Samsung's OLED Screens

[JohnnyYesterday]

So they made a real transparent screen. I've been seeing those things in SF movies since the late '90s, and I still don't understand the point. Why would you want to see what is on the other side of the screen?* Supposing that there is a reason to desire that, why not just put a little video camera on the other side and have the screen display the video?

Screen contrast > transparency gimmick

*Windows, windshields, and HUDs make sense, but that's it.
