I expect there to be phones released that have a see-through display, mostly gimmick early stuff that are basically nothing but an empty bezel ring.

Probably not anywhere in the near future, unless we’re talking a huuuuge bezel. You’re phone isn’t exactly empty space inside so you’d either need those to be transparent as well, or you’d need to fit them all one the bezel… so either you’ve got a big bezel or terrible battery life, probably :P. This is all speculation of course. Frankly, I could only really see a company doing it as a publicity stunt because I can’t imagine such a phone would be… good? Cool, yes… But having a transparent display sounds horrible!

Technically there are phones that utilize “transparent” screens right now, for things like under display cameras. So, there’s definitely use cases for the technology, and cool stuff you could do with it, but I’m not convinced you’d want a fully transparent display in a phone. Maybe headsets or glasses or something.
