2020 may be the year of greatest progress for domestic Android manufacturers.
At the software level, we have seen iterations of excellent operating systems such as MIUI 12, ColorOS 11, and EMUI 11. At the hardware level, more and more domestic "mobile phone manufacturers" have begun to accelerate their own hardware ecosystem and enter the fields of smart hardware such as headphones, watches, and TVs.
▲ MIUI 12
Among them, OPPO is a very representative manufacturer. In terms of system, ColorOS has gradually escaped from the stereotyped and colorful style in the past two years, and has begun to have a design aesthetic. ColorOS 11, which was released this year, has come to the first echelon in terms of visual refinement. What is lacking is the improvement of memory efficiency, 120Hz stability and other underlying optimizations.

Ecologically, OPPO released the "Large Family Bucket" last month, not only the flagship headset OPPO Enco X, but also the smart TV S1 and R1 series, marking OPPO's efforts on the big screen track. Contacting the smartwatch released in March this year, OPPO's ecological layout has taken shape.
The OPPO Future Technology Conference, which has just ended, represents OPPO's achievements in cutting-edge technology.
The theme of this year's OPPO Future Technology Conference is "Leap Transition · Supreme Good". At this two-day Future Technology Conference, OPPO released a total of three concept products and two management systems.
Different flexible screens, scroll screen phones are coming
It is believed that OPPO X 2021 is the most concerned one among the three concept products.
Unlike the folding form of traditional flexible screens, OPPO X 2021 adopts a "retractable" design, and the screen can be extended or retracted like the right side. In the unextended state, the screen size is 6.7 inches, and can reach a maximum of 7.4 inches when extended.
▲ The screen color is distorted after video compression
According to OPPO, when watching a video, whether it is 16:9 or 4:3, you can get a full-screen viewing experience without black edges. When reading e-books or editing documents, it can be adjusted to the size that best suits the user's vision and grip to ensure the best reading experience. In addition, you can also play the game while reading the message pop-up window, the game and pop-up window screens do not interfere with each other, and can be displayed on the screen completely.
Does the animation look a bit like magic? In order to make the screen stretch more softly and smoothly, OPPO designed the "Roll Motor" powertrain: the two built-in drive motors output a constant force through the fuselage. This solution can also effectively prevent the screen from being damaged when suddenly stressed.
It is worth noting that although this screen is flexible, it does not feel "soft" at all. The feeling of pressing down with your fingers is solid, just like an ordinary glass screen.
This is due to the "dual matrix embedded clutch structure." OPPO has designed two left and right pallets inside the fuselage. When the screen is unfolded, one of the pallets can slide out synchronously. The left and right pallets support the unfolded screen and keep the screen smooth; when closed, the two The pallets can be seamlessly spliced into the same plane to keep the screen flat and hard.
In addition to the "black technology" in form, the design language of OPPO X 2021 is also very eye-catching. The lines on the back are not vertical, but have a certain slope. With the screen and metal material, it looks dynamic and textured.
It can be said that the arrival of OPPO X 2021 has further opened up the space for the flexible screen market and further expanded people's imagination.
AR glasses, not necessarily bloated
At this Future Technology Conference, "AR" has become a frequently occurring word.
The first is the new generation of AR glasses-"OPPO AR Glass 2021". At last year's Future Technology Conference, OPPO showed the first generation of AR glasses. Although they are very sci-fi, they are not friendly enough in size, a bit like a small helmet.
▲ OPPO's first generation AR glasses
In appearance, the new generation of AR concept glasses adopts a new split design, the weight is reduced by nearly 75% compared with the previous generation, and the volume is also a lot smaller.
In terms of core components, OPPO AR Glass 2021 uses a new "Birdbath" optical solution. Compared with the previous generation AR glasses, the image contrast can be improved by 53%, and the brightness uniformity can be improved by 98%. Let the virtual picture and the real environment better integrate.
OPPO AR Glass 2021 has custom-made 94-square-millimeter large-amplitude speakers on the temples. With the double 0.71-inch OLED screen refraction effect, users are like watching a 90-inch large-screen TV 3 meters away.
In terms of gesture interaction, OPPO AR Glass 2021 integrates a binocular fisheye lens, a ToF depth sensor, and an RGB sensor. It can realize the detection and tracking of both hands in milliseconds. For example, the glasses can easily recognize the precise operation of the user, such as tapping the menu, pushing away or zooming in.
ToF and binocular fisheye lens can also cooperate with IMU to complete spatial positioning tasks. OPPO AR Glass 2021 can achieve centimeter-level positioning accuracy within 1°, and constantly update and feedback the user's real-time position in space. Laid the foundation for AR applications such as indoor navigation.
Currently, OPPO AR Glass 2021 has been equipped with self-developed applications such as multiplayer MOBA games, tower defense games, and AR cameras. We experienced a two-player battle game on the spot, and we believe that more interesting scenarios will appear in the future.
CybeReal, enough cyberpunk
In addition to AR glasses, OPPO also released a full-time spatial computing AR application-"CybeReal".
According to OPPO, CybeReal includes three core supporting technologies: digital reconstruction of the physical world, full-time high-precision positioning, and OPPO cloud services. How to understand? Simply put, this application uses the camera to recognize the space, and can provide you with diversified information services according to your location and space.
This is based on manual collection and third-party data. CybeReal first digitally reconstructs the physical world and draws it into a digital model with centimeter-level accuracy. It uses multiple sensors and algorithms to determine spatial positioning, thereby providing users with timely information service. These capabilities are all completed on OPPO's cloud.
It sounds very esoteric, but in fact, it is easier to understand its logic after the hand. To use an inappropriate metaphor, it is a bit like a three-dimensional navigation, which can provide centimeter-level route guidance indoors and outdoors, while displaying the information you may need in the form of AR.
However, CybeReal currently only supports some locations in Shenzhen. OPPO still has a long way to go if it wants to widely apply nationwide. On the other hand, CybeReal can only be experienced on engineering machines for the time being, but the usage logic of CybeReal is more compatible with AR glasses. OPPO Vice President and Dean of the Research Institute Liu Chang also revealed that CybeReal will be applied to AR glasses in the future.
A stronger system for "portrait photography" is here
As far as "selfie" is concerned, the blue and green factories deserve to have names. This time OPPO took another step forward in portrait photography, releasing the "OPPO FDF Full-Dimensional Portrait Video Technology System".
The core of this system contains two engines, one is the perception portrait engine, and the other is the image quality enhancement engine.
Let me talk about the "perceptual portrait engine" first. According to OPPO's image product manager, this engine has functions such as AI face detection, AI ultra-clear portrait, OFL skin quality optimization algorithm, and face distortion correction. In other words, it is more accurate face recognition, clearer portrait shooting, softer skin tone, and more accurate distortion correction.
What is more interesting is the "OFL skin quality optimization algorithm", which can perform AI processing on skin color and skin quality separately. The skin color will not be "false white" while making the skin more textured. In addition, the detection range of this algorithm includes not only facial skin, but also neck and hand skin.
This technology allows users to take portrait photos and videos without worrying about the embarrassment of "the face and neck are not the same color". It is still very friendly to Vlogger.
In addition, this algorithm will intelligently retain "innate features" such as beauty moles. Like "acquired blemishes", such as acne and scars, it will be automatically wiped off, making the beauty effect more natural.
Next, let’s talk about "Image Quality Enhancement Engine". This engine mainly includes a new generation of super anti-shake algorithm, mobile time-lapse photography, super night scene video, DOL-HDR and other functions. Simply put, users can take more satisfactory pictures in scenes such as large screen jitter, insufficient light/over bright, etc.
These functions can be roughly understood by just looking at the names. We are no strangers to things like super night scenes and mobile time-lapse photography. Among them, "DOL-HDR" may need to be explained. This scheme is mainly to achieve "backlight shooting clearer." The long and short exposure frames are carried out almost at the same time, which greatly reduces the time between the previous and subsequent frames. The advantage is that it can achieve better HDR video shooting effects and improve the ghosting problem.
"It’s not as good as everyone’s music." OPPO announced that it has gradually opened up technologies such as HDR, night scene, and super anti-shake to third-party platforms. In addition, the first new product equipped with OPPO's portrait video technology system will come out in December.
Full link color management system launched
For me, the quality of the mobile phone screen is more important than the camera ability. Because when we use mobile phones, we do not interact through the window of the screen all the time, so its quality greatly affects the user experience. OPPO released the "Full Link Color Management System" at the conference to improve the display problems of the mobile terminal.
OPPO full-link color management system has two core technologies, one is full-link 10bit, and the other is color management.
The first feature of the full link 10bit is "full", which covers the entire image processing process of acquisition, encoding, storage, decoding, and display. It has the ability to process 10bit data in each link, and solves the incompatibility of the underlying system with 10bit image information. problem. Another feature is "new", OPPO said that this is the first time in the mobile phone industry to achieve a full-link 10-bit picture and video shooting system.
A small detail worth noting is that this color management system will encapsulate and store images in HEIF format. Friends who use iPhone are already quite familiar with this format. Its advantage is that it supports up to 16bit image data storage and the compression algorithm is more efficient. Compared with the JPEG format, the same image information can save 50% of the storage space.
Color management is another core technology, and its main task is to solve the problem of color deviation. In theory, after adopting this technology, the color difference caused by the different color gamut description methods will be "eliminated" from the collection end to the display end.
OPPO also said that in 2021, the Find X3 series will be launched with a full-link color management system. In addition, it was announced that it would introduce the "Color Compensation System 2.0", designed for screen display in two modes, normal and professional, which will be more friendly to people with color vision impairment.
"3+N+X" Technology Transition Strategy
At this year's Future Technology Conference, OPPO, with its wings and wings, for the first time put forward the development concept of "Technology for people and good for the world". The explanation given by OPPO founder and CEO Chen Mingyong is: In the process of technological innovation, we must pay attention to avoiding being behind the opponent due to fear and not caring about people's needs, which will become "blind innovation."
In addition, OPPO also announced the "3+N+X" technology transition strategy for the first time.
"3" refers to the basic technology of hardware, software and services. Among them, hardware is the carrier, such as mobile phones, headsets, televisions, etc.; software refers to basic software, system architecture, etc.; services include four service capabilities: big data, machine learning, cloud computing, and smart services.
"N" refers to the long-term competence center built by OPPO, including artificial intelligence, security and privacy, multimedia, interconnection, etc. These can be understood as OPPO's housekeeping skills.
And "X" refers to OPPO's differentiated technologies, including images, flash charging, new forms, AR, etc. For example, the "scroll screen" concept phone released at the conference is a manifestation of its differentiated technology.
OPPO also announced at the conference that within three years from 2020, it will continue to invest 50 billion yuan in research and development expenses, and "3+N+X" will be the focus of the next stage of research and development.
The scroll screen, AR glasses and applications, and two management systems can be said to be exciting enough for OPPO's Future Technology Conference this year. The "restlessness" of the "green factory" is believed to also stir up domestic Android manufacturers to accelerate the pace of innovation. In the next three years, there will be good shows.
