Several companies have been playing with the idea for some time, although the first to launch a terminal with the camera under the screen was ZTE, in the ZTE Axon 20 5G. Almost six months later, the company already has the second generation of its under-screen camera technology.
It is not the only novelty that ZTE has announced at the MWC in Shanghai. The company has also presented the first structured light technology under the screen, capable of 3D facial recognition.
Camera under screen 2.0
The ZTE Axon 20 5G is the first mobile put on sale that incorporated the front camera under the screen. It is a successful technology, although not perfect: you continue to see the profile of the camera from an angle or if you pay special attention to this area. Basically you could tell that « there was something strange » in the square above the screen, either lower resolution in the image or a small black frame.
These problems have been polished in this second generation. To begin with, the resolution of the « patch » that covers the camera passes 200 dpi to 400 dpi. This, according to ZTE, is a more consistent result with the rest of the screen.

3D facial recognition, also under the screen
It was not the only technology that found its place under the screen during the ZTE exhibition at the MWC in Shanghai. The company has also announced the first 3D structured light technology under the display. That is, something like a ToF under the screen.
Instead of being a 2D image, as in the case of the camera under the screen, this technology allows the phone to capture structured 3D light like that of a ToF or a LIDAR. Its possible applications range from 3D facial recognition to 3D payments, 3D modeling, augmented reality, and the like.
