OLEDs – or organic light-emitting diodes – offer quite a few benefits including lack of glare and excellent energy efficiency.
They sound amazing, but their uptake for commercial lighting applications has been slow.
Currently, the best-known uses for OLEDs are in televisions, mobile phones and handheld gaming devices. They provide good picture quality and a wider viewing angle while responding much faster than LCDs.
They are lightweight, cool and can be used for applications ranging from illuminated panels to textiles. They can even be used in 3D printing.
OLEDs are made using organic compounds that emit a soft light when electricity is applied. They produce illumination that is very similar to daylight. Because they don’t have a backlight, OLEDs also have a very slim profile, being only about one tenth of the depth of regular LEDs.
We know that daylight improves health, concentration and productivity, so OLEDs could be an excellent choice for healthcare centres and hospitals, offices or schools.
They could help to create the perfect background lighting for hotels and restaurants. They could also prove to be a ideal for museums, lighting delicate exhibits without heat and reducing the risk of damage. There are plenty of decorative possibilities too.
So, what are we waiting for?
First of all, OLEDs are still expensive compared to standard LEDs. To date, supply is also quite limited as the big manufacturers have not yet moved into high volume production. Predictions for cost-effective availability to the wider market range from four to seven years, but this new technology is expected to grow rapidly.
