With the rapid development of optoelectronic fields, electrochromic (EC) materials and devices have received remarkable attention and have shown attractive potential for use in emerging wearable and portable electronics, electronic papers/billboards, see-through displays, and other new-generation displays, due to the advantages of low power consumption, easy viewing, flexibility, stretchability, etc. Despite continuous progress in related fields, determining how to make electrochromics truly meet the requirements of mature displays (e.g., ideal overall performance) has been a long-term problem. Therefore, the commercialization of relevant high-quality products is still in its infancy. In this review, we will focus on the progress in emerging EC materials and devices for potential displays, including two mainstream EC display prototypes (segmented displays and pixel displays) and their commercial applications. Among these topics, the related materials/devices, EC performance, construction approaches, and processing techniques are comprehensively disscussed and reviewed. We also outline the current barriers with possible solutions and discuss the future of this field.
随着光电领域的快速发展，电致变色（EC）材料和器件受到了广泛关注，由于其功耗低、观看方便、灵活性好、可拉伸等优点，在新兴的可穿戴和便携式电子设备、电子纸/广告牌、透明显示器和其他新一代显示器方面显示出了诱人的应用潜力。尽管相关领域不断取得进展，但如何使电致变色真正满足成熟显示器的要求（例如，理想的整体性能）一直是一个长期存在的问题。因此，相关高质量产品的商业化仍处于起步阶段。在这篇综述中，我们将重点介绍潜在显示用新兴 EC 材料和器件的进展，包括两种主流 EC 显示原型（分段显示和像素显示）及其商业应用。在这些主题中，我们全面讨论和回顾了相关材料/器件、EC 性能、构建方法和加工技术。我们还概述了当前的障碍和可能的解决方案，并讨论了该领域的未来。
