Here’s how Xiaomi’s in-display selfie camera tech will work

Xiaomi has come up with its own, proprietary solution to the all-screen smartphone display conundrum, by placing the front-facing camera underneath the display glass. The solution, which the company claims is an in-house engineering effort, installs the front-facing camera underneath the display panel, and instead of the usual display panel, uses a more advanced setup with charged electrodes on either side of the OLED display, which help turning it transparent. It then uses the screen’s glass as the optical lens for the front camera to create a front camera that always remains invisible to the human eye.

With smartphone display panels attempting to reach a point of no bezels, cut-outs, notches or pop-up mechanisms, the quest is on to find the ultimate solution for accommodating a front camera and an all-screen front, at the same time. The present mechanisms in place are functional — both notches and cut-outs make a smartphone look relatively advanced, while the pop-out formula makes devices look decidedly futuristic. But, notches and cut-outs still present an obstacle to letting a user utilise the full display, while pop-out mechanisms compromise the device’s longevity. An in-display camera, meanwhile, will allow users to make use of the entire display when viewing content or playing games. When the time comes, switching on the front camera would induce a specific charge to the transparent cathode and anode on either side of the display, which in turn render the OLED display crystals as transparent too…Read More>>>
