The Holst Centre has fabricated two flexible OLED lighting panels and gave them to the Queen of the Netherlands (one will be given to the Slovakian president). The OLED panels are placed inside 3D-printed curved frames:
The OLED panels are lighting photos of the Queen's grandchildren and a couple of photos from her visit to Slovakia. The photos are black/white masks with resolution 20 micron which are placed on the top of the OLED panels. The Holst centre can actually create these images directly in the OLED (i.e. a structured OLED), but this time they just placed the mask in front of the OLED because of a tight schedule. I'm not sure if that's the most impressive flexible OLED demonstration I've seen, but it sure is a nice gift for the queen.
