Project description
Head-up display (HUD) systems have been used in recent car models to provide the necessary information to the driver while keeping the eyes on the road. Virtual image HUD systems have been the preferred method but they are not ideal for a car because of the large size of the relay optics. Direct projection HUD systems have been developed with a separate stand-alone screen on the dashboard, offering a compact but not elegant solution. In this paper we propose a direct projection HUD system based on a unique, windshield embedded transparent screen, which uses minimal space under the dashboard; offering an elegant and compact solution to the HUD problem.
