A head-up Display, HUD, is a safety feature for automobile drivers. Although there have been some HUD systems in
commercial already, their images are too small to show assistance information. We demonstrated a HUD including
micro-projectors, rear-projection screen and a Fresnel lens and realized a 14 inches image on the windshield. It is able to
show speed, map-navigation and night vision information. We adopted digital light processing, DLP, as our image
source because of its brighter image output required. To minimize the model volume, we applied a Fresnel lens to
magnify the images from DLP projector. The size of the HUD model is 390 mm × 274 mm × 117 mm. It shows a virtual
image 1.5 meters from windshields and the brightness is 378 nits which is clear enough to be seen by drivers even during
daytime. Besides, it can also display information on a 7 inches instrument panel simultaneously.
