Lighting OLED, the key of the riders in the rear of the BMW M4 GTS


The BMW M4 GTS is a special car and very important for the bavarian manufacturer. And it is not only by a demonstration of benefits that are difficult to match, with its 500 HP and a performance in a circuit outside of all doubt, as shown by their time at the Nürburgring of 7 minutes and 28 seconds: it is also a demonstration of the technology ahead of its time.

in Addition to an innovative water injection on your engine TwinPower Turbo of 3.0 litres, the BMW M4 GTS is the first production car to adopt optical technology OLED. If the BMW i8 opted to be a forerunner with its headlights laser, in the case of the M4 GTS stand out drivers rear BMW Organic Light, the first OLED in a car.


¿How works the OLED technology? Surely by now you have heard of those OLED displays that are beginning to be used in tvs or mobile phones. In the case of these optical rear, are composed of layers of semiconducting organic thin, usually polymers. Here we find the main difference with LED technology, composed of semiconductor crystals.

These polymers and the layered semiconductor are encapsulated hermetically between two layers of glass: the substructure in charge of light emission is about 150 times thinner than a human hair. The total height of an element OLED is measured between 0.8 and 1.5 millimeters, still really thin. In addition, its manufacturing and subsequent recycling generates less waste with the use of very little material, promoting the sustainability.


¿Light better headlights OLED LED traditional? The answer has to be “it depends”. At the moment it is not possible to use in headlights, for dipped headlights or road, hence to limit its use to the pilots in the rear or in the interior of the vehicle. However, future technological developments will facilitate greater outreach and versatility.

Among other advantages of this lighting OLED is a light more uniform across its surface and less focused, as well as a higher accuracy-can be activated individually selected modules, separately – and a lower generation of heat, being more thermally efficient. So, the headlights OLED consume less power, and in addition they maintain a high shelf life without minimal maintenance: in the future will be very popular as a complement to the technologies of LED and laser.
