As we all know, mobile phones are evolving in the direction of higher display ratio. At present, whether it is from the interactive experience or from the visual sense, the fingerprint solution that integrates fingerprint recognition into the screen can be better. Adapt to the full screen, that is, by directly pressing the screen to achieve fingerprint recognition and unlocking, encryption and other functions.
The mobile phone China Alliance Secretary-General Lao Yan introduced that the fingerprint recognition of the vivo screen should be the plan of Huiding Technology (98.790, 3.84, 4.04%). At present, the prototype should be able to do the demonstration, but the mass production is not so fast.
Mass production to be brokenIn terms of fingerprint recognition, in 2011, Motorola Atrix 4G already has fingerprint recognition and unlocking function, but due to technical limitations at the time, the recognition success rate is not satisfactory. In 2013, when Apple added Touch ID fingerprint recognition on the iPhone 5S, Android vendors followed suit. As far as domestic manufacturers are concerned, fingerprint recognition has become popular since the Mate7 mobile phone launched by Huawei in September 2014.
With the opening of the full screen era, the design of independent physical buttons or virtual buttons in the traditional scheme will be gradually replaced, so more and more manufacturers are paying attention to how to implement fingerprint recognition under the touch screen.
At present, many manufacturers such as Apple, Samsung, vivo, Huawei, etc. are developing fingerprint recognition technology under the screen. After all, in the mobile phone industry with serious homogenization and fierce competition, the company has taken the lead in launching mature full-screen products for its own technical strength and product differences. It is a kind of evidence.
Luo Zhongsheng, CEO of Foxconn Sharp/InFocus Mobile Division, pointed out that the comprehensive screen mobile phone will bring about the transformation of the supply chain, which is reflected in the design of the comprehensive screen glass, the miniaturization of the camera, the miniaturization of the earpiece, and the design of new fingerprint chips. .
At the moment, Apple is still the leader. The much-watched Apple iPhone 8 can basically confirm the use of screen fingerprint recognition. Due to its strict confidentiality policy, little is known about this. On the other hand, according to supply chain news, Samsung is also developing a screen fingerprint module, but currently it has encountered uneven brightness. Simply put, the area of ​​the fingerprint recognition screen is brighter than other areas, and the optimization of this problem is a long process.
Therefore, Samsung's flagship Note 8, which is facing new Apple products, may not be equipped with on-screen fingerprint recognition. If the rumors are true, it means that Apple can seize the opportunity. It should be pointed out that the full screen does not necessarily use the in-screen fingerprint scheme. Samsung's latest Galaxy S8 put fingerprint recognition next to the rear camera, which of course led to a variety of spit and discussion about the location of future fingerprints.
Laojiao analyzed the 21st Century Business Herald reporter that the scheme of placing the fingerprint under the glass cover can only be used for the AMOLED screen, and the LCD screen cannot be used. The main problem at present is that the noise is too loud. Apple is the most advanced, using the technology provided by AuthenTec acquired five years ago. At present, the mass production of the iPhone8 is already a certain news. According to Apple's style of preparing sufficient inventory in advance, it will be produced three months ahead of schedule and has entered the mass production stage. And several other mass productions will be a few months later than Apple.
The maturity of the supply chain will affect the progress of the full screen mobile phone. It is widely expected in the industry that the full screen will be popularized in various flagship machines in the second half of this year. In the middle of 2018, the technology in the screen will be stable, and then the full-screen mobile phone will become the mainstream.
Manufacturers prepare for warAt present, the mainstream fingerprint identification solution providers in the mobile phone industry mainly include American companies AuthenTec and SynapTIcs, Swedish manufacturer Fingerprint Cards (FPC) and China Huiding Technology.
In fact, in February of this year, Huiding Technology released the fingerprint recognition technology in the display on MWC 2018. Its founder Zhang Fan pointed out that the comprehensive screen will be the next round of mobile phone competition hotspots. The full screen fingerprint recognition will be placed on the front instead of the back, and the mobile phone will become more integrated.
Huiding Technology told 21st Century Business Herald that the key technical problems of fingerprints in the screen are not obstacles, but the large-scale and efficient large-scale production of new technologies involves the cooperation with the display screen, and the assembly process and production yield control are still large. Work to do. The company is confident that this technology will be pushed to commercial scale, but it will take time.
Zhang Fan said at MWC that the optical fingerprint has been done for more than two years, and the show was taken because it is very close to mass production.
With the rise of domestic mobile phones, the first quarter of this year, Huiding Technology has surpassed FPC to become the largest fingerprint IC provider in the global Android camp. According to the financial reports of the two parties, Huiding Technology's revenue in the first quarter was 731 million yuan, a year-on-year increase of 90.21%, net profit reached 175 million, an increase of 150.04%; FPC revenue was about 536 million yuan, a 54% decrease over the same period last year. It was down 88% year-on-year, or about RMB 42 million.
Of course, FPC is not idle, and it is said that they are developing a technical solution that can unlock and identify anywhere on the screen. SynapTIcs also said at the Taipei Computer Show that the first on-screen optical fingerprint sensor is expected to be mass-produced by the end of this year.
Of course, in the face of the saturation of the smart phone market, the “leftovers†in the field of fingerprint identification are also opening up new markets. Huiding is aiming at the PC and more human-computer interaction portals. Since 2016, Huiding Technology's fingerprint chip has expanded into the PC field. Huawei's latest MateBook and ASUS's new ZenBook Flip S flagship notebooks all use the fingerprint solution of Huiding. In addition, Huiding is also developing products for the automotive environment and chips that continuously detect heart rate.
SynapTIcs announced on June 12 that it signed a definitive agreement to acquire Conexant Systems, a provider of smart home voice and audio processing solutions, and announced a definitive agreement to acquire video and audio application processing technology provider Marvell's multimedia solutions division. . SynapTIcs hopes to extend its advantages in mobile phones and tablets to the consumer Internet of Things.
Of course, for fingerprint manufacturers, shipments in emerging areas are still negligible compared to mobile phones, and the mobile phone market is still the biggest battlefield.
We all know that curved-edge phones look good, but they are not easy to protect. In order to prevent the mobile phone from being scratched, current mobile phone users like to stick a phone Screen Protector on the mobile phone screen.
With the development of the market, more and more users like mobile phones with curved screens. Unlike flat mobile phones, the screen protectors of curved screen mobile phones are not easy to buy or stick. The main reason is that the Tempered Glass Screen Protector of curved mobile phones is difficult to fit the height of the mobile phone screen. Then our TUOLI Uv Screen Protector is the best choice for full screen users.
Using the curing principle of the 30 UV lamp beads of the UV Curing Machine to scan the entire screen, the UV Screen Protection Film has the texture of tempered glass. The upper limit of the high temperature of the UV Machine is 60 degrees, has a good heat dissipation function, and has a time setting: 180 seconds. Exquisite and easy to operate, it can make the Screen Protective Film have high light transmittance and smoothness.
