ZTE Under-Display 3D Face Scanner
ZTE demonstrated its under-display 3D face scanner at Mobile World Congress Shanghai 2021 today, and this technology means that users will be able to unlock their devices without requiring a notch or hole-punch cutout area. Eventually, this technology can be used for augmented reality, mobile payment authentication, 3D modeling, and more. There’s no word yet on what devices may use this face scanner, but the company is releasing their Axon 30 Pro handset soon. Read more for a video and additional information.



The company also showcased their second-generation under-display selfie camera and showed that it handles brilliantly in low-light situations. Plus, they have managed to reduce the haze effect seen in the area above the camera, which plagued the first-generation technology, with increased pixel density.
