Bioinspired reflective display based on photonic crystals
INTERDISCIPLINARY MATERIALS(2024)
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. Reflective displays have the advantages of energy efficiency, high brightness, eye protection, and good readability. Photonic crystal (PhC) structural color is highly regarded as an ideal choice for reflective displays for its ecofriendliness, colorfastness, and adjustability. This review outlines the mechanism, types, design and preparation process of PhC-based reflective displays, focusing on the work principles, promising applications, and challenges of PhC display.image
