Comparable with video projectors, the Digital Matrix LED headlights use DMD (digital micromirror device) technology. Each headlight has approximately 1.3 million micromirrors that break down the light into tiny pixels. This allows it to be controlled with maximum precision.One new function that this makes possible is lane and orientation lights for highways. The enhanced A8 comes with digital OLED rear lights (OLED = organic light-emitting diode) as a standard feature. In conjunction with the assistance systems, the digital OLED rear lights have a proximity indication feature.
