As part of its exhibition at MWC (Mobile World Congress) 2021, held this year in Shanghai, ZTE demonstrated the second generation of its under-screen camera phones, mentioned above. And it demonstrated this in the best possible way: by bringing prototypes so that visitors could see the new features with their own eyes. In addition, ZTE brought another prototype to show its new facial recognition technology in 3D.
The company's first attempt at manufacturing smartphones with an under-screen camera was the ZTE Axon 20 5G, launched in November 2020. However, the device was not well received, and the main reason given for this was, ironically, the quality of its cameras. In addition, the cell phone was not properly optimized, which made it necessary to use it horizontally to access all the available icons, for example.
What's new in the second generation
Both ZTE official profile as much as Lu Qianhao's profile, responsible for the company's marketing division, posted information about the prototype on Weibo. Consequently, they also apply to the second generation of phones with this different type of front camera. First of all, there was a jump in pixel density on the screen where the camera is located: the 200 ppi of the previous generation was doubled, resulting in 400 ppi.

In practice, this means more definition and detail in the images and videos seen through the screen. Another feature that received a nice upgrade was the screen refresh rate, increasing from 90Hz on the ZTE Axon 20 5G to 120Hz.

Furthermore, the visual difference between the entire screen and the specific part where the camera is located has decreased, meaning the screen’s fluidity has become more natural. Perhaps this difference in the second generation is ZTE’s response to criticism that the camera under the screen was not as invisible as it should have been in the first generation. Although the information in the posts ends there, Lu Qianhao assures at the end of his post that “There are more qualitative leaps to come, which will bring new and incredible experiences, so stay tuned!”
A 3D scanner under the screen
ZTE also took advantage of the event to announce its new 3D scanning technology, which involves what is generally called a structured light scanner. Basically, the technology captures the shape and various characteristics of a given object through light rays, which are reflected by the object and result in its three-dimensional “impression”.

Although this technology is not new, it is the first time it has been demonstrated on cell phones. In fact, what is even more new is its demonstration on a device with a camera under the screen. On smartphones, the use of this technology will allow for much more accurate and secure facial recognition than the current standard, which works based on 2D images. In addition, the technology can also be used for 3D modeling and virtual reality, just to name a few examples.
ZTE's display wasn't limited to its second-generation under-screen camera or its new 3D scanner, but contained numerous products of smart home on 5G, as well as headphones and other smartphones 5G. However, their participation at this year's MWC will certainly be remembered for their under-display camera devices. And we certainly look forward to learning more about them.
