Conventional adaptive driving beam headlamps are limited in achieving still higher quantities of switchable pixels by the number of LEDs and movable elements needed. In this paper, it is shown that by integrating an active matrix liquid crystal display module, it is possible to realize fully adaptive high‐resolution headlights without mechanical elements and a finite number of LED with 30 k switchable pixels.

Conventional adaptive driving beam headlamps are limited in achieving still higher quantities of switchable pixels by the number of LEDs and movable elements needed. In this paper it is shown that by integrating an active matrix liquid crystal display module it is possible to realize fully adaptive high resolution headlights without mechanical elements and a finite number of light emitting diodes with 30k switchable pixels.

Vehicle headlamps that adapt to external conditions are established and available in mass‐production vehicles; now the market is requesting headlamp systems with increasing resolution. Active‐matrix LCD (AMLCD) with amorphous silicon thin‐film transistors (a‐Si TFTs) is a mature and cost‐efficient technology that is known for its reproducible and homogeneous performance. Integrating an AMLCD with a‐Si TFTs into an LED‐based headlamp can fulfill all specifications for realizing a fully adaptive headlamp setup with high resolution.
