For the last couple of years, Android OEMs have been developing under-display camera technology and we have seen many prototypes from Samsung, Oppo, and Xiaomi for the same. The technology is finally getting mature to make its way to actual consumers and Chinese OEM ZTE has already mentioned that upcoming ZTE Axon 20 5G will feature an under-screen camera. Just a few days later, Xiaomi has also published a video showcasing its third-generation under-display camera tech and the company will go into mass production in 2021.
Xiaomi first released its under-display camera tech in June 2019, along with a similar solution from Oppo. Earlier in 2020, Xiaomi explained that its under-display camera is still far away from the mass production. The company has now overcome many difficulties over the last couple of months as its latest version looks very promising.
In a video released by the company itself, we can say that this technology will finally let phones have bezel-less look without using any moving mechanical parts.
In a blog post for the same technology, Xiaomi explains that this third-gen technology for the under-display camera the company has, “greatly improved the full-screen effect through self-developed pixel arrangement, and through the optimization of the camera algorithm, allowing it to show the same performance as conventional cameras.”
The new pixel arrangement utilized in Xiaomi’s latest solution lets the forward pass light through the gap between sub-pixels, allowing every single pixel to retain an entire RGB sub-pixel layout without sacrificing pixel density.
When compared with other manufacturers’ solutions, Xiaomi’s under-screen camera tech makes use of double the amount of horizontal and vertical pixels. This helps Xiaomi achieve an equivalent pixel density above the camera because of the rest of the display. Therefore, the world of the display above the embedded camera has equivalent brightness levels, color gamut, and color accuracy because of the remainder of the display.
