Xiaomi Mi MIX 4 with in-display camera? The Chinese manufacturer has filed a new patent that is considered to be the next Mi MIX 4 smartphone. The patent, entitled “Display Structure and Electronic Equipment”, describes a camera hidden under the screen that does not “eat” space on the display. In the patent, it is shown that the display structure includes a screen and a light adjustment part located on one side. From what you can imagine, when the front camera is active, the pixels relating to the portion of the screen concerned are turned off to avoid disturbing the incoming light. This would clearly involve the use of a OLED (or microLED, but we are still far away for them). That the presentation of the Xiaomi Mi MIX 4 takes place at CES 2020 in Las Vegas or at the MWC 2020 in Barcelona? We’ll see.
