Designed and prototyped an embedded smart display system utilizing a dielectric-coated reflective interface for optimized light transmission and reflectivity. Engineered the optical stack (dielectric mirror + LCD + SBC) to balance display luminance with ambient reflectivity, enabling high-contrast information visibility while preserving mirror functionality. Integrated real-time API-driven data modules (weather, calendar, IoT sensors) within a modular software architecture. Implemented motion-triggered activation and power management to enhance energy efficiency and user experience.
