On February 23, it was reported that ZTE released its first mass produced off screen camera phone, Axon 20 5G, last year and continued to work in this field. At today's MWC Shanghai Exhibition, ZTE also demonstrated two new technologies related to mobile phones with offline cameras, including offline 3D structured light technology and the second generation of offline camera technology.

Previously, 3D structured light technology has been applied to biosafety identification of some full screen mobile phones, and it is usually necessary to reserve a certain space on the top of the screen to accommodate relevant sensing elements. This time, ZTE made 3D structured light components under the screen, supported 3D face recognition and live detection functions, and reached the security level of payment. At the same time, it can also be used for 3D modeling, AR and other applications.

The second generation of mass production underscreen camera technology it displayed mainly improved the display fineness of the underscreen camera area (the screen is divided into two areas: the main screen and the sub screen, and the sub screen area where the front camera is located is somewhat different from the main screen in terms of fineness and color rendering), and the pixel density of the first generation of 200ppi was increased to 400ppi, Officially, the display effect of the camera area under the screen is more consistent with that of the main display area. In addition, the screen refresh rate has also been upgraded from 90Hz to 120Hz.

However, after upgrading the consistency of screen display, ZTE may also focus on improving the imaging effect of under screen forward photography. In DxOMark's forward photography evaluation of the Axon 20 5G, the phone only scored 26 points, ranking at the bottom of all tested phones.
