Abstract

Photonic crystal (PhC) displays have garnered significant attention owing to their high color saturation, brightness, wide color gamut, and low energy consumption. However, existing PhC color modulation techniques still suffer from drawbacks such as slow response speed, short cycle life, poor control accuracy, and challenging pixel integration, which severely restrict their application in dynamic displays. Herein, we integrate a two-dimensional PhC film with an electroactive ionic polymer-metal composite (IPMC) actuator featuring titanium carbide/carbon nanotubes (MXene/CNTs) composite electrodes and achieve a dynamic PhC display with full-color-gamut switching. Color change of the prepared PhC display is electrically controlled, localized, and active, enabling precise pixel control. MXene/CNT-IPMC offers electrically addressable, high-speed pixelation which enables rapid color switching for dynamic displays. This synergistic integration of PhC films with actuation devices not only demonstrates their potential for display applications but also lays the foundation for dynamic reflective displays with low energy consumption, high brightness, and wide color gamut.

低能耗电寻址高速全色域动态光子晶体显示

光子晶体（PhC）显示器因其高色彩饱和度、高亮度、宽色域和低能耗而受到广泛关注。然而，现有的PhC颜色调制技术仍然存在响应速度慢、循环寿命短、控制精度差、像素集成困难等缺点，严重制约了其在动态显示中的应用。在此，我们将二维PhC薄膜与具有碳化钛/碳纳米管（MXene/CNTs）复合电极的电活性离子聚合物-金属复合材料（IPMC）致动器集成在一起，实现了具有全色域切换的动态PhC显示。所制备的PhC显示器的颜色变化是电气控制的、局部的和主动的，可以实现精确的像素控制。MXene/CNT-IPMC提供电可寻址的高速像素化，使动态显示的快速颜色切换成为可能。PhC薄膜与驱动装置的协同集成不仅展示了它们在显示应用中的潜力，而且为低能耗、高亮度、宽色域的动态反射显示奠定了基础。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
