Almost every mobile phone manufacturer will mention the term "black technology" when developing a conference. Friends who like Japanese anime must know that the word first came from the light novel of the same name in "All Metal Frenzy". In fact, the original intention is that it is difficult for some people to have ordinary people. Understand the technology of even a little supernatural phenomenon. In order to chase the popular mobile phone manufacturers to give each interesting feature the word is indeed a bit too much, but in fact, the heart of exploring new things is good. In the past few months in 2017, the mobile phone industry has had some new developments this year. Of course, the changes are not as big as expected. After all, due to the development of technology, it is difficult for mobile phones to surpass conceptual growth. However, some content can be foreseen, and mobile phone manufacturers will develop towards a more convenient and more technologically savvy direction. Further attempts to use fingerprints without biometrics Fingerprint recognition, still questioned three years ago, this feature is just getting started, only a few products are willing to use. But soon with the introduction of Apple, Samsung and other international big names, almost no mobile phone manufacturers dare to despise. Now, whether it is a top-grade mobile phone of five or six thousand yuan, or an entry-level mobile phone of five or six hundred yuan, who dares to give up fingerprint recognition? This is undoubtedly a fatal flaw. However, fingerprint recognition is also divided into genre. For example, the front and rear positions have been played before, but the Samsung S8 released not long ago this year is hard to understand. The front-end fingerprint design that has been used all the time has suddenly become What about the rear fingerprint? For Samsung, it doesn't matter whether it is front or rear. If other designs have room for improvement, final fingerprint recognition will make way for it. There is also news that Apple will also give up the Home button used for many years to make a different fingerprint recognition. In any case, the fingerprint recognition module will continue in the mobile phone field for a long time. From the application level, this function has just begun, and the supporting content is not perfect. In theory, there are many places where fingerprint recognition can be used, but now The main thing is to unlock and pay, of course, these are not perfect, and the coverage is not good. After all mobile phones have realized the transition of fingerprint recognition, this year is expected to achieve better application of fingerprint recognition. But ultimately consumers need privacy and security. Fingerprint unlocking is just a means and a tool. Therefore, Samsung has prepared the iris recognition function. We have introduced this iris recognition more than once. His safety performance and unlocking speed are not lost to fingerprints, and it is regarded as the standard for the next generation of biometric recognition. However, considering the problem of different user habits, perhaps the two will coexist to some extent. In fact, in addition to fingerprints, irises and other technologies such as voice recognition, but they have not formed a mainstream, from the point of view of this year, Apple is also expected to bring the first iris recognition mobile phone, and Apple and Samsung's design often become the industry wind vane. I believe that there will be more mobile phone manufacturers to try before the end of the year. OLED screens become mainstream but supply is difficult According to recent news, Apple Apple has already talked with Samsung about the specific cooperation. The latter exclusively supplies the OLED screen required for the iPhone 8. (The assembly of the OLED screen will start in May), and even more enviable is that this screen ratio The Galaxy S8 is a higher end and the display is better. This news really makes Apple fans excited. After all, Samsung's OLED screen is recognized as the best display, but unfortunately the production capacity is limited and the price is relatively high, only a few high-end mobile phones will be used. This time Apple ate 64 million OLED flexible screens at a time, but Samsung may increase production capacity for Apple, but it is hard to say that it can increase to 72 million, which means that Apple will share some of the other mobile phone manufacturers. Capacity resources for OLED screens. In the future, Android mobile phone manufacturers will find it easier to get an OLED screen. Of course, there is no difficulty for those mobile phone brands with guaranteed sales, but the time may not be as guaranteed as before, and there may be a delay than originally planned. But now OLED screen phones are basically no one can rival Samsung, although LG also has OLED screens but the capacity and effect are worse. In addition, Japanese manufacturers have begun to pay attention to OLED screens, but it is difficult to achieve a level of competition within a short period of time. Therefore, this year's OLED screen is still only used on the high-end models of big brands, I am afraid it will not be fully popular, after all, the cost is there. In addition, this year, the mobile phone industry has an interesting design trend or product signs, and the proportion of mobile phone screens is getting higher and higher. In fact, since the beginning of last year, it has paid attention to the screen display. Under the size that the palm can grasp, the screen becomes bigger and bigger. Therefore, the front bezel is getting more and more home, the handset, the Home button, etc. are gradually compressed or even moved to other locations. In short, it is the actual demand of the consumer to maximize the screen size in a limited area, which explains why Samsung will The front home changes to a combination of virtual button + back fingerprint. Dual cameras cover the high end Last year, dual cameras became popular, but not all high-end phones will use dual cameras. For example, iPhone 7 does not. It is only used on the iPhone 7 Plus. Samsung has not used it, but more and more consumers have begun to pay attention. The dual camera, it turns out that Samsung has just tried on the S8 mobile phone just launched this year, because someone exposed the early prototype, there is a dual camera version. Although dual-camera phones are everywhere in the high-end field, and there is even a trend of coverage, is the dual camera really useful? In fact, most of the dual cameras on the market are matched by the main camera + auxiliary camera. The auxiliary camera is a black and white product, which can only play a supporting role. Even if it is completely blocked, it can be used to take normal photos. There will be some impact when the background blur is achieved in the double-camera simulation large aperture, but according to the actual test, the impact is not very large. So there is not much effect in theory, and the large aperture effect of the algorithm + double vision simulation has a good performance in some environments. If the picture structure is too complicated, there will be a BUG. The next picture will show these. problem lies in. There is a clear problem with the blurring in the red circle. Of course, not all programs are useless. Apple can also achieve 2X optical zoom in portrait mode, which is achieved by two different cameras. In theory, this function is much more interesting than the auxiliary camera to achieve large aperture effect. The practicality is also stronger. Perhaps this will be one of the directions for the development of other mobile phone manufacturers. This year OPPO exhibited a 5X optical zoom technology at MWC2017, even surpassing Apple's solution. It is expected that this year's application in OPPO products is expected to be expected. There is no doubt that this year's high-end mobile phones will start to pay attention to the dual camera mix, but for the consumer, only a background blur (not a mature application) and give too much practical use, just the sales gimmick, However, if optical zoom is achieved, it will be more practical. I believe more and more manufacturers will develop this. This year should be said to be a year of mobile phone manufacturers' precipitation and exploration. It is difficult to see particularly big changes in mobile phone products. The previously rumored Samsung X mobile phone has also been confirmed not to be released. It is still unclear what the future mobile phone will be. But these details of the technology may give us some inspiration.
