Comparable to the methods used in video projectors, the digital matrix system Digital Matrix LED headlights new Audi A8 uses technology for computer-controlled micro-mirror devices DMD (Digital Micromirror Device).
Approximately 1.3 million micro-mirrors are built into each of the headlights, which distribute the light flux into small pixels and thus allow it to be controlled with maximum precision. Among the new features that became possible with the implementation of the system is that of lane lighting and orientation when driving on the highway.
In this case, the headlights emit a kind of “light path”, which illuminates its own lane particularly brightly and thus intuitively guides the driver when following it – something very useful in areas with road construction and unclear markings. The Matrix LED digital lights also have dynamic functions for meeting / sending from home when unlocking and leaving the car, which are projected as light pictures on the ground or on the wall.
In the standard equipment The advanced A8 also includes digitally controlled OLED taillights (OLED = “organic light-emitting diode”), offering a choice of two “stop” light graphics (three on the S8). When the “dynamic” mode of Audi drive select is selected, the light graphics change to a wider profile, which is used only in this mode.
In combination with the assistance systems, the digital OLED taillights offer a proximity notification function – if another vehicle approaches from behind within two meters of the stationary A8, all OLED segments are activated. Other additional features include dynamic turn signals as well as light profiles with a specific sequence when receiving / sending from home.
