Obviously they won't have a screen anymore. They'll be pop-up displays. So if you're sitting on a train and your romantic partner sends you a steamy selfie...guess who has an audience?
Has this annoyed anyone else?
If they're tactical screens, that makes sense. But I still don't think transparent displays on personal devices will be a thing in the future.
It's like that trick where you take out the polarizing layer in a screen, then you can only see the screen if you have the polarizing layer in front of your eyes
