Bioinspired reflective display based on photonic crystals

Abstract

Reflective displays have the advantages of energy efficiency, high brightness, eye protection, and good readability, making them an attractive display technology. Photonic crystal (PhC) structural color is highly regarded as an ideal choice for reflective displays for its ecofriendliness, colorfastness, and adjustability. In this review, we introduce the fundamental classification and manufacturing methods of PhC reflective displays. We systematically summarize the display principles of PhC-based displays driven by various stimuli. Furthermore, we present the latest research advancements in PhC displays based on smart actuators. Additionally, we offer a detailed overview of the current research status and application prospects of liquid crystal structural color displays and three-dimensional PhC displays. Finally, we discuss the challenges faced by PhC displays and provide insights into their prospects.
