Under Display Selfie Camera Phone: Next Level Technology

I’m guessing that you all have heard about  “under display selfie camera” Technology.
Well, let’s get some information about this new technology.

Last year oppo announced that they are going to launch this Technology but we didn’t here anything more on that till now.
By the way this Technology is pretty cool,
the screen of smartphone contain a little area on the upper middle side that light up when the screen is on and the pixel in that area turn off when you open your camera which allows light to go through the screen.

If you want to see your camera you can do it by moving the phone at certain angle.
So, oppo is going to use this Technology in their upcoming smartphones camera. But they still haven’t yet. But I think they are going to launch this tech very soon because we know that if you don’t make something first someone else will.

At this point I think that someone is ZTE, that launched ZTE AXON 20 5G in this September. This is a middle range smartphone with fairly good Technology. If we talk about its specifications, we got

This is the first smartphone with under display camera. And this smartphone is really cool. But I know that you are wondering how this thing work so let’s get it over with.

How does it works?

Its working is quite simple, the small area that hides the camera is less in resolution than the remaining display. Resolution is smaller means there is a pixel gap which allows light to pass.

It is an Oled, that means if you want to turn off individual pixels you can do it. These turned off pixels are same as semi translucent which allows light to enter through it. At the end they use a polarizer that cut the effect of reflection and refraction of light so that the image that enter inside the camera is clean and crystal clear.

I’m really excited that the Technology is finally going available in upcoming smartphones. What do you think about this tech?
