Audi has revealed that the next generation of its lighting technology programme will see the introduction of OLED (Organic Light Emitting Diode) Lights. The Ingolstadt based company will showcase a concept car featuring tail lamps that will sport its new Matrix OLED lights for the first time at the International Motor Show (IAA) in Frankfurt this September (Frankfurt Motor Show 2015).
The lightweight and energy efficient OLED lights have been developed over the years with the company calling it a perfect synthesis of cutting edge technology and design. Each OLED consists of two electrodes along with multiple thin layers of organic semiconductor material. The layers that are one thousandth of a millimetre thick turn on when a low DC voltage current of 3 to 4 volts is passed with one of the electrodes being transparent.
The light emitted from the OLED’s achieve a new level of homogeneity with dimming that can be continuously varied, compared to LED’s which are made of crystal semiconductors says the company. The light emitted from the flat light source does not cast any shadows and also negates the need for light guides, reflectors and cooling.
The organic sheets that are encased in thin sheets of glass currently is expected to be replaced by plastic materials as the technology evolves in the future, opening up new design possibilities like three dimensional forming for engineers. Audi is presently working to incorporate the new Matrix OLED technology into the rear lamps of the future production models.
