Printed organic lighting and signage

Organic light-emitting diodes (OLEDs) are set to revolutionize lighting and signage. They could cut lighting-related energy use by 50-90% and can create effects that no other technology can, such as transparent windows that light up after dark. OLEDs have another big advantage: they can be printed. This reduces production costs and offers almost limitless design freedom.

This program aims to demonstrate that cost-effective, flexible OLEDs for lighting and signage can be made using roll-to-roll production processes. To do this, Holst Centre and its partners are investigating both device designs and manufacturing techniques including:

  • Processing robust, large area OLEDs on flexible metal and plastic foils
  • Innovative device designs to minimize the number of process steps for OLED foils 
  • Low-cost alternatives to indium-tin oxide for transparent electrodes 
  • Top and bottom emission configurations 
  • Optimized light outcoupling

The end goal is OLED applications with lower cost of ownership, greater versatility, more pleasant light, longer lifetimes and lower energy needs than traditional lighting sources like fluorescent tubes. To this end, the program brings together partners from throughout the value chain, from materials suppliers through production equipment manufacturers to lighting, consumer electronics and design companies.
