Dual-Functional Transparent Projection Film with Privacy Protection via Cholesteric Liquid Crystal Polymer Networks.

ABSTRACT: Transparent projection screens are widely used across various industries for applications that require overlaying digital content onto real-world environments while maintaining high transparency. However, existing technologies face challenges in balancing transparency, projection quality, and privacy protection. In this work, a novel transparent projection screen is  based on cholesteric liquid crystal (CLC) polymer networks is developed. The CLC networks are designed and fabricated to have a small birefringence to achieve a narrow bandwidth. This allows a selective reflection of designed colors for full-color projection, while allowing other light to transmit. The CLC films, designed with multi-layer CLC networks, selectively reflect red, green, and blue light to achieve high-quality full
