Development of active matrix LCD for use in high‐resolution adaptive headlights

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. By integrating an active‐matrix liquid‐crystal display module, it is possible to realize fully adaptive high‐resolution headlamps without mechanical elements and a finite number of LED with 30 k switchable pixels. The realized monochrome display is able to withstand high illuminance (≥20 Mlx) and high temperature (80°C) at the same time while providing reliably a contrast ratio up to 490:1.
