Presentation Summary

Using simple equipment, like air brushes, all the layers in an LECs can be manufactured entirely in ambient conditions. This has been proven both on 50x50 mm2 glass substrates as well as on 50x50mm2 flexible substrates and lays the foundation for transfer into printing processes.

Company Profile (LunaLEC)

LunaLEC logo
LunaLEC AB is a spin-off from Umeå University in Northern Sweden, developing light-emitting patches based on the light-emitting electrochemical cell (LEC). The LEC is very similar to a large OLED pixel, or an OLED panel for lighting. A sandwich construction with an active layer in between two electrodes. However, it consists of no more than three layers, all printable from solutions in ambient condition. LunaLEC developed a spraying technology which enables the deposition of electrodes and active layer on flexible barrier substrates in ambient conditions. LunaLEC was named one of Sweden's hottest start-ups in 2017 by the tech magazine NyTeknik.
