The patented Xiaomi smartphone uses a flat screen with a full-screen design and a very narrow screen border. At first glance, there are no cameras on the front and back of the phone, but the patent documents show that it integrates dual cameras on the top of the device and appears in a pop-up way.
A special function of the camera system is that two cameras are located on the front and back of the mobile phone, so it always includes four cameras, two of which are self-timer cameras and the other two are rear cameras.
On the back of the phone, the flash is at the top, and when the two cameras pop up, it is right between them. In addition to the flash, the whole back is also very fashionable and has a certain curvature, which is more conducive to the user's grip.
The physical buttons of this Xiaomi mobile phone are concentrated on the right side of the frame, which is likely to be the volume button and the power button. There is a USB-C interface at the bottom, which integrates dual speakers. The microphone is located on the right side of the pop-up camera system.
It is not known whether Xiaomi will mass-produce this device. The camera system also looks more fragile than many pop-up cameras, mainly because it is two narrow pop-up designs that pop up from the fuselage at a certain angle. In addition, each pop-up system must also integrate two cameras, which is technically very difficult.
It can also be seen from this design patent that in recent years, in order to present a complete screen to users, mobile phone manufacturers have made many attempts on the front camera. Pop-up camera is undoubtedly one of them, but this scheme is still not the optimal scheme, because it will increase the thickness and weight of the mobile phone. Xiaomi's patented gimmick of dual pop-up camera design is greater than practicality. At present, the off-screen camera technology is undoubtedly the best solution to realize the real full screen of mobile phones. However, although mass-produced mobile phones have appeared, there are still some display problems, and it will take some time to mature.
