Digital OLED taillights alter the rear light signature | Technology

In 2016, technology OLED on board the Audi TT RS marked the beginning of a new era of lighting technology in the automotive sector. This is the first time that organic LEDs (or OLEDs) have been used for taillights.

OLEDs are elements semiconductors that generate a homogeneous and high-contrast luminous surface.

Their degree of brightness can be adjusted.

The light source can be freely configured and divided into precisely activated segments.

Four years later, Audi developed the technology OLED with digitalization on the Audi Q5.

The digitalization of lighting makes it possible to change the rear light signature by turning certain rear lights on and off to customize the light design.

This function is due to the fundamental properties of OLED technology: high contrast, the possibility of segmentation, great light homogeneity and minimal gaps between segments.

How do the lights work?

The bus system allows individual control of each rear light panel and the OLED segment inside. In this way, the preferences of each driver can be implemented via the MMI system. The driver can choose between three rear light signatures from the MMI system on the Audi A8.
