Xiaomi’s patent for making a smartphone with a rotating camera inside the display

News unit EMGblog.com : Company Xiaomi is still progressing. This Chinese company knows very well how to offer its cheap and flagship phones. For example, the flagship Mi 11 Ultra or folding smartphone Mi Mix Fold clearly prove the high ability of Xiaomi. It was early 2021 that Xiaomi introduced a concept smartphone with 4 curved waterfall edges unveiled in which the front camera was placed inside the display. With this account, Xiaomi is one of the brands that is working on the in-display camera, and according to a patent recently published on the website of the World Intellectual Property Organization (WIPO), Xiaomi is looking to embed a dual-purpose camera in the display.

The application for this patent was submitted to WIPO in February 2020, and finally this 32-page patent was issued on April 29, 2021 (May 9, 1400) under the name Xiaomi was registered. Placing a selfie camera inside the display is not a new concept and even by ZTE – with the release of the phone ZTE Axon 20 – has also reached the commercialization stage. But what distinguishes Xiaomi’s design from other similar cases is that the camera inside the display is not only for taking selfies, but will also play a role as one of the rear cameras.

The smartphone depicted in this patent has 3 cameras on the back (something similar to the design of iPhone 12 Pro). The interesting thing is that one of these cameras, thanks to the presence of a motor or a magnet, can rotate 180 degrees towards the screen. In this way, the camera that was previously one of the members of the rear camera set, now plays the role of the in-display selfie camera. Apparently, a magnet mechanism is more likely to be used to rotate the camera, as it would be less expensive to implement and more durable (the motor may break, but the magnet will always work). The patent does not mention whether this rotating camera – which Xiaomi calls a flip camera – is supposed to be the main camera or the ultrawide camera, but either way, it seems like a practical idea.

According to what is mentioned in the text of this patent, a part of the screen is made in such a way that the light passes through it and reaches the camera lens. It’s not clear how big this transparent part is, but ZTE showed in the Axon 20 build that if done right, the transparent area of ​​the display is not very visible and can hardly be distinguished from other parts. Regardless of the size of the transparent area, this type of design allows Xiaomi to produce a smartphone with an all-over display without the need for a dedicated in-display camera. Another positive point is that in this type of design, Xiaomi can use a more powerful camera.

Finally, this patent mentions the laser auto focus system, which Xiaomi claims can focus with high precision and speed even in low light conditions. Of course, Xiaomi has implemented such an autofocus system in its devices in the past (like what we saw in the Mi 9). According to Xiaomi, there is no limit to the display in this design and any type of display – including OLED, LCD and even CRT – can be used.

Now, the question is, what are the advantages of using a rotating camera inside the display? First of all, it should be said that this camera has no contact with dust, and this can be a big advantage over pop-up cameras. Another benefit is that by using this rotating camera, you can save on the number of cameras used. And finally – what is most certain – with this rotating camera, there will be no need to install a separate selfie camera.

It is true that this patent was just an idea and may never be implemented, but this is the only attempt Xiaomi is not in the field of in-display camera. Also last year, a patent was registered in the field of smartphone design with an in-display selfie camera called Xiaomi, and this Chinese company confirmed that it will launch its first phones with this technology in 2021. According to some experts, Mi Mix 4 may be the first smartphone that Xiaomi uses an in-display selfie camera. Some rumors also indicate that the next generation of Xiaomi folding smartphones will be equipped with this technology.

Of course, in this field, Xiaomi is not alone. Reports suggest that Samsung’s Galaxy Z Fold 3 – which is expected to launch this summer – will feature an in-display selfie camera. In addition, other top brands are expected – including Oppo , Vivo and Huawei – will also launch their first phones with this technology this year. ZTE – which produces and sells Axon 20 in It’s a pioneer in this field – and plans to release another new model this year with an in-display selfie camera. Of course, it goes without saying that if Xiaomi can implement the idea presented in the recent patent and produce a smartphone with a flip camera, that smartphone will be a head above all the mentioned devices.
