expected to begin shipments in the end of the third quarter or the fourth quarter of this year.
Undoubtedly, the launch of iPhone X, the first to use 3D-aware face recognition technology, has created a whirlwind in the industry. However, Android-speaking smartphone makers still hold a wait-and-see attitude toward face recognition technology. The main reasons lie in two aspects: On the one hand, Apple’s 3D-aware camera module costs about US$60, which is expensive, and iPhone X’s sales are not satisfactory. On the other hand, due to potential patent infringement of 3D-aware technologies developed by mainland suppliers, Risk, if the mainland mobile phone manufacturers fully import the flagship model, it will bring risks and harm to the mobile phone brand.
As the 3D facial recognition technology remains to be seen, coupled with the 18:9 full screen push, Android mobile phone manufacturers are increasingly favoring fingerprint recognition technology.
Under the screen fingerprint identification, the core difficulty lies in how to hide under the screen, and through the screen to the user's fingerprint for information acquisition and matching recognition, common capacitive fingerprint recognition technology is difficult to do this. And on the current fingerprint identification technology It is said that only ultrasonic fingerprinting and optical fingerprinting are applicable.
Ultrasound fingerprinting
Ultrasonic fingerprint identification technology is a very new identification solution. Among them, representatives of the company are Qualcomm and FPC. It is understood that Qualcomm's ultrasonic fingerprint identification technology has cooperated with touch-control maker Ophelia Optoelectronics and Industry, though it is compared with traditional fingerprint recognition. The module, ultrasonic fingerprint identification module is about 3 times more than the difference, but its module thickness is about 0.44mm, it can penetrate the protective glass with the thickness up to 800μm and the aluminum plate with the thickness up to 650μm, far better than the capacitive module wears. Transparency (about 200~300μm glass).
At the 2017 MWCS exhibition held in Shanghai last year, Vivo demonstrated to the outside world Qualcomm's second-generation ultrasound fingerprinting solution, which has attracted a lot of attention.
Compared to capacitive and optical fingerprint recognition, the advantage of ultrasonic fingerprint recognition is that it does not need to open the hole to completely give way to a full screen, which improves the waterproof and dustproof performance of the mobile phone. The dry humidity of the finger is reduced, and the wet hands can also be unlocked. Mobile phone.
However, there are limitations, as can be seen from vivo demonstration of vivo, ultrasound fingerprint unlocking can only be in a fixed small area, whether it can be expanded to full screen unlocking.
Optical fingerprinting
The principle of optical fingerprint identification technology is to place a finger on an optical lens, illuminate the finger with light velocity, and then reflect it to the sensor for acquisition and recognition. Representative manufacturers include Synaptics and Huiding Technology.
Although the use of optical fingerprint recognition is currently a mature solution, this method is subject to large oil contamination on the surface of the finger and can not be detected by living organisms. Compared to the commonly used capacitive fingerprinting scheme, the theoretical safety is lower. .
It is worth mentioning that, after Vivo launched the mobile phone with fingerprint unlocking technology under the screen, KGI's analyst Guo Minghao pointed out in the latest investment report that Samsung may not use the new generation of products in the Galaxy Note 9 generation. Screen fingerprint technology.
According to Guo Mingyao, there are still many technical difficulties in the under-the-screen fingerprint identification program, such as the screen protection coating and the impact on recognition accuracy in different environments, as well as excessive power consumption. However, Guo Mingyi still has the biometric technology of fingerprint identification under the screen. The future is optimistic. He believes this technology is a must for full-screen handheld devices.
Guo Mingxi said that Samsung’s implementation of the on-screen fingerprint identification solution adds some uncertainty to the final commercial use of this technology. In his view, the fingerprint identification technology under the screen could not achieve large-scale commercial use until the first half of 2019. (proofreading / Xiaoqiu)

4.vivo Han Bo Xiao: Fingerprints under the screen do not hesitate to take risks, not involved in AI chip production;
Sohu Technology/Cui Jiale
We have been engaged in fingerprinting for a long time. It should be the gathering of the strongest suppliers in the world, including the suppliers of the strongest ICs and algorithms in the United States and Taiwan, and the Korean companies providing the best screens. 'March On the 19th, after the release of the world's first mass-market finger print mobile phone X21, Vipor's product managers Han Boxiao and Zhao Dian revealed their views on the phone.
Maybe there are still a lot of people asking, why isn't Samsung, Huawei, or other mobile phone manufacturers, but vivo is the first to introduce a mass-produced screen fingerprint phone?
In Han Boxiao's view, all this stems from the development needs of mobile phone technology and the spirit of vivo courage.
Under the background of the all-round screen popularity, although the face unlocking method has been continuously developed, fingerprint unlocking is still the most common method used by people. 'The fingerprint's habits are not changed yet. It is very convenient and really cool, short-term look. It has always been the only choice for mobile phone unlocking. ' In addition, according to Counterpoint's survey data, the Chinese replacement cycle has reached 22 months, surpassing the world average. Therefore, new innovations that can impress consumers have become many Manufacturers are trying to chase the key.
Every mobile phone manufacturer is in such a context. In the previous many interviews, most of the manufacturers stated that they are watching the development of fingerprint technology under the screen instead of spending more energy to study it. But for all innovations, In fact, only really dare to try to gain technological progress, of course, also have to face many risks.
Because the screen fingerprint technology research and development is not completed by one or two companies, at present, the fingerprint technology under the screen needs to be integrated with the world's top IC suppliers, algorithm providers, and screen manufacturers, and finally fit into a production line in Nanchang, China. 'Every link needs constant debugging', which requires high professionalism in production.
Han Boxiao admits, 'Began to take a lot of risk, our top team has spent two years. Last year, in the absence of production, without mass production projects, in order to allow suppliers to Continue to invest, set the number of ICs between 20,000 and 300,000 in advance. This has been done without passing through and practicing. This is done with the risk of direct scrapping.
'Mass production is also difficult. Until now there is no comparison. Only our family is engaged in it.' However, Han Boxiao revealed that the current production volume has reached a million level, which is a 10-fold increase compared to January. This quantity can fully meet a large number of consumers.
Of course, on this phone, Liu Haiping and vivo's artificial intelligence plan is another big point of view.
Affected by the iPhone X, it has to be said that before the emergence of 100% full screen, special-shaped screens should be the current trend of increasing the proportion of screens. Those who mocked the ugliness of the iPhone every day when the iPhone X was released have now reached an agreement. Consensus. However, compared to Apple's pot lid, the special shape of vivo X21 can only be said to be air bangs. The width of U-shaped groove is much lower than that of iPhone X. The proportion of screens has reached 90.3%. It should be the concept except for vivo. The highest mobile phone outside the machine.
In this regard, Han Boxiao said that there is still room for improvement. 'Currently, the main problem is the cost. If the screen is made of a flexible screen, the chin can be almost removed, but this will increase the cost, and the supply will certainly not keep up. Because Apple accounts for almost all of its production capacity.'
For Liu Haiping's adaptation, Han Boxiao said that basically 50-60 mainstream applications have been adapted so far. 'We expect this month's TOP100 application to be covered. This is our goal. . '
At the conference site, Vivo also released another important breakthrough - Jovi AI Assistant, equipped with Qualcomm Snapdragon multi-core neural network acceleration chip 660AIE, integrating all available multi-core hardware resources for artificial intelligence complex neural computing, with 6GB storage, can provide powerful artificial intelligence computing capabilities, while processing more AI tasks in parallel.
Since it attaches so much importance to AI, many people are wondering when vivo will also integrate hardware and software, and develop their own AI hardware products.
Han Boxiao believes that Vivo will not be involved in AI chips, and it is more to push forward the research and development of artificial intelligence algorithms in the software field. 'AI needs algorithms, but technical support is not something one can complete'. At present, many teams use their own ideas to Writing AI models for AI training, in fact, this process must be completed by the entire industry.
It also stated that Vivo's mid- to long-term goal for artificial intelligence is 3 to 10 years, and the newly launched brand image, Jovi, will also develop toward long-term goals. In the initial stage, Jovi mainly engaged in some assistant work.
5. Qualcomm to Release Snapdragon 845 VR Development Kit Including Tobii Eye Tracking Technology
Qualcomm (Qualcomm) is building a virtual reality (VR) platform development kit using the Snapdragon 845 processor, scheduled for release in the second quarter. According to the Verge report, Qualcomm's new development tools will showcase each of the Snapdragon 845 VR platforms. Special features, including inside-out mobile tracking, also support HTC's Vive Wave platform. The kit comes with a 2,560 x 1,440 WQHD monitor (single-eye resolution of 1,280 x 1,440, update rate of 60Hz). Unlike Microsoft (Microsoft) The inside-out tracking feature of the Windows Mixed Reality helmet or Oculus Santa Cruz prototype, Qualcomm development tools do not include full tracking of the motion controller, but the upcoming Oculus Go helmet all-in-one system (tracking only the head Turning) provides more degrees of freedom. Qualcomm's system does not require Windows Mixed Reality to connect to computers. However, these specifications are not the main selling points of Qualcomm's VR platform. Besides the inside-out tracking, what is most interesting is Two cameras aimed at the wearer’s eyes, using eye tracking technology from Qualcomm partner Tobii, make the user’s eyes a control system and help to expand The effect of foveated rendering. This is the third version of Qualcomm's Snapdragon VR design. Like the old version, it will not be directly sold to consumers in the market, but Qualcomm stated that helmet manufacturers include Lenovo's Mirage Solo and Vive Focus has built-in Snapdragon 835. If Qualcomm is preparing to release Snapdragon 845 platform in the near future, it is speculated that commercial products based on this chip should be available soon. DIGITIMES
