Oppo has just announced its latest under-screen camera technology. So according to them, this technology allows a selfie camera to be placed under the display. This technology could be taken care of on several phones before, but the pixel density of these phones began to decrease. So this was due to an exposure problem in this camera. Oppo has used smaller pixels to keep the 400-PPI sharpness as a solution to this problem. So according to Oppo, as a result of using these smaller pixels, users will not be able to see any visual difference in the photos. Oppo has also posted several sample images on the internet to check the quality of this camera. So when you look at these 30 photos you can see some color artifacts, but you can see a big improvement in this camera which works with the previous under-display cameras. Although Oppo makes this new under-display camera, no information has come from the company about the commercial device that has this camera. So we think we will not have to look at a device with this camera soon.
