Xiaomi has been working on under display cameras (or as some call them, under panel cameras, UPC) for years, but is yet to actually launch a phone with one. The Mi 10 Ultra was supposed to be the first, but that didn’t pan out. It didn’t happen for the Mi 11 Ultra either. But now the Xiaomi Mi Mix 4 is getting ready for launch and this one may be it – Xiaomi has finally figured out how to truly hide the under display camera, says Ice Universe.
The camera will be completely invisible to the naked eye when not in operation. However, an earlier rumor claimed that the display will be limited to 1080p+ resolution. This panel will reportedly be supplied by Huaxing Optoelectronics.
While Xiaomi has patented a design with a quad-curve display, the Mi Mix 4 will use a more standard dual-curve display to save on costs. It is already rumored to be pricier than the Mi 11 Ultra – that means it will be more than CNY 6,000 ($930/€790), which is the Ultra’s starting price (it was much, much higher than that in Europe, €1,200).
HoiINDI has created renders of the back of the device, showing a secondary display next to the camera, though larger than the one seen on the Mi 11 Ultra.
There’s also a video that shows the phone from all angles:
It will not be completely invisible..
What are you talking about ? The rear display would not mirror everything displayed on the main display. It's main function is for using the main camera for selfie, smaller always on display, and show whatever you want to show on it.
I doesn't like this phone it's rear display. That is why it doesn't protect what am I saw in the phone. It will be seen everyone what am I see in this phone. Use this phone a thief can see our mobile banking password & any other so...
