About technology camera under the screen, the so-called CPU (Camera Under Panel) we've heard it many times. Xiaomi has been developing this technology for a long time and now we are coming up with new information that is not exactly pleasing.
Production is extremely demanding
General manager of the brand Redmi, Lu Weibing, He said they could not currently find an effective enough solution to combine the camera's functions with those of the display. Simply put, the discrepancy between PPI (display fineness) a screen throughput This is why the production of cameras under the display is in sight.
The current PPI value on the screen is about 400, at this level of pixel density the light transmission in the camera is very low. This significantly affects the quality of the photo.
If the PPI decreases and the throughput increases, there will be a big difference between the camera PPI and the full screen PPI. This will result in, for example, color spots in the camera area.
"Therefore, with the current technical capabilities, it is not possible to find an effective solution that takes into account both display and camera effects," explains Lu Weibing, adding that the technology is "still far from achieving mass production."
This statement does not necessarily mean that we will not see a commercially available phone with a camera under the screen, but it does suggest that development may take some time. It is also possible that Xiaomi will be overtaken by another manufacturer in this technology.
