Xiaomi explains the operation of the invisible front camera

The thing, says Xiaomi, lies in the area of ​​the screen above the front camera. As soon as the front camera is activated, the surface becomes transparent and allows the incidence of light rays necessary for the front camera to take a selfie. For this reason, Xiaomi uses according to its own affirmations a special glbad, which reflects less and has a greater permeability to light rays.

Oppo and Samsung are also working on an invisible front camera

Xiaomi is not the only manufacturer to work on an invisible front camera. At the same time as the video of yesterday, Oppo also showed a built-in camera on the screen. In both cases, an OLED panel is used. As for Xiaomi, Oppo is an early prototype. Samsung is also working on a similar technique. For its Galaxy S10 smartphones, the industry leader has installed a camera hole, called "Infinity-O-Display". But this is only an intermediate step to a completely uninterrupted screen, without Notch or camera.
