Audi started using 'Digital OLED' technology in its lighting systems. Audi, a pioneer in this field by using organic light emitting diodes (OLED) in lighting systems in 2016, aims to digitalize this technology, contributing to road safety on the one hand, and allowing the rear lights to be personalized on the other hand.
Headlight systems, which are among the most important systems of a car when it comes to safe and comfortable travels, continue to use a new technology every day. Audi, which has shown a rapid development in headlight and lighting systems technologies with the studies it has carried out in recent years, now once again demonstrates its leadership in this field by digitizing the rear lights of its cars.
High efficiency with less energy
Unlike LEDs, where point light sources made of semiconductor crystals are used, OLED technology, which consists of panel radiators, produces a homogeneous, high-contrast light and allows unlimited dimming. In this way, this technology, which can create individually controllable light segments, opens many doors in terms of design with its efficient, light and flat shape, since it does not require any reflectors, optical fiber or similar optical material.
Also, an OLED lighting element is only one millimeter thick, while conventional LED solutions require much more depth of 20 to 30 millimeters. On the other hand, the energy requirement of an OLED is much less than the energy required by the LED optics to achieve similar uniformity.
Rear lights that turn into a screen
Starting to use OLED technology built into the rear lights of the Audi TT RS model, which was first produced in 2016, Audi is now switching to digital OLED technology. Thus, the rear light system, which almost turns into a screen, brings new opportunities for the future in terms of design, customization, communication and security.
Its contribution to security has also increased
A proximity detection feature is used in the digital OLED tail lights. If another vehicle comes closer than 2 meters from the rear, all OLED segments light up and return to their original form when the distance starts to increase.
Carrying out many studies for international decision-making authorities on the use of dynamic signals and playing a major role in bringing this technology to the automotive world, Audi has already started working on digital OLED technology to be seen as traffic warning symbols in the future. Pre-defined symbols that can give early warnings to other vehicle users in traffic on matters that may cause danger such as slippery roads or traffic jams, will be used in the future for safer driving ...
