If 2018 was the year of notch then 2019 has already proven to be the death of notch on smartphones. Xiaomi, Samsung, Oppo, Vivo, Realme and Asus have all launched new smartphones that feature full-screen displays without a notch or cut-out of any form. The biggest challenge for smartphone makers to create a truly bezel-less fullscreen smartphone has been the front-facing camera, microphone, and other sensors. The above-mentioned smartphone makers have achieved achieving such a design and form factor by adopting a pop-up selfie camera mechanism. Asus, has in fact, gone a step further by including a flip camera mechanism that does the dual duty of front as well as the rear camera.
The holy grail in this quest to design a true all screen smartphone experience would be to embed the front camera under the display, just like the optical fingerprint sensors placed underneath the display. There are already reports of Huawei, Samsung and Oppo working to put a camera underneath the display and make it see through the display and now a patent application suggests Xiaomi could be the newest addition to this growing list of smartphone makers working on such a technology.
The patent filed by Xiaomi has surfaced on the internet which shows the Chinese smartphone maker’s ambition to introduce an in-display camera on its devices. The translated version of the patent application states that Xiaomi plans to include a secondary display under the main display which will be in front of the selfie camera and light sensor. It will reportedly work in such a way that the camera will become visible whenever required and invisible when not in use. How Xiaomi will make the camera visible or invisible depending on need remains unknown but the company seems to have at least devised a plan to make it possible.
