Samsung shows an OLED "window" (30% transparent panels)

Samsung is showing a window made from OLED Panels (12.1", 840x504 with 200cd/m2 luminance). The panels are 30% transmittive - which means they are transparent. You can see in the image to the right how it looks. From the back the window is almost (70%) transparent.

Samsung declined to comment on the details of the technology that realized the high transmittance.
