Head-Up Display (HUD)

Abstract
It is known as Head up display because while using it the operator’s head position is UP means forward instead of looking down. A head-up Display, HUD, is a safety feature for automobile drivers.HUD can be fitted in place of windscreen which will give the view of road plus the required information. HUD is the outcome of GPS and compass based data about a vehicle position and the emergence of computer vision technology that can recognize objects on and around the road and the navigational information as transparent colored paths. Head up displays (HUDs) are available in aircraft industries from a long time and they are now finding way into automotive industry also. 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, rearprojection screen 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. The uniqueness of DLP Technology makes it possible to solve common design challenges of Head-Up Display systems including managing environmental extremes and thermal loading, delivering high brightness and high resolution, and implementing dynamic dimming capabilities. Additionally, DLP projection-based architecture provides flexibility in the optical design needed to create very large field of view virtual displays over the road that augment and assist the driver. This paper includes a brief overview of DLP solid state illumination operation and how the implementation of DLP technology can solve the common HUD design challenges listed above.
