With transparency, a display could be illuminated from the back or front. That means the OLEDs could be embedded into laminated glass—that means a car windshield, or even the windows in an office building, could offer a clear view out but also be turned into display panels when needed. Fascinating stuff, no idea how long until we see these on the market. They are still perfecting the manufacturing process for larger surfaces, so expect to see it in handheld devices first.
This is very cool technology and would be great to see it in use in the future. Only downside right now though, is that OLED tech is still very expensive so it would be quite a while before it would be remotely affordable. Check out the full posting at Gizmodo.
