A few years ago, when we were shopping for smart phones, the most important thing was the hardware indicators such as processor, memory size, camera parameters, and even the situation of “only running the heroâ€. However, in recent years, this situation seems to have changed, manufacturers have begun to pay more attention to some innovative features, such as dual camera, face recognition, wireless charging and so on.
There is no doubt that these innovations are the driving force behind the new smartphone industry.
At present, many manufacturers have begun to look at the future and start research and development innovation. We have also seen the birth of many new technologies. Let's take a look at some of the cutting-edge innovations that may change the smart phone industry in the future.
Flexible folding display
To say that the most popular cutting-edge technology in the smartphone industry is the non-folding screen. Recently, news about Samsung's launch of its first folding screen smartphone at the end of this year or early next year is endless. In addition to Samsung, including LG, Lenovo has also demonstrated the technical prototype of the screen can be folded or bent. ZTE has even launched a folding smartphone called Axon M. Although this product is not really a folding screen, at least let us see a trend in the future of the smartphone industry.
The most direct and obvious benefit of a collapsible smartphone is the dramatic increase in the screen size of a smartphone. Conversely, it is also possible to significantly reduce the size of the tablet and increase portability. It can be said that this technology can integrate tablets and smartphones in the future, making the boundaries of both sides more and more blurred.
But for foldable screen smartphones, there are still many problems to face. From the hardware point of view, the folding of the screen is only the beginning. In the future, more hardware parts such as battery, motherboard and body also need flexible characteristics. In addition, from the software point of view, the system should also adapt to the operating space of the screen under different sizes. At present, neither the hardware nor the system is ready.
Screen camera technology
The full screen seems to have become the trend of the development of smart phones, and the comprehensive screen has a qualitative improvement compared with the ordinary screen design style, both in terms of visual space and visual effects.
However, almost all manufacturers have not solved the problem of the position of the full-screen body components. Whether it is Apple's iPhone X's "Qi Liuhai" screen or Samsung's Infinity Display, everyone seems to have reserved some borders to make room for the components. . At present, the fingerprint recognition sensor technology has appeared on the screen. The following needs to embed the camera below the screen to truly realize the effect of the full screen.
Sony, which has long been known for its black technology, now gives its own answer, which is the screen camera module technology. According to the information disclosed by the industry on Weibo, Sony Semiconductor has developed a screen camera solution, and Samsung has already produced a finished OLED panel in compliance with the requirements, so the future full screen mobile phone will be able to completely remove the forehead, supplemented by the screen. The fingerprint unlocking technology enables a true full screen design.
According to the industry's breaking news on Weibo, Sony Semiconductor has abandoned the development of the corner camera module and changed to the screen camera module technology, which requires the use of a single-sided OLED display with a transparent substrate. Although only two of the industry's OLED panels are available, Samsung has already produced finished products.
At the same time, in response to comments from users, the industry also said that the Samsung OLED display originally had a transparent base, and just Sony can make a screen camera solution, so the two hit it off, in the OLED display-based screen camera solution The program is progressing very fast.
Graphene battery
Smartphones are rapidly evolving in design, functionality, and technology, but one parameter hasn't changed much over the years. That's right, it's the battery. The use of mobile phones has been shortened from the first week to two or three days, until now one day or even half a day. It can be said that the backwardness of battery technology has seriously dragged down the development of the smart phone industry.
As a result, many organizations and companies have begun to focus on developing new battery technologies, with graphene battery technology being the most sought after. The so-called graphene battery is a new energy battery developed by utilizing the characteristic that lithium ions rapidly shuttle between the graphene surface and the electrode. As the newest nanomaterial that is the thinnest, hardest, and most conductive and thermally conductive, the concept of graphene has been receiving much attention since its inception in 2004.
Taking the field of power battery as an example, graphene is a positive and negative electrode material for lithium ion batteries with good application prospects. At the same time, the graphene polymer material battery weighs only 50% of the traditional battery, and the cost will be 77% lower than the lithium battery. From the performance point of view, the graphene lithium battery is charged once and takes less than 10 minutes.
At present, Samsung Research Institute has found a method to combine graphene and silicon dioxide on a large scale. The material to be fused is called "graphene sphere" and has a structure similar to popcorn. The researchers pointed out that this technology not only improves the stability of the battery, but also improves the conductivity, "significantly improves the cycleability and fast charging ability of the cathode."
In addition, domestic media reported that Zhejiang University scientists have recently developed a new type of aluminum-graphene battery using graphene film as a positive electrode material. This battery has an extremely long life, can be fully charged in a very short time, and can work normally in the temperature range of minus 40 degrees Celsius to 120 degrees Celsius.
Mobile phone zoom lens
Nowadays, smartphones are becoming more and more powerful. From the initial simple 1 megapixel camera to today's dual cameras, school anti-shake, phase detection and even iris, smart phones have become the only people. Photographing tool.
However, the development of smart phone camera technology to today, there is still a function is not fully realized, that is, optical zoom, most of them just stay in the stage of digital zoom. The optical zoom of the camera relies on the optical lens structure to achieve zooming, that is, the lens of the camera is moved to enlarge and reduce the subject to be photographed, and the larger the optical zoom magnification, the more distant the scene can be photographed. The digital zoom is actually an electronic zoom of the picture, which magnifies a part of the pixels on the original sensor to the whole picture.
At present, the design of the smart phone body is getting thinner and thinner. Therefore, due to the limitations of its own conditions, it is almost impossible to achieve a good effect of optical zoom. Even if some of the touched optical zoom is realized, the price of the camera protrudes.
Therefore, how to solve the contradiction between optical zoom and the thickness of the smartphone body has become a cutting-edge technology in the smart phone industry.
Long-distance wireless charging
Wireless charging has become a standard feature of many flagship models. From iPhone X, iPhone 8 to Samsung Galaxy S8, Galaxy Note 8, the addition of wireless charging function allows us to get rid of the constraints of cables and charge smartphones anytime, anywhere. To some extent, it also solves the problem of short battery life.
However, the current wireless charging technology is limited to the contact type wireless charging base, that is, magnetic resonance or magnetic induction technology, so in fact, it is not much different from the ordinary wired charging, and still has to be fixed in a certain range to be used. In the future, wireless charging technology can directly extend the effective charging range to the entire room. As long as we enter a certain room, we can start wireless charging.
The new technology represented by uBeam can achieve the above mentioned effects. uBeam's idea is to use ultrasound as a medium, first plug the transmitter into the socket. The transmitter converts the electrical energy into ultrasound, and then attaches a mobile phone case to the mobile phone to receive the ultrasonic signal. When you walk around the room with your phone, uBeam's transmitter can position the moving receiver to ensure maximum energy transfer. The phone case converts the received ultrasound into electrical energy to charge the phone. The whole process is similar to Wi-Fi, but they use ultrasound.
uBeam said that their current charging speed is comparable to the data line. After testing, the transmission distance of ultrasonic wireless charging can be at least 5 meters, and the actual range is much larger. This means that you only need to use the phone properly in the room, and then the battery is always charging. At the same time, in terms of security, uBeam's technology will not generate radiation, and at the same time, like the data line, in addition to transmitting power, it can also be used to transmit data.
