Our partners in the Giebink Lab at University of Michigan, along with collaborators, have created a novel, high aspect-ratio OLED device architecture that uses “microscale ridges to pack more OLED into a given lighting panel area and lasts 2.7 times as long, with 40% higher efficiency, compared to conventional devices.”
Instead of the flat design that most displays employ, this method changes the form factor such that the devices can perform at higher outputs for longer periods of time, opening the door for uses beyond display, like room lighting.
“Normally when people build OLEDs, they go through a lot of trouble to make sure they have a pristine, flat surface. Our corrugated OLEDs exploit the third dimension and work surprisingly well even with tiny microstructural imperfections,” said Chris Giebink, U-M professor of electrical and computer engineering and physics and co-corresponding author of the study.
