The smartphone industry continues to evolve and the race for true frameless devices is becoming increasingly apparent. It looks like we've already seen all the design options designed to fill the device's maximum area with a screen. It started with a broad section, then a drop-down display and then a holey, a pop-up camera, two-screen options, a sliding design, etc.
Xiaomi showed her invisible self-portraits hidden behind the screen surface. Now Xiaomi's new patent points to a device with such a dual camera – perhaps the engineers of Chinese manufacturers are working in this direction. a smartphone with two self-portrait cameras hidden under the screen. This allows you to create a full-screen design without cropping.
For example, two cameras allow better facial recognition by analyzing the depth of the scene and the best process frames using neural networks. The latter is particularly important because the sensors hidden behind the screen currently do not differ in terms of photosensitivity and quality, and thus in particular require the use of machine learning algorithms.
