Abstract
We propose a novel flat panel-based head-up display (HUD) to realize a large viewing angle automotive display. The proposed flat-panel geometry is straightforward to integrate into the dashboard. We also provide a flat-panel compatible solution to eliminate the ghost image and stray-light in large field of view using space-variant polarization sheets and optimized directional filtering, respectively. The proposed system provides an image area that is about 14 times larger compared to commercial HUD, and the P-polarized virtual image is also viewable with polarized sunglasses. The virtual image distance in our experimental system is closer than in commercial HUD.
