And what does Xiaomi look like in all this? Well, as soon as the Oppo video   began to garner attention, Xiaomi decided to fight back on their Weibo and Twitter social networks, implying that they have also found the holy grail of full-screen phones.

Oppo  has been one of the most important manufacturers when it comes to looking for alternatives to the  notch on the screen, and Xiaomi for its part, as it was the one who started the trend for full-screen terminals in 2016 with the Mi MIX series . Now the companies reveal to us what could be the final piece of the puzzle. 

For his part, Wang Xiang, the vice president of Xiaomi, has given a more elaborate explanation of how this technology works, which was exhibited in a Xiaomi Mi 9 prototype .

According to the infographic shared by Xiaomi executives, the screen area above the front camera becomes transparent when taking a picture , thus allowing light to enter the sensor. The screen area has low-reflection, high-transmittance glass  to ensure that bright light that is naturally refracted on the screen does not impair image formation. 

In addition to acting as part of the AMOLED screen, this part of the panel also acts as a lens . The infographic also confirms that the process of interleaving between screen and camera makes no sound and is almost instantaneous. However, it is worth noting that  Oppo  has not yet explained how its technology works, and that it could be different from Xiaomi’s, but in the end the goal is the same.

It is also important to note that Oppo Vice President  Brian Shen explained that it is quite difficult to get the quality of an on-screen camera to be identical to that of an external camera, which implies that there will be a compromise between quality and convenience that offers this solution . 

Finally, neither  Oppo  nor Xiaomi gave information on when we could see this solution on the market, so we have to wait patiently, but if we can agree on something, it is that placing the camera under the screen looks like a promising solution to the dilemma. full screen and selfie camera  .
