With the launch of the 2018 iPhones getting closer and closer, we're learning more about what's in store – or at least what insider sources say is in store. The latest report concerns the screen on the 6.1-inch iPhone, one of three expected to arrive in September.

As per Macotakara, the handset is going to use a "Full Active LCD", which means Apple will be able to shrink the bezels right down, although there's no indication in the report just how narrow the bezels might go. That matches up with what we've heard previously about every 2018 iPhone following the iPhone X design template.
