The Notch, which Apple famously introduced in 2017 with its iPhone X as part of the almost bezel-less display, was at its introduction already more of a temporary solution than a real design feature. So far one of the main reasons why no manufacturer has built a truly bezel-less display is the fact that the camera for selfies and face recognition and various other sensors have to placed somewhere.
But now things are slowly changing. After in recent months a few devices were publisht, where the fingerprint scanner was installed under the display, AMS has now introduced an RGB light and IR sensor, which can also be installed beneath an OLED display. These kind of sensors so far have always been placed in the notch. Now however Apple might significantly reduce the size of the notch of its iPhone models, as these sensors can now also be installed beneath the display and AMS is one of the main suppliers of sensors to Apple anyway. Of course, other smartphone manufacturers could also benefit from this technology and reduce their notches in the future as well.
All that remains is the camera, which somehow has to be hidden. Samsung has recently presented a small solution for this problem with its Galaxy A8s: Here the camera is housed in a small hole in the display so that at least the edges of the display are even. However, this isn't really a final solution yet. In any case, it remains exciting to see where this trend will lead us and which technologies will emerge.
