Smart Illuminator For Retroreflective Display Device

摘要

Method and apparatus features are implemented in a visual display system to provide coordinated interaction between an independent light source and a proximate retroreflective display. The light rays output characteristics of the independent light source are adjusted (e.g., by a controller) based on predetermined and/or detected viewing parameters of the retroreflective display. The retroreflected rays are targeted back toward an eye of a user associated with the independent light source to provide improved brightness and contrast for screen viewing by the user. Some retroreflective display screen embodiments may also include a self-illuminating mode as well as other non-retroreflective illumination modes of operation.
