If MWC is described as a golden mountain full of black technology, oppo is one of the most eye-catching manufacturers on the stage of mwcs2019. At present, the best comprehensive solution - off screen camera technology was unveiled at the meeting. And the engineering prototype displayed has been quite mature at the hardware structure level, which is infinitely close to the standard of mass production.The same as Shen Yiren's previous exposure, the engineering machine equipped with oppo under screen camera technology looks no different from the ordinary screen from the surface, but there is a camera hidden under the screen. After lighting up the screen and switching several, the sense of existence of the camera is completely invisible. Only when the self timer is started, the small screen above the camera will be turned on, and the front camera function can be perceived when it is close to the camera.What about? Can't you see where the front camera is from the GIF diagram? How is oppo designed to skillfully hide the camera under the screen without affecting the shooting? Therefore, I wrote this technical article to deeply analyze the mystery of oppo under screen camera technology.
01 the realization of off screen camera technology is the key conditionTherefore, I found the patent map of under screen photography applied by oppo on June 4, 2018.From the above figure, we can see the scheme behind this technology: the screen is divided into light transmitting area and non light transmitting area. The light transmitting area is more like a transparent mirror, and the real screen is part of the non light transmitting area.
Below the light transmission area, there are two components, one is the imaging and projection component for photographing, and the other is the processing unit connecting the light transmission area and the non light transmission area. To realize this design scheme, we need not only a team with profound technical heritage to create, but also perfect scientific and technological support to turn "imagination" into reality. It can be seen that oppo realizes this technology.Oppo's off screen camera technology demonstrationIt is worth mentioning that the processing unit plays the role of "central control hub" in these components, which is used to connect the light transmission area and non light transmission area, and also controls the processing task of self photographing images. This small processing unit is the core of the oppo off-screen camera.
In the patent diagram in the lower part of the figure above, we can also clearly see that there are elements below the projection element and the imaging original. In fact, based on the effects of the two components, a "self start" effect is added. When the imaging component works, the photosensitive element and the photographing element below are closed, and when you turn on the self photographing, Conduct "behavior perception" through the driving element to wake up the imaging and photographing function of the photosensitive element.02 when is mass production? Let's first look at the path before oppoIn fact, it took less than two months from the official release of 10x hybrid optical zoom technology by oppo in mwc2019 to its official listing. It can be seen that oppo is accelerating the speed from technology realization to product landing.
For oppo, it is neither difficult nor easy to convert "ideas" into "concepts" and then "concepts" into "reality". The process is not like some toothpaste manufacturers, but practical, step by step, better combining product experience and practicability, and finally presenting it to users.We are used to seeing comprehensive screens in the form of "bangs screen", "water drop screen" and so on. The previous double track periscope structure and lateral rotation lifting structure of find X are really comprehensive exploration results. The off screen camera scheme is the best way to achieve 100% of the total screen. Although oppo did not disclose the timetable for the real commercialization of the off-screen camera technology, it is believed that the final product will meet us soon. At least in the whole industry, oppo will be the first one.03 the process from scratch is based on oppo's inheritance gene at the level of technical iteration
In MWC 2016, oppo launched vooc flash charging technology. At that time, the improvement of mobile phone battery capacity had reached a bottleneck. From a perspective, it is an important way to improve the battery life of mobile phones by allowing users to maintain a long-lasting power through rapid charging.Mwc601oppo launches super vooc flash charging technologyWhen the mobile phone imaging technology develops to a certain extent, the competition between pixels has become meaningless. The needs of users are no longer limited to shooting more clearly. If we still blindly compete in pixel data, there will obviously be no greater breakthrough.
Oppo's 5x optical zoom technology launched in MWC 2017 brings the industry's thinking on the impact of mobile phones to another dimension. To see further and more widely is the real potential demand of users.Mwc2017oppo launches 5x optical zoom technologyTime has proved that oppo's idea of influencing development is correct. By the beginning of 2019, oppo has upgraded the zoom technology to a new level again. The release of 10x hybrid optical zoom technology has brought a wave of impact not only to the existing mobile phone, but also to the professional camera market.
Mwc2019 oppo releases 10x hybrid optical zoom technologyOppo Reno, which has a 10x hybrid optical zoom capability, was officially released in April. At this time, other brands of mobile phones with multi focus and multi lens solutions also began to be released one after another. Up to now, oppo Reno, with up to 60x digital zoom capability, still remains the industry leader in terms of extreme zoom capability.04 only down-to-earth innovation can go further
Oppo is the only pure mobile phone terminal brand to enter the top 5 in the list of patent authorizations in China in 2019. At present, the mobile phone industry has upgraded from the early supply chain competition to the competition of core technology. Each manufacturer is building its own "technology", and in this long-lasting battle, oppo actually has a layout for a long time.Oppo has always invested heavily in technological innovation and R & D. at present, in addition to the research institutes of Shenzhen headquarters, including Beijing, Shanghai, Dongguan, Japan and the United States, oppo has set up special R & D centers in the fields of industrial design, new materials, AI algorithms and 5g.Any company leading industry innovation is based on the accumulation of long-term core technology complete R & D system support. The display of off-screen camera technology is only a result we see, and what really represents in the deep level may be the integration of hundreds of technologies and thousands of experimental tests.
Oppo is constantly delivering value to users in its own way. The off-screen camera technology may be just the tip of the iceberg. There will be more ways to change the future in the future, which is worthy of our expectation.
