Although the phrase 'smartphone homogenization' is not new, it has been particularly noticeable in the past two years. With the increasingly transparent upstream supply chain and the paralysis of some component technology ceilings, the mobile phone circle has gradually become Bored. In the market of consumer upgrades, self-sufficiency means chronic suicide. Data from Counterpoint shows that the per-user change cycle has increased from 18 months in 2016 to 22 months in 2017, which has also created the Chinese mobile phone market. In the face of this situation, innovation is the only antidote. In the Chinese smartphone brand that has undergone a round of reshuffle, it needs to use more extreme technology and higher-end products to stimulate users. Open the territory to expand the soil. Before the arrival of the next round of 5G vents, guarantee a place on the 'brand table'.
Huawei three photos: domestic mobile phone slaughter DxO
Huawei has been working on photography for many years. Since the P9 series and the Leica branded professional dual-camera mobile phone in 2016, it has gradually emerged as the first echelon of Android. On March 27th, the Grand Palace in Paris, Huawei launched the flagship new machine P20 Pro. Equipped with an unprecedented three-shot, from top to bottom, 8 million pixels f / 2.4 aperture telephoto lens, 40 million pixel f / 1.8 aperture color main lens, 20 million pixel f / 1.6 aperture black and white lens.
Compared with the previous flagship mobile phones, the dual camera solution is divided into two types: Huawei's previous color + black and white dual camera can bring more accurate color to the imaging, better details, Apple and other telephoto + wide angle dual camera can The ability to obtain lossless zoom. Huawei's three-camera solution has achieved both types of dual-camera. By combining the three-camera algorithm to achieve high-definition five-fold three-shot zoom, the Huawei P20 Pro can be easily located in the distance. Zoom in and take a high-definition telephoto photo.
In terms of the main camera, Huawei P20 Pro is directly upgraded to 1/1.7-inch large size 40 million pixels. Select this 'bottom' sensor to increase its own light input, improve the capture speed, and capture a lot of light with black and white camera. Information, effectively improve the details of the picture, so Huawei P20 Pro does not have the problem of poor image quality in most mobile phones in the dark environment, making it easier to capture and greatly improve the clarity of the photo.
P20 Pro's Lycra three photos have also been well received by domestic and foreign media and users. The authoritative video equipment evaluation website DxoMark gave Huawei P20 Pro a high score of 109 points. It has been the top scorer for more than four months and cannot be surpassed. And in
Full screen built by mechanical structure
Since last year, the 'full screen' mobile phone has become a hot new favorite in the mobile phone industry. There are several different forms of 'full screen' mobile phones on the market. However, due to technical limitations at the time, 'forehead', 'chin' and 'bang' Full screen phones are not so 'wide', even Apple has not solved this problem.
Surprisingly, only for half a year, OPPO and vivo took the lead in using mechanical solutions to eliminate 'Liu Hai', integrating front lens, earpiece, light sensor, and even 3D structured light into the mechanical structure. 'The screen space. Both also use the mechanical structure, but the specific implementation is different.
Vivo NEX continues the design of the previous concept machine APEX, hiding the front lens into the lifting mechanical structure. In the self-timer mode, video call and other scenarios, the front lens will rise, and will automatically drop the return position when not in use. In addition, vivo NEX guarantees the integrity of the front screen through full-screen sound technology and hidden sensor applications.
OPPO Find X uses a two-track periscope mechanical structure, which integrates a front lens, two rear lenses, a floodlight sensor, a distance sensor, a dot matrix light projection and receiver, etc. Just like a mobile phone. Incorporating a slide cover, when the system calls the device in the mechanical structure, it will automatically rise. When it is not used, it will automatically close. Therefore, in addition to taking pictures, it is also responsible for 3D structure light unlocking and face payment.
Although technically, they are not necessarily the direction of future interaction, but at the present stage is the best solution, so brave innovation deserves our respect.
The sci-fi feeling is full. The fingerprint is unlocked under the screen.
The fingerprints on the screen make people feel very sci-fi, and at this stage is also a good way to achieve full screen. In fact, many mobile phone manufacturers have tried the fingerprint under the water screen, but why are they gone?
Ultrasonic fingerprint is based on the characteristics of strong ultrasonic penetration. The fingerprint recognition is placed inside the 1.2mm OLED screen. The positive and negative voltage effects are used to generate and receive ultrasonic signals. The signals penetrate the OLED screen and form different peaks and troughs. The intensity of the reflection, generating a fingerprint image, realizes the function of fingerprint recognition under the screen. Compared with the optical fingerprint, the ultrasonic fingerprint has advantages in waterproof and anti-ambient light interference.
At present, there are two main technologies for mainstream fingerprint recognition: optical and ultrasonic. The optical fingerprint sensor illuminates the fingerprint through the light of the AMOLED panel, and then passes through the returned light to the CIS under the screen, and then Then, the return light is analyzed, and the software algorithm is used to realize fingerprint recognition. The disadvantage is that when the screen brightness is insufficient, or there is other display image interference in the fingerprint area, the fingerprint recognition will be wrong. And, in the state of completely black screen, To unlock, you need to wake up the screen first. Optical technology has not yet been mass-produced.
However, there are still some problems in the recognition rate, and the cost of the ultrasonic fingerprint recognition module is relatively high, and there is no good response in the market. In addition, the application of ultrasonic fingerprint recognition to the screen requires penetration of a higher thickness, so this is currently Technology can only be used on OLED screens, because LCD panels require backlighting, module thickness is thicker, and ultrasonic signal penetration is limited. Fingerprint recognition under ultrasonic screen is active sensing, and power consumption is relatively high, if continuous operation is required. The power consumption will be higher. And the fingerprint recognition module under the ultrasonic screen is attached to the OLED panel. If the yield is not good, the OLED panel will be scrapped, the mass production is difficult, and the demand for yield is higher. The merchant is a big test.
And vivo has not given up on the fingerprint under the screen, and its results are also gradual. From the vivo X20 Plus UD on the screen to unlock a single-point screen fingerprint limited to a specific location, to a month after the release of vivo APEX The full-screen concept machine uses half-screen fingerprints, which can be said to be another revolutionary evolution of mobile phone fingerprint recognition technology. In the future, the final form of screen fingerprints should be full-screen fingerprint unlock technology, fingerprints can be entered in any area of the screen. Unlock, I believe it will be realized in the near future.
More accurate facial recognition 3D structured light
Although Apple has already launched 3D structured light last year, it is also included in the first half of 2018. It is because from this year, domestic mobile phones have gradually developed their own 3D structured light.
The Apple iPhone X is the first company in the world to use 3D speckle structure light for face recognition and payment. The iPhone X's Face ID is implemented through the original deep camera system integrated in the iPhone X 'Liu Hai' section. This system mainly integrates infrared lens, flood light sensor and dot matrix projector. When waking up iPhone X, if the infrared camera finds a face, the dot matrix projector will flash 30,000 light spots, then the infrared camera The feedback of these spots will be captured, and a 3D data model of the face will be acquired and compared with the model stored in the A11 Bionic chip. If it matches, it can be unlocked.
The Xiaomi 8 Discovery Edition is the first Android mobile phone to implement a face-based 3D recognition system based on coded structured light technology. Using mask-based coded structured light, through the innovative patented coding technology, the face presents regular geometrically encoded graphics. Quickly match feature points, reduce the amount of 3D information calculation, and reduce the power consumption of structured light algorithms.
Vivo's TOF 3D (Time of Flight) super-induction technology is adapted to a special transmitter to emit modulated near-infrared light. After the infrared light meets a person or an object, it is reflected and then folded back to the receiver. The time difference is used to form stereo vision. Compared with the previous 3D structured light technology, the TOF 3D technology sensor is smaller in size and can collect more information, and the working distance is 3 times that of 3D structured light. It can also be used in multiple scenes. Including 3D face recognition, unlocking, paying, and AR beauty, somatosensory games and AR fittings, some of the iPhone X's 3D structure light is difficult to achieve.
Compared with fingerprints, 3D structured light can further do 'modeling' in addition to biometric recognition. In the future 5G era, for AR/VR, breaking the boundary between virtual and reality has a predictable future.
More 'scare' technology than hardware upgrades Huawei GPU Turbo
Before the official release of GPU Turbo, Yu Chengdong's 'very scary technology' on Weibo caused a heated discussion and conjecture. In the end, GPU Turbo can improve graphics processing efficiency by up to 60% and power consumption by up to 30%. The 'quality change' that is difficult to achieve through hardware upgrades. It greatly improves the instruction transfer efficiency between the CPU and the GPU, reduces the redundant computing consumption of the GPU, and more efficiently completes the CPU instructions.
During the CES AISA in Shanghai, Wang Chenglu, President of Huawei's Consumer Business Software Engineering Department, also used the popular language to popularize the technology principles for the media and consumers: In the game, the adjacent two frames are often the same in many places. The power of GPU Turbo technology is that it can predict the difference between the next frame of the game screen, and only render the scene where the picture changes. For example, 80% of the frames may be consistent between 2 frames, GPU Turbo This will cause the chip to render only 20% of the change, thus reducing the GPU's 80% effort.
For the consumer, the most concerned is the actual user experience. In the case of reduced rendering workload, through the optimization of software and hardware, Huawei GPU Turbo can control the rendering time of the next frame within 7 milliseconds. It is possible to complete the rendering of the next frame in as little as 3 milliseconds, which brings up to 60% of the graphics processing efficiency, which means that Huawei P20 users almost disappear when playing the chicken game, fully enjoy The joy of the game.
And GPU Turbo brings more than just future upgrades, and can cover the past products. This is undoubtedly more significant for all Huawei/Glory users.
to sum up:
This year, the first half of the mobile phone circle officially closed. After taking stock of these new technologies, it is not difficult to find out that today's domestic mobile phone manufacturers can be said to be thick and thin, and no longer only Apple's leader, but strive to develop various black technologies; It’s just that Lu Xun is competing with hardware, but he is concentrating on developing soft power. It is no longer just to follow the trend of conservative sales, but to pursue more standards and tonality. Today’s domestic mobile phone manufacturers also have considerable R&D resources and capabilities. I am able to lead the next new technology in the mobile phone industry, open up differentiated markets, and even go to the receipt of innovation for future extra bonuses.
