レーザーヘッドアツプデイスプレイ

摘要

Head-up displays (HUDs) mounted on vehicles have been expected to significantly improve driving safety, since eye movements and accommodation during driving can be reduced with them. In this paper, laser projector, a micro-lens array used as a transparent screen, and a concave combiner, which consist of a brand-n (a) ew laser HUD, are reviewed respectively. A method for image distortion correction is also presented. A wide field of view (17.1 by 5.7 degrees), high brightness (12,000 cd/m2), and compact size (W260 × H123 × D257 mm) have been achieved with this HUD system.
