This has a lower pixel density and Transparency Enough to take pictures. The result isn’t terrible, it has a cameo effect, but the principle is there. Today during Mobile World Congress From Shanghai, the brand has revealed an improvement in this process. This time, it’s a 3D face recognition system to unlock a mobile phone, like Face ID.

To compensate for screen opacity, pixel strength is in tourch That used in facial recognition has doubled by ten compared to what is done in other systems.

Get out of the cracks and punches in the screen

And that’s not all, due to giving a display more consistent with the rest of the screen, the pixel density of the tiny panel covering the sensor has been increased from 200 to 400 dpi.
