Audi has always worked hard to improve the effectiveness of optical groups of its cars for safety at night or in the presence of low visibility. Now, the house of the 4 rings wanted to tell something more; on the maximum evolution of its lighting systems called Digital Matrix LED .
The digitization of optical groups and the introduction of avant-garde technologies such as Matrix adaptive high beam management, Digital Matrix LEDs and OLEDs allow you to explore new horizons for the benefit of safety, design, communication and connectivity; Car-to-X. LEDs and OLEDs no longer function from simple sources of lighting, bens & igrave; open up possibilities; of customization hitherto unknown, guaranteeing a new driving experience and relationship with the outside in support of individual and collective well-being.
SMART FUNCTIONS 
The digitization of optical groups therefore opens up new horizons on the fronts of safety, design and interaction with vehicles, cyclists and pedestrians. On the motorway, for example, the functions & ldquo; lane light & rdquo; and & ldquo; orientation light & rdquo;, features of Audi Digital Matrix LED headlamps, allow you to focus the attention of the driver and increase road safety .
Lane light generates a & quot; bright road & quot; which brightens the lane by adapting to changes in the car's trajectory. The orientation light, through the projection of the shadow areas, predictively shows the position of the vehicle inside the lane, favoring the maintenance of the center of the road. Now, the orientation light function is also available on country roads.
Still on the motorway, when you make a change of trajectory, the lane light illuminates both lanes involved in the maneuver, while the orientation light shows the position of the car. At this juncture comes a new function called direction indication. By activating the side indicators, the Digital Matrix LED headlights generate a section of flashing light that flanks the corresponding lane light, highlighting the change in trajectory in the stretch of road in front of the car. In this way, Audi goes to improve driving safety.
To all this is also added a function resulting from the interaction between lighting technology and Car-to-X communication .
If, thanks to the data shared through the HERE navigation and cartographic service provider, the Digital Matrix LED headlamps project a three-second warning on the road in front of the car via the MMI.
The new Audi Matrix LED headlights on the Audi e-tron Sportback and Audi A8 are characterized by having DMD (Digital Micromirror Device) technology, also used for professional video projectors.
The main component is a chip equipped with about 1.3 million micro-mirrors, the sides of which measure a few thousandths of a millimeter. Thanks to the generation of an electrostatic field, every micro mirror can change orientation up to 5,000 times per second. Depending on the position, the LED light is projected along the road or captured by such an absorber; to generate shaded areas.
In combination with the Night Vision system & egrave; also available the & ldquo; signal light & rdquo;. If the system detects the presence of a pedestrian, the light beam highlights it, reducing the risk of people on the side of the road not being seen. Thanks to DMD technology & egrave; It is possible to illuminate with greater depth; the inside curve is, once the car has stopped on the roadside, project a representation of the maneuver just performed in front of the car.
DIGITAL OLED 
Audi introduced digital OLEDs on the Audi TT RS in 2016 . In 2020, Audi & egrave; was the first manufacturer to integrate this technology into a mass production model such as the Audi Q5. Now, on the Audi A8 model year 2023, the house with the 4 rings goes further.
Equipped as standard with rear lights with OLED technology, the flagship of the four rings is; the first car in the Audi range to allow the rear light signature to be switched on board, using the MMI system. Thanks to the evolution of OLED technology, the customer can & ograve; opt for three (four for the Audi S8) different lighting configurations for the rear lights.
In addition to personalization, the OLED rear lights offer proximity signaling: when the car is stationary , if a pedestrian approaches less than two meters, the parking sensors register the movement and turn on all segments of the headlights, for the benefit of superior visibility.
On the Audi A6 e-tron concept, the house of 4 aneli is experimenting with the possibility; to generate quality animations cinematic. If, for example, these electric concept cars are parked in front of a wall while charging, the driver and passengers can spend time projecting a specially designed and developed video game onto it or onto the ground, using their smartphones as joysticks./p>

And for the future, Audi is also developing the second generation of organic diodes : the & ldquo; flexible & rdquo; OLEDs, characterized by thin plastic or metal supports that can be bent according to different orientations. The constructor will also introduce & agrave; additional lighting functions aimed at strengthening individual and collective safety such as the projection of the direction indicators on the ground.
Three symbols projected on the asphalt, both in the front and in the rear area of the & rsquo; cars, they will warn other road users, for example cyclists, of an impending lane change, or they will signal to pedestrians that the car is about to turn. This type of communication will open up; the road to more employment extended projections in the area surrounding the car.
