BMW is demonstrating a new concept car, the M4 Concept Iconic Lights with two new lighting technologies - the laserlight headlights and the OLED based tail lights and rear direction indicators. BMW is using many small thin OLEDs to create a 3D effect.
BMW says that they will launch a production model with OLEDs in the "near future". In April 2014 BMW said that the future lighting technology for their automobiles will be OLED, and that BMW expects to start selling cars with OLED lighting within 3 years.
For the first time, both the tail lights and rear direction indicators feature OLED technology, with the illuminated surfaces being positioned to produce a three-dimensional effect. Another advantage of using OLEDs is that they take up less room because of their thin size (1.4 mm).
In 2014, BMW demonstrated two different OLED concepts, one with OLEDs made by Astron Fiamm and another with OLEDs made by Philips. We also know that LG Chem is collaborating with BMW on OLED lighting. It'll be interesting to see which OLED maker will be chosen for BMW's first commercial car (but we'll have to wait at least 2 years for that).
