Researchers from Korea's Yonsei University has developed a 3D printing technique that can be used to deposit transparent OLED displays on any shape. The new technique 3D prints both the support structure and the 3D screen electronics.

The method is based in Digital Light Processing (DLP) system that prints the transparent plastic frames, and then uses an electrohydrodynamic jet (e-jet) printer to create the OLED layers as seen in the image above.

This is an interesting proposal - although it is not clear what is the big advantage over using flexible OLED displays which can be flexed to fit 3D frames.
