A research team within the Department of Materials Science and Engineering at the Nano Science Technology Institute at Yonsei University (Seoul, Korea) is developing a 3D printing technique that enables OLEDs to be printed onto transparent structures of any shape.
The result: “nearly anything can become a see-through color display.”
First, a few words of background information. Previous approaches to the production of freeform, transparent displays utilizing conventional technologies are reported as suffering from high fabrication cost and unnecessary waste of materials. In addition, since conventional approaches typically involve the use of photolithography, it is only possible to fabricate 2D structures on a flat surface. One alternative technology that can overcome the limitations of conventional approaches is based on direct 3D printing. However, up till now, such approaches have experienced problems of their own including limitations on the inks that can be printed and the resolution of the printing. […]
