Mobile phone "hidden hidden camera" concept debut, this A-share company supplies core materials

Time: January 8, 2020 13:45:15 China Finance
Too many cameras that may affect the aesthetics of mobile phones may have to be resolved. No, the "hidden rear camera" mobile phone is officially unveiled!

The 2020CES (International Consumer Electronics Show), which is leading the future trend of consumer electronics, is in full swing in Las Vegas, United States. The latest news shows that OnePlus officially released the world ’s first Camera "concept machine OnePlus Concept One.

The so-called "hidden rear camera" mobile phone, that is, the entire rear camera module of the mobile phone is hidden under the rear glass of the mobile phone. When the rear camera is not used, the black glass lens is integrated with the surrounding glass, and the user is almost aware Without the presence of the lens, just like the mobile phone does not have a rear camera, only when the camera is needed, the glass on the rear camera lens will become transparent and make it appear.

However, a Securities Times e company reporter learned from the company that the phone is still a concept phone, that is, there is a product, but it has not yet been mass-produced. It is the same as when Samsung and Huawei released folding-screen phones in CES in 2019. It will take time. "The company hopes to mass-produce as soon as possible," OnePlus said.

It is worth mentioning that, as a mobile phone with the latest technology in the world, the "hidden hidden camera" mobile phone is leading the mobile phone industry's consumption trend. What technology or material is used to achieve this effect? What is the core material supplied by which company?

"No back camera" mobile phone coming?

It is understood that the realization of latent hidden rear camera relies on the application of electrochromic glass. The rear camera lens glass uses organic small molecule electrochromic material, which can realize the rear camera glass from black to transparent and invertible under the action of an electric field. The color phenomenon is essentially an EC film undergoing a redox reaction to change its transmittance or reflectance to light. It appears as a reversible change in color and transparency in appearance.

In fact, electrochromic technology is not a new technology. As early as the 1930s, there were preliminary reports on the technology. In 1999 and 2004, the glass curtain walls of Stadt Sparkasse Savings Bank and Swiss Re Insurance Building were used. Electrochromic glass.

The electrochromic glass was really well known to the public in July 2008. At that time, the cabin glass of the Boeing 787 airliner adopted electrochromic technology, which brought passengers a fantastic color-changing effect and intelligent experience.

At present, electrochromic glass is mostly used in super running, aircraft and other fields. OnePlus is the first company to try to apply electrochromic technology to the mobile phone industry. It is reported that after continuous debugging, the OnePlus R & D team finally reduced this glass and applied it to mobile phone cameras with very high lens requirements, and controlled the thickness of the electrochromic glass to 0.35 mm. Not only that, after a lot of adjustments and tests, the OnePlus team achieved the ultimate electrochromic speed-0.7 seconds.

Undoubtedly, the reduction and application of electrochromic technology to mobile phone cameras with extremely high lens requirements means that there are a lot of problems to be overcome, such as solving the problems of light transmittance, response speed, miniaturization, and ultra-thinness.

It is understood that, in addition to improving the visual aesthetics, the "latently hidden" mobile phone with electrochromic technology also has practical application significance for camera imaging: by adjusting the transparency and color depth of the glass, the rear lens glass Become a polarizing lens, allowing users to take clear and detailed photos under strong light.

Woog Optoelectronics supplies electrochromic glass?

The concern is, which company supplied electrochromic glass to OnePlus?

On the morning of January 8th, it was revealed that the one-piece electrochromic solution and ultra-thin device used by the OnePlus "latent hidden camera" concept machine are from A-share company Voge Optoelectronics . After two years of research and development, Vogel Optoelectronics has developed transparent nano-level circuits on glass through a special process, which enables the glass to display different colors when powered and unpowered, and has developed the world's first mobile electrochromic process.

It is worth mentioning that Voge Optoelectronics has now solved the mass production problems that the public is most concerned about. It is understood that Vogel Optochromic Glass has achieved mass production with an annual production capacity of 100 million pieces, which can meet the needs of the high-end mobile phone market.

However, on the morning of January 8th, when Securities Times · e called the Secretary of the Board of Directors of Voge Optoelectronics , the company said, "Where did you see this information? I do n’t know much, and I need to check it again." The Canadian mobile phone did not give a clear reply to the reporter's question about the supplier of electrochromic glass.

Public information shows that Voge Optoelectronics was established in December 2009 and is headquartered in Xinyu City, Jiangxi Province. It is one of the leading companies in the domestic flat panel display (FPD) optoelectronic glass finishing industry, and its main business is the FPD optoelectronic glass finishing business. FPD photoelectric glass (mainly a thin film transistor liquid crystal display, that is, TFT-LCD) is mainly used in mobile smart terminal products such as smartphones and tablet computers after the company's finishing. The company's main customers include Shentianma, BOE, TCL Group , CPT, Leibo Hi-Tech , Innolux.

Industry insiders pointed out that "latent hidden rear camera" mobile phones have solved the pain points that many mobile phone users think that too many cameras affect aesthetics. At the same time, as five or even ten cameras appear in the future, latent hidden rear camera may be the optimal solution. It is expected to become a new trend in the future mobile phone industry.
