Fully 3D-Printed OLED Display - Timelapse

In a groundbreaking new study, researchers at the University of Minnesota Twin Cities used a customized printer to fully 3D print a flexible organic light-emitting diode (OLED) display. They combined two different modes of printing to print the six device layers that resulted in fully 3D-printed, flexible organic light-emitting diode displays. The electrodes, interconnects, insulation, and encapsulation were all extrusion printed, while the active layers were spray printed using the same 3D printer at room temperature. The display prototype was about 1.5 inches on each side and had 64 pixels. Every pixel worked and displayed light. Read more:
