Bragg WOLED

Funded by Business Finland

The global general lighting market is 30 B$ (2020) and reaching 43B$ by 2027 with a Compound Annual Growth Rate (CAGR) of over 5%. However, current lighting solutions have negative environmental impacts because they contain rare earth and toxic heavy metal traces. Governments globally apply stricter regulation and pressure for reducing CO2 emission, resulting in a CAGR of 34% for lighting products that are ecological and have a smaller carbon footprint.

We have currently developed and already successfully patented in Finland a fully functional white organic light-emitting diode (WOLED) prototype in our laboratory using a single purely organic light-emitting material and a novel photonic design that we call “Bragg converter”. Our goal in the R2B is to introduce to the market our new white organic light-emitting diode (WOLED) device architecture. During the R2B project, we will focus on increasing the luminous efficacy (efficiency) and luminance (brightness) of our WOLEDs in order to reach the general illumination standards (lighting applications). We anticipate that further funding will come from future industrial partners.
