Abstract
Market penetration of automotive head-up displays (HUD) is increasing and extending from higher-end models to midrange and even compact cars. New HUD use cases will be motivated by autonomous driving as well as improved HUD abilities. Holographic 3D (H3D) HUD will contribute to further improve the usability and attractiveness, specifically by presenting images with a full consistency of all depth cues. Based on results from H3D-HUD implementations, it is explained how H3D images are created and how viewers benefit from the unique 3D solution that eliminates ambiguity of the presented information and improves safety by properly overlaying virtual 3D objects with the real world. The difference between possible SLM options is explained, including references to ongoing development of high-resolution phase-modulating micro-mirror-based SLM (micro mirror arrays, MMA). It is compared how use of MMA vs. LCoS can improve selected features and the user experience. Ongoing development of MMA in a consortium of expert companies and institutions and results of already manufactured MMA are presented.
