Following the use of OLED technology in production vehicles (Audi TT RS) since 2016, the car manufacturer intends to present the next evolution stage - digital OLED technology - at ISAL (September 23, Darmstadt, Germany). While previous Audi models use up to four freely designed complex light segments to create a fixed design, the new digital OLED technology enables personalizable lighting design in rear lighting.
For this purpose, the OLED light source is divided into a significantly larger number of individually controllable segments. These more than 50 segments can be activated at will and their brightness can be infinitely adjusted. This enables designers to display a wide variety of lighting designs with a single hardware. The OLED advantages are very high contrast, high homogeneity and minimal segment spacing. The high system efficiency as area light in a one millimetre thin light element is retained.
The Audi engineers' ideas go beyond aesthetics and design: in addition to the versatile design of lighting, the digital OLED can also be used as a display element in rear lighting and thus as a car-to-X communication element. For example, predefined symbols can be displayed to alert other road users at an early stage to local hazards such as slippery roads or an imminent end to a traffic jam.
At ISAL, Audi will present its new OLED developments with a demonstrator.
