Abstract

Meanwhile ADB Headlamps are stateof the art and available in huge variability of technical solutions in most of thecar segments. The latest improvement is the HD84 Matrix module which realizeslow beam, ADB and additional functionalities by using 84 switchable LEDs. Thistechnology is already available in two serial cars.

Now the discussion is going onintensively to increase the number of switchable pixels. In the VISION 2014article we presented the different technological solutions to extend the numberof switchable pixels to several thousand without having the correspondingnumber of LEDs and without usage of movable elements.

The solution of a LCD Displaypowered headlamps is under development and evaluation in the BMBF foundedproject VoLiFa, which was presented on 2015’s ISAL.

About one year later the first testcar equipped with a full headlamp integrated LCD is realized by the consortium.We will show the headlamp and present results out of the first test drives onperformance and system behavior. Furthermore we discuss the main elements ofthe LCD module related to the project partner’s achievements during run-time ofthe VoLiFa project.
