Want to change the machine as well as so on | 18 years phone black technology forecast

In the past year, we witnessed the AI ​​AI technology, facial recognition technology, display HDR technology in high-end mobile phone brave attempt; also witnessed the full screen technology, fast charge technology and dual camera technology from high-end products to The process of successful penetration of low-end products, in which more and more people are enjoying new technologies Phone Using the experience brought great improvement.However, a new year has come, what new cell phone technology will be born? And what new technologies will be popularized in the civilian price segment? I hope this article can give you some guidance.

In the following articles, I will in turn introduce you to the new technologies that I consider most likely to be applied to mobile phones in the 18 years and give them the level to look forward to, expressed in ★, 5 ★For the most anticipated, also on behalf of the mobile phone to improve the experience of using a very great help, followed by a ★ said it may not be obvious for us to improve the experience of using the same I will also be new technologies in the mobile phone industry, the scope of popularity ★ number As a measure, you can visualize how far this technology is from us.

No.1 screen fingerprint recognition technology (unlisted)

Worth looking forward to: ★★★★

18 years of popularity: ★★★

After almost four years of market development, fingerprint recognition is now almost standard on smartphones, which not only protects the device, but also unlocks the speed of less than 0.5s. Almost no password can be found. The reason is because fingerprinting is too convenient.However, with the rise and popularization of the concept of full screen last year, the positive fingerprint recognition button design has been frustrated by the large-scale abandonment, because it hindered the expansion of the screen.Other handset manufacturers either fingerprint Identify the regional design in the rear of the fuselage, or directly cancel, switch to other biometric programs, Such as iPhone X. Only a handful of manufacturers still use the only little space to retain the fingerprint keys, such as Huawei Mate 10. People like to unlock the front of the fingerprint, the reason is obvious, the phone is in front of us, vision can help us accurately Finger on the fingerprint recognition area, while the design in the back will reduce people's confidence in the accurate operation, so its design in the fuselage front, universal coverage has been the consensus of the industry.So when the full screen threat poses a positive fingerprint identification , A brand new positive fingerprint recognition technology was born, that is, under the fingerprinting technology.

Under the fingerprinting technology is the fingerprinting design components in the bottom of the screen, when you need to identify the fingerprint, we only need to touch the specified location on the screen can be achieved.Obviously, this is not an easy task, because the traditional Capacitive sensors are used more often in fingerprinting modules, which can function in thinner media, but can be paralyzed if placed under thicker screens, requiring biometric vendors to look for other techniques to identify fingerprints from the bottom of the screen The good news is that there are really such technologies, and depending on the implementation principle, they can be divided into two categories, one is optical fingerprint recognition and the other is ultrasonic fingerprint recognition.

At last year's MWC2017 show, Biometrics, a domestic biometric vendor, demonstrated its own screen-less fingerprint design solution and successfully ported it to the Samsung S7 edge mobile phone. At that time, I witnessed the staff put their finger on that mobile phone Screen, and successfully unlock, and then use my own fingers to complete the same operation can not be unlocked.Remember at that time the staff at the trip told me that this technology uses the principle of optical fingerprint lock, the technology has matured, but when to market Then according to the customer's product to decide.Now, today, but still not a product really available, then I learned that may be due to mass production problems.

The principle of optical fingerprint unlocking is to illuminate the surface of the finger through the screen glow and record the fingerprints through the image sensor at the bottom of the screen in order to achieve the purpose of identification.But this technical principle is only feasible for the screen self-luminous OLED screen, The LCD screen due to structural limitations, and can not use this technology.However, we said earlier, there is another solution, that is, under the ultrasound screen fingerprint recognition technology.Its principle is through the screen below the excitation device to produce a Ultrasound, and then this ultrasound will pass through the screen touches the fingerprint echo, due to the characteristics of the fingerprint uneven, the echo waveform will be different, then another echo below the screen will record these echoes, and eventually calculate the fingerprint Of the features, which also reached the purpose of identifying fingerprints.Moreover, in early November last year, the famous Swedish biometric identification FingerPrint (FPC) company released the ultrasound screen fingerprint recognition scheme can not only be used for OLED screen, the same also applies to LCD screen, so that under-screen fingerprint recognition technology to have a wider use of space. However, ultrasonic fingerprinting has its own limitations. The core problem is that it is difficult to ensure the recognition accuracy is relatively low.

Although each of the above two types of fingerprinting solutions have their own problems, it is clear that those outstanding biometrics companies will not sit idly by to these problems, so we often hear the voice of a mobile phone that will be under-screen fingerprint technology At present, it seems that the biggest momentum is the domestic mobile phone manufacturers vivo. Just yesterday, there is news that vivo X20 Plus UD has obtained 3C certification, is said to be released this month, and UD letters behind its name is the abbreviation Under Display, indicating that it will be equipped with a fingerprint recognition technology under the screen.

There is a characteristic of the new technology of domestic mobile phones, that is, whenever the technology seems to improve the user experience more clearly, then within a few months, this technology may be popular in domestic mobile phones, so we have reason to believe that, In 2018, it will be the first year of screen fingerprint recognition technology. In the first half of this year, there will be a number of high-end mobile phones equipped with this technology. In the second half of the year, as the industry is mature, the technology will gradually penetrate to low-end and mid-range terminals.

No.2: High-power wireless charging technology

Worth looking forward to: ★ ★ ★★

18 years of popularity: ★ ★

Wireless charging is not a new technology, but it is still not popular or regrettable until now.After all, charging is something we have to do almost daily, and for those with severe low Power phobia author, almost as long as the encounter convenient charging environment, it will charge the phone.However, plug the data cable is not only cumbersome operation, the interface and wire loss is inevitable.This is the wireless charging can Solve the problem, we only need to put the phone on the wireless charging base, without any operation of the phone will automatically charge.

If put in the first two years, people complain that the wireless charging market has not yet nurtured, lack of public facilities, resulting in the technology is not popular yet understandable, but now, with Samsung and other manufacturers have followed Apple, home makers, cars Manufacturers, peripherals manufacturers have also introduced a number of products with wireless charging capabilities, so the breath of wireless charging technology has arrived.

According to the principle of wireless charging technology can be divided into electromagnetic induction, magnetic resonance and radio wave. But now the real application in the mobile phone industry and the most mature technology only electromagnetic induction charging technology. So we are familiar with Qi wireless charging standard Is based on this.Currently, the latest Qi1.2 standard wireless charging equipment has been able to achieve 15W of charging power, the parameters have been very close to the current market mainstream 9V2A wired fast charge program, but with more than 20W wired fast charge However, we believe the higher power wireless charging solution will debut as the new standard is set for the new year, and it will be paired with more handsets , While the traditional low-power wireless charging technology may be popular in the low-end machines.

Also worth mentioning is that due to technical principles, wireless charging coil and charging equipment can not be clamped between the metal material, so carry this technology must be non-metallic phone back shell, as we saw last year, many equipped with wireless Charging the flagship aircraft uses glass as the back shell of the same material, is to meet this requirement, so if we assume that this year's wireless charging technology will be universal, then follow the design trend of the metal integrated body for several years will become history.

Also need long-winded is that wireless charging technology seems to be charging interface charging method into the coil for the fuselage charging, but in fact also need to handset with wireless charging control chip to ensure the stability of power supply, and this chip is wireless Charging one of the core technologies, higher technical barriers, which means that the current impact of the popularity of wireless charging technology, another major constraint is the cost.Because China wireless charging manufacturers have successfully developed a set of wireless charging solutions In November last year, Jinli released a high-end flagship M7 Plus, which is equipped with a domestic wireless charging company Yi Chong wireless wireless charging solution produced by the agency test wireless charging power up to 14W, has surpassed Apple's 7.5W. This shows that the domestic wireless charging technology has matured, and cost issues in the domestic manufacturers involved, will be a problem!

No.3: super fast charge

Worth looking forward to: ★★★★★

18 years universal coverage: ★

A classic advertising slogan 'charge 5 minutes, talk for two hours' so that fast charge technology is widely known. Now people complain about the phone one day a charge has complained of numbness, while lithium battery technology is also as stagnant as the national football as frustrating, but if the charge Can be faster, then hurry up, it will be greatly comfort to users, and many related companies are indeed dedicated to this.

On February 23, 2016, when I went to Spain to cover MWC (World Correspondence Show), OPPO showed off its latest black technology, the OPPO VOOC Super Flash Charger, which can fill a 2500 mAh cell phone in 15 minutes, Charging 5 minutes, call 10 hours, and in the field had a charging demo.However, today, I wait for the sublimation of lily, but still did not see the product equipped with this technology appears.Individually, last year's MWC At the show, the Meizu booth also showed the same super-fast charge technology - Super mCharge, which can fully recharge a 3000 mAh battery in 20 minutes and once again lit the light of hope in my heart. However, another year passed. ...

In 2015, Huawei Watt Labs demonstrated the fast charge technology results of 48% charge of a 3000mAh battery for 5 minutes at the Japan Battery Conference. At the end of the year, the glory brand of Huawei released the Magic Magic phone, and the charging scheme of this device was met The staggering 40W charging power and a 5V 8A low-voltage quick-charge solution help to control the heat and maintain a relatively stable high-power charge. Although the actual charging speed is not as exaggerated at the battery assembly, 15 minutes To reach more than half of the 2900mAh battery power is still staggering, and this phone was later successfully sold. However, since this model, Huawei will no longer have such a fast charging capacity models. Even now The top Mate 10 Pro flagship phone is also equipped with a 5V 4.5A 22.5W fast charge technology.I presumably because of the cost and production difficulties led to 40W fast charge in the pan, but after all, Magic Magic is a mass production The product, it represents us from the real super fast charge and one step closer!

At this point, we can see that the industry attaches great importance to the super fast charge capacity of mobile phones, and have the corresponding technical reserves, but due to some outsiders inconvenience to know, these technologies are still far from the general public for some distance. I can see the super fast charge technology amazing charging capacity, I am conservative, but I believe that day will come sooner or later.

No.4: SLP motherboard stacking technology

Worth looking forward to: ★★★★

18 years universal coverage: ★

Carefully users will find each text theme I will use a specific color to mark, and for the SLP motherboard stacking technology I choose the color is black, because I think it is enough black technology. What is the SLP motherboard stacking technology? In fact, is Will be more than one motherboard stacked together, and through the advanced welding process of the two motherboards corresponding to the number of pins welded together, so that the two motherboards circuit interlinked, as if the frame is a number of straight ladder multi-storey building. The technology itself, in fact, the difficulty is not high, and has applications in other industries, but in the mobile phone industry, its difficulty lies in how to design circuits and cell phone structure to meet the thicker than the conventional motherboard.

Last year, Samsung came out with its own products using SLP stacked motherboard, but let the iPhone X pre-empted, it is estimated that the forthcoming Samsung S9 will be equipped with this technology. So why is it so favored by the international manufacturers? In fact We look at the internal structure of the iPhone X is not difficult to understand.

Within the iPhone X, the motherboard takes up almost the smallest area of ​​the iPhone, but even at a fraction of the time it does not shrink, and smaller motherboards make room for more battery power The machine's battery capacity larger than its larger iPhone 8 plus even larger.Seeing the charm of SLP technology, it can greatly reduce the footprint of the motherboard, leaving the battery considerable space.

As mentioned earlier, the complexity of circuit design and handset design is one of the major issues that constrain the development of the technology. Another problem is that the chips are stacked together. Without good system power control, the heat builds up Being unable to spread will be an equally daunting issue, especially for Android phones.

No.5: 5G

Worth looking forward to: ★

18 years universal coverage: ★

The essence of 5G technology is still based on the mobile Internet, but the huge increase in transmission speed and very low latency have brought qualitative changes to the 4G applications that we are accustomed to today. For example, broadband will not be installed in the future because we only Need a router capable of receiving 5G signals can enjoy comparable to fiber speed anytime, anywhere; we do not need a computer, only need to have access to a 5G monitor will be able to access the operator cloud computing platform for high performance; ultra-high definition video The meeting will be as common as calling; on the plane, you just need to smoke a kung fu, a 4K ultra-high definition Blu-ray movies can be downloaded on the phone is finished .......

The future is good, but it is only for people to look forward to. The current 5G standard is just the initial stage of the establishment, and really put into commercial use at least until 2020, even if this is only the beginning of qualitative change, related industries Development requires a very long process, which means that today even if we have 5G of hardware, it can play no more than the 4G handsets in hand.

No.6: Flexible package screen

Worth looking forward to: ★★★★

18 years of popularity: ★ ★

Charm blue president Li Nan was published last year, "Do not fight well, Samsung S8 is" full screen "article mentions that currently on the market in full screen mobile phones are not counted, only Samsung S8 screen because of the COF flexible packaging technology can be called "So full screen." So what is the COF flexible packaging technology? Briefly, the original is from the bottom of the screen out of the old can not display content folded to the back of the screen, so that the bottom of the screen is not cable Block, the screen can be designed closer to the border.

As far as I know, iPhone X's screen to do more thorough it with the bottom part of the screen with a part of the display area bent to the back of the screen, so that as long as the screen close enough to the border that it becomes a borderless screen yet? Because of this design, it's four sides of the frame planing bangs area, the other parts are ultra-narrow design, so as to achieve the closest full screen effect.This design I really think it is very black technology.

iPhone X's screen was originally supplied by Samsung, LG also joined the late supply chain, I believe in the flagship camp in 2018, will see more like iPhone X this screen design, but because of OLED screen production capacity constraints, With this design of the model will not be too much.As for the low-end market, may still remain in the 18: 9 is a full screen of the vicious circle .......

No.7: waterproof

Worth looking forward to: ★ ★ ★

18 years of popularity: ★ ★

First mention of waterproof, I believe we first think of it is Sony, the earliest consumer-grade waterproof phone manufacturers. Let it adhere to the main reason waterproof phone I think because cell phones as people inseparable from the electronic products, will inevitably encounter in the next Rainy days, seaside, pool side of the scene, and these scenes once the phone accidentally fell into the water, the traditional cell phone technology, it is bound to short-circuit mobile phone wasted, and if it is waterproof, then you can eliminate this scenario Concerns, this is the meaning of waterproof handsets.

I have also disassembled a lot of waterproof phone models, and Sony, Samsung, Apple, and even the Lord to do the three defenses are included, give me the feeling that the waterproof design of the open part of the sealing design more High requirements, the speaker, the earpiece in the water problem with the details of the design requirements for some manpower can not be achieved by the mounting process has certain technical requirements, these requirements alone are not very difficult to achieve, but need On the materials, assembly process, equipment tolerances are strictly control.Some instances are weaker in the industry chain in the small talk of manufacturers will be difficult to control these places are in place, so I think the waterproof features in 2018, Will still only high-end machine dare to play.

Full text summary:

So far, I have summarized for everyone 7 new technologies that I think will be the trend of mobile phones in 2018. If you are an ordinary consumer, I suggest you buy mobile phones in mid or late period, because that time will be big Part of the flagship technology decentralization, new technology updates iteration completed node, you will get with great mobile experience.
