ZTE announces its second-generation under-screen camera and first 3D under-screen recognition.
Several companies have been toying with the idea for some time, although the first to launch a handset with an under-screen camera was ZTE, in the ZTE Axon 20 5G. Almost six months later, the company has the second generation of its under-screen camera technology ready.
This is not the only new feature ZTE has announced at MWC Shanghai. The company has also presented the first structured light technology under the screen, capable of 3D facial recognition.
ZTE announced its Under-screen camera 2.0
The ZTE Axon 20 5G is the first cell phone put on sale that incorporated the front camera under the screen. It’s a nice technology, although not perfect: you can still see the camera profile from an angle or if you pay special attention to this area. It was noticeable that “something was off” about 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. For starters, the resolution of the “patch” that covers the camera has been increased from 200 dpi to 400 dpi. This, according to ZTE, means a more consistent result with the rest of the screen.
3D facial recognition, also under the screen
It was not the only technology to find its place under the display during ZTE’s exhibition at MWC Shanghai. The company 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 under-screen camera, this technology allows the phone to capture 3D structured light like that of a ToF or a LIDAR. Its potential applications range from 3D facial recognition to 3D payments, 3D modeling,
