What do molecules have to do with your smartphone display? Quite a lot. Organic light-emitting diodes (OLEDs) enable the bright and vibrant images we see every day.
In the latest episode of our “Explain Like I’m Five” series, Lisa Janz, Cluster Doctoral Researcher at Karlsruhe Institute of Technology (KIT), explains how OLEDs work and why molecular design is key to their performance. She shows how organic molecules convert electrical energy into light and why blue emitters are particularly challenging. Their higher energy makes them more prone to degradation. In her research, Lisa develops new luminescent molecules for OLEDs, using computational methods and advanced 3D printing techniques to integrate promising materials into devices. Her goal is more energy-efficient, durable displays with brilliant colors.
