Technology - Organic Light Emitting Devices

PolyPhotonix develops light treatment for retinal diseases. Using state of the art in-house facilities in partnership with the Centre for Process Innovation, we research the application of light-based therapies.


How do Organic Light Emitting Devices work?

Organic Light Emitting Devices (OLEDs) are based on electroluminescence in certain organic molecules and polymers. Passing an electric current through these materials creates an excited states which in turn emits light. Organic materials can be coated as ultra thin layers (less than 1/100th of the thickness of the human hair) using printing and vacuum processes.

Why are they so attractive?

The processability of electroluminescent organic materials and the ability to coat thin emissive films make OLEDs a very promising technology. OLEDs can cover a very large area - the size is only limited by the coating process. Thin films or panels can cover a ceiling or an entire wall. Once process technologies are established, OLEDs will be manufactured in large volumes, eventually reducing costs.

Highly Tunable

The materials and layer structures in OLEDs can be tuned selectively to adjust the color and brightness of the light generated. OLEDs can be of different shapes, sizes, it can be flexible, even transparent.


What are the creative opportunities?

OLEDs are excellent as a large area, diffuse light source for architectural surfaces, designer lamps, signs, and general illumination – even windows and window shades. One unique aspect of OLEDs is that they eliminate shadows.

Those thin and flexible surfaces can be integrated into products in our environment, in ways that are not possible with traditional lighting or light emitting diodes (LED). OLEDs open up unlimited opportunities to designers, from the fashion world, to product designers, artists and architects.
