Xiaomi's VP explains why under-screen cameras aren't coming anytime soon

Ro, 29 January 2020

With the push for full-screen design on modern smartphones, many solutions have appeared to get rid of or hide the front-facing cameras. The mechanical pop-up cameras, punch-holes and all sorts of cutouts and notches are the stepping stones and many believe having the camera under the display would be the final and most elegant solution. Unfortunately, though, according to Xiaomi's VP, that's not happening anytime soon as there are still major technological challenges to be overcome.

Xiaomi's VP explains why the current tech can't figure out under-screen cameras

Lu Weibing says the whole smartphone industry is working hard on the solution but despite Xiaomi showcasing its prototype in 2019 with under-screen camera, there are two main factors that need to be considered. First, the pixel density of modern displays is too high to accommodate a camera underneath as it blocks too much light. The PPI appears to play a significant role in the camera's light transmittance, which brings us to the second hurdle.

The light transmittance of current in-screen cameras is too low and combined with the high PPI, very little light reaches the sensor. That means the image quality isn't anywhere near the one offered by regular cameras. Researchers are still looking for a way to achieve high PPI without interfering with the camera's light transmittance.

Let's face it - no one will buy a smartphone with a display that has low pixel density nor would many settle for a sub-par selfie camera experience.

All in all, Lu Weibing says that we shouldn't hold our breath for the tech and we may have to wait a bit longer before it becomes available to the end consumer. While he gave no timeframes, it's looking at least a couple of years out.

Agree! There should be a no-selfie camera phone option atleast. I barely use it yet I will be getting an S10+ with huge ugly pill for that.

I mean NO self camera at all, no hidden / flipping / otherwise hiding self cameras

True, after pop up camera who have the advantage for privacy, a decently sized bezel is my second favorite option (if I have to have a camera facing me I prefer one I can hide without dealing with the tactile, having the advantage of lots of addition...
