Xiaomi's Mi Mix 4 could also feature an in-display selfie camera

What you need to know

  • Xiaomi teaser shows off a phone with an in-display camera module.
  • We could see the module make its way onto the Mi Mix 4.
  • OPPO showcased its own in-display solution earlier today.

Update: Wang Xiang Senior VP of Xiaomi posted to his Twitter to give some insight on how the new under glass selfie camera works.

After wowing us with a tweet showing off a working selfie camera under the display, Xiaomi Senior VP Wang Xiang tweeted out an explanation on how the setup works. In a series of four infographics, he detailed how the new screen utilizes a small transparent area on the screen with low reflective glass. This allows for light to travel through the glass both ways, providing you a display when you need it, and permitting light to shine through to the camera sensor when it is time to take selfies.

Hot on the heels of OPPO, Xiaomi is highlighting its own in-display camera technology. The teaser video shows off a Mi 9 prototype with a notchless design next to the standard Mi 9, and in spite of the lack of a front camera, the camera shows a live view of the room.

Xiaomi was granted a patent for an in-display camera solution, with a smaller secondary display tucked away behind the main panel. With the Mi Mix series designed to provide an all-screen front with no bezels or cutouts, it's likely Xiaomi will want to showcase the technology in the Mi Mix 4.
