At CES 2020, OnePlus brought the concept phone Oneplus Concept One. If you are disgusted with the “Yuba” and “Mahjong” multi-cameras that may appear in large numbers this year, OnePlus will now solve this problem by latent hidden rear-camera.

OnePlus is not a PPT-driven company, and the concept machine does not have to have exaggerated technology. What OnePlus hopes to convey is the “concept” itself-to the utmost detail, so that the product is not bloated and users are not burdened

When you don’t use the rear camera, you will be “stealthy”. Does the pioneering “latent hidden rear camera” brought by this OnePlus concept machine look good with new electrochromic technology.

Just before the official launch of CES20, OnePlus released the first concept machine OnePlus Concept One in Las Vegas. Different from the black body in the previous official trailer, the concept machine on the scene was designed by McLaren. The iconic combination of yellow leather and black glass is highly recognizable, and the two stitches on the back cover refer to Classic elements of Karen sports car seats. In addition, the rear camera module of the mobile phone is not raised, which should be praised.

At the same time, OnePlus applied the physical vapor deposition (PVD) process to the aluminum alloy middle frame for the first time in the industry. After 24K real gold was vaporized, it was attached to the middle frame to form a coating film, creating a jewelry-like texture.

OnePlus Concept One Technology Behind Hidden Camera

Of course, the biggest highlight of the OnePlus Concept One is the “hidden rear camera” on the back of the phone. OnePlus stated that the primary purpose of this design is to solve the challenge of multi-camera arrangement on the mobile phone industry design: the glass cover above the rear camera uses the “electrochromic” technology commonly used in aircraft and cars, by applying different Current and voltage change its transparency. Usually the camera is hidden under the black glass. When the camera is started, the glass becomes transparent and the camera is exposed.

To apply “electrochromic” technology to mobile phones, it is necessary to overcome the size limitation and the impact on power consumption, and at the same time ensure the amount of light entering the camera and a sufficiently fast color-changing response speed.

For this reason, during the research and development process, OnePlus adjusted the electrochromic EC material formula, improved the upper and lower glass structures, optimized the driving and optical design, etc., to achieve a thickness of 0.35mm for the entire electrochromic glass component, which was similar to ordinary tempered film It’s no different, at the same time the glass changes from black to transparent in 0.7 seconds, which is equivalent to the time to launch the camera app.

The official said that this is currently the industry’s thinnest, highest light transmittance, and the fastest discoloration of electrochromic glass. As for power consumption, OnePlus introduces that the latest version of the concept machine is used to simulate the frequency of normal camera use by ordinary users, and the power consumption per hour only increases by 1-2 milliamps.

In addition, taking advantage of the characteristics of electrochromic glass, OnePlus has also added the ND filter (dimmer filter) function in the professional mode of the system’s built-in camera app, which controls the amount of light entering the lens through physical means, which can be used in strong light or slow door for better imaging.

The official said that the current function can reach ND8 level, which is to reduce the amount of incoming light to a normal level of 12.5%. However, from the effect of the hands-on experience on the spot, currently turning on the ND filter mode will affect the color temperature of the imaging. OnePlus’ engineers responded that they have noticed this problem and are optimizing it.

OnePlus Concept One Availability

In the end, OnePlus did not announce the exact launch time of the production machine equipped with a “hidden rear camera”, saying that the current major issue to be solved is the yield rate of electrochromic glass, and related products will be launched at an appropriate time. Do you expect such a phone to go on the market?
