ZTE has created a Face ID sensor that hides under the screen

During the MWC in Shanghai, ZTE showcased its second-generation sub-screen camera technology. It introduced the function of biometric face scanning based on three-dimensional structured lighting technology, which is used for the first time for such a subscreen solution.

The technology of three-dimensional structured lighting itself as a biometric security system has long been used in smartphone models. Suffice it to recall at least several of the latest generations of Apple’s iPhones and their Face ID sensors. However, due to its size, such a biometrics module requires a cutout in the device’s screen, also popularly called “bangs.” ZTE’s new second-generation sub-screen camera lets you say goodbye to the notch that takes away precious display area.


ZTE’s biometric camera security system is based on the 3D face recognition function, which offers more reliable smartphone protection from unauthorized access. As a demonstration, ZTE posted a video with three smartphones.

The first two devices in the video are equipped with two-dimensional face recognition, and therefore falsely triggered to unlock the device using a photograph of a person.

Only the third smartphone, equipped with spatial or three-dimensional face recognition, did not react to the photo.

The function’s principle is that first, the camera sensor uses infrared light to collect two-dimensional information about the user’s face.

Then, using a laser dot matrix, information is collected from a spatial image of a person’s face.

After that, special camera algorithms combine the received data to create three-dimensional maps of the user’s face, and after verification, they allow you to unlock the phone. Essentially, that’s what Face ID does in Apple smartphones. But ZTE has all the necessary sensors and other elements hidden under the screen.
