Audi Light Technology Evolution (1903 to 2022) and Future of Audi Light / Audi Matrix and OLED

How Audi’s light digitization is pointing the way toward the future

Audi Speed of Light Reloaded
This film shows the use of a wide variety of head and rear light technologies over the years on Audi models from 1903 to the present.

Completely digitized light in the Audi A8
The forward-looking Digital Matrix LED headlights and digital OLED rear lights in the new Audi A8 raise the customer experience to a whole new level: for the first time in any Audi model, light is completely digitized.

Headlights
Digital Matrix LED headlights with DMD technology
The Digital Matrix LED headlight can deliver cornering, city, and highway lighting as versions of the low-beam light with exceptional precision. It supplements the high-beam light by masking out other road users with even greater accuracy. DMD stands for digital micromirror device, a chip with around 1.3 million micromirrors that makes projections from the headlights possible. It disperses the light into tiny pixels and makes innovative functions possible, like the lane light, orientation light, and advanced traffic information. These innovations support the driver and increase safety in traffic.

Rear lights
OLED rear lights
OLEDs are organic light-emitting diodes that are less than a millimeter thick. Their name is derived from the organic semiconductor material they are made of. A low electric charge of 3 to 4 volts is enough to make the thin layers glow. Unlike point-light sources like LEDs, OLEDs are panel radiators. That means the light is more homogeneous than ever before and can be divided into individually dimmable segments. Optics like reflectors or optical fibers are unnecessary, making OLED units efficient and lightweight. At their debut in 2016, the OLED rear lights in the Audi TT RS had a total of 12 segments per light. In 2017, there were already 16 segments in the Audi A8.

Digital OLED rear lights
Since 2020, Audi has offered digital OLED rear lights in the Q5, making a variety of distinct taillight designs possible with just one type of hardware for the first time. Unlike the OLED rear lights in the TT RS, where every light function has its own conduit, the digital OLED rear lights are linked to the electrical system control unit via a bus system. That makes a significant amount of more functions possible. The technology has a larger number of individually controllable segments than the OLED rear lights that premiered in 2016. Three panels are used in one Audi Q5 rear light and each of them integrates six OLED segments. These can now be randomly activated, with continuous variability of brightness. Digital OLED technology has also been built into the rear lights as standard equipment in the new Audi A8 since 2021 – eight panels are used, each of which integrates six OLED segments.

Future technology: flexible digital OLED rear lights
While it has only been possible to integrate two-dimensional OLED panels into digital OLED rear lights as light sources up to this point, new bendable substrates in flexible digital OLED rear lights are now making curved OLED panels possible for the first time. This new leeway in design creates the possibility for a three-dimensional light design that fits into the body design even better. That means that the usable area for configuration, light design personalization, and communication with the immediate environment will once again be significantly expanded in the future. The core qualities of the technology, perfect homogeneity and high contrast, will remain – even from different perspectives.
