Hardly a new idea
Sony is already selling TVs that use the screen as a speaker.
The problem with going "notchless" (i.e. 100% of the front surface is screen) is that you have other bits like cameras that can't have pixels over the top of them.
Unless you go to that goofy pop up front camera (something that's just waiting to break off or become permanently popped in or popped out (remember the pop up headlights that used to be a fad, and how you'd see cars driving around with one popped up?) and are able to make the screen work as a microphone also, it seems there will at least have to be a hole or two in the screen. Maybe the notch haters would object less to a small hole in the display, or maybe they'd hate it even more because they'd feel they are SO CLOSE to being all screen, but not quite...
